Which best compares and contrasts how John Newlands and Dmitri Mendeleev organized elements?
Both Newlands and Mendeleev arranged elements according to their chemical properties, but only Newlands used a
mass as well.
O Both Newlands and Mendeleev arranged elements according to their atomic masses, but only Mendeleev used cherr
properties as well
Both Newlands and Mendeleev organized elements into groups, but only Newlands used a table with rows and column
Both Newlands and Mendeleev organized elements into a table with rows and columns, but only Mendeleev named
different groups of elements.

Answers

The correct answer is B. Both Newlands and Mendeleev arranged elements according to their atomic masses, but only Mendeleev used chemical properties as well.

Explanation:

Both John Newlands and Dmitri Mendeleev were relevant chemists, mainly known for designing the period table, which organized chemical elements. In the case of Newlands, he designed his period table around 1865 by organizing the known elements based on the atomic masses of elements (number of protons and neutrons); also, he divided elements into groups.

On the other hand, Mendeleev designed his periodic table around 1869; in this, elements were also arranged by their atomic masses, but Mendeleev considered the properties of each element such as electronegativity, which implied some minor changes in order, as well as leaving some spaces for elements that had not been discovered, but that Mendelev could predict. Thus, the option that compares the organization in both periodic tables is B.

Answer:

B. Both Newlands and Mendeleev arranged elements according to their atomic masses, but only Mendeleev used chemical properties as well.

Answers

Cobalt is an essential material that is mainly used in lithium ion batteries which are found in smartphones and some electric vehicles. Congo provide majority of the worlds supply of cobalt. Although having a surplus of valuable materials, Congo is one of the poorest nations. Because of the lack of money, those who mine cobalt in the Congo do not used power tools, gloves or mask, but instead they use their hands. With that, the miners would be exposed to high level of cobalt. Lung disease and heart failure have been linked to high levels of cobalt, and the mines that produces it are blamed for destroying landscapes, polluting water sources, contaminated crops and a loss of soil fertility.

Explain how scientific knowledge is developed when people make observations about the natural world.

Answers

Answer:

Scientific knowledge is developed only when you make an observation about the natural world because without an observation, you will not question anything which mean there will be no scientific knowledge about the world around us. Scientific knowledge is built as people come up with hypotheses and theories, repeatedly test them against observations of the natural world, and continue to refine those explanations based on new ideas and observations. Observation is essential to the process of science.

Which must be true for metamorphism to occur?
A. The parent rock must be in liquid form.
B. The parent rock must be igneous.
C. The process must take place underground.
D. The grain size must become smaller.

Answers

The parent rock must be in liquid form, must be true for metamorphism to occur. Hence, option A is correct.

What is  parent rock?

Parent rock is the fundamental rock that something else was produced from. It is mostly applied in the context of soil formation, where the parent rock typically has a significant impact on the final soil's composition.

Sandstone, shale, and limestone fall within this category. Metamorphic rock is the last type of parent rock. Extreme heat or pressure have resulted in the formation of metamorphic rocks. As a result, igneous or sedimentary rock changes in composition.

Thus, option A is correct.

Explain how scientific knowledge is developed when people make observations about the natural world.

Answers

We typically think of observations as having been seen "with our own eyes," but in science, observations can take many forms. Of course, we can make observations directly by seeing, feeling, hearing, and smelling, but we can also extend and refine our basic senses with tools: thermometers, microscopes, telescopes, radar, radiation sensors, X-ray crystallography, mass spectroscopy, etc. And these tools do a better job of observing than we can! Further, humans cannot directly sense many of the phenomena that science investigates (no amount of staring at this computer screen will ever let you see the atoms that make it up or the UV radiation that it emits), and in such cases, we must rely on indirect observations facilitated by tools. Through these tools, we can make many more observations much more precisely than those our basic senses are equipped to handle.

Tools like the Hubble Space Telescope, microscopes and submersibles help us to observe the natural world.

Observations yield what scientists call data. Whether the observation is an experimental result, radiation measurements taken from an orbiting satellite, an infrared recording of a volcanic eruption, or just noticing that a certain bird species always thumps the ground with its foot while foraging — they're all data. Scientists analyze and interpret data in order to figure out how those data inform their hypotheses and theories. Do they support one idea over others, help refute an idea, or suggest an entirely new explanation? Though data may seem complex and be represented by detailed graphs or complex statistical analyses, it's important to remember that, at the most basic level, they are simply observations.
Observations inspire, lend support to, and help refute scientific hypotheses and theories. However, theories and hypotheses (the fundamental structures of scientific knowledge) cannot be directly read off of nature. A falling ball (no matter how detailed our observations of it may be) does not directly tell us how gravity works, and collecting observations of all the different finch species of the Galapagos Islands does not directly tell us how their beaks evolved. Scientific knowledge is built as people come up with hypotheses and theories, repeatedly test them against observations of the natural world, and continue to refine those explanations based on new ideas and observations. Observation is essential to the process of science, but it is only half the picture.

Answer:

Scientific knowledge is developed when people make observations about the natural world. An observation may generate a scientific question, which may lead to a hypothesis. The hypothesis can be tested through experimentation. The results of the experimentation may lead to changes in scientific knowledge.

Scientists find trilobites during a routine dig. Trilobites were common in the Paleozoic Era (540 to 245 million years ago) and went extinct during the late Permian period (248 million years ago). On another site, the scientists find ammonites. Ammonites lived during the Mesozoic Era (245 to 65 million years ago) and are not found after that period. What can be concluded about the rock layers? Choose all that apply.


A The rock layers must have formed at the same time because they both contain biozones.


B The rock layer containing the trilobites must have formed before the one containing the ammonites.


C The rock layer containing the trilobites must have formed after the one containing the ammonites.


D The rock layers must have formed at different times because they contain two different biozones.

Answers

Answer:

A and C

Explanation:

The rock layers must have formed at different times because they contain two different biozones. The rock layer containing the trilobites must have formed before the one containing the ammonites. The key thing to note here is that the Trilobites only lived from 540 to 248 million years ago. And that the Ammonites were from 245 to 65 million years ago. So there's a 3 million year gap between these 2 different creatures where neither of them existed. So the dig where the trilobites were found has to be at least 3 million years older than the dig where the Ammonites were found. So with that in mind, let's look at the options and see what makes sense.

The rock layers must have formed at the same time because they both contain biozones. * This is nonsense no matter what dates you're speaking of. In effect it claims that all rocks that indicate life were created at the same time. So this is definitely a bad choice.

The rock layers must have formed at different times because they contain two different biozones. * This is technically incorrect since it assumes that all biozones represent an unique period of time which is incorrect. However, since the biozones represented by the presence of Trilobites and Ammonites don't overlap, it is true that these these rock layers were formed at different times. I would have preferred if this option said "non overlapping biozones". But on the balance, I'd consider this option to be true, so it should be selected.

The rock layer containing the trilobites must have formed before the one containing the ammonites. * This is definitely true since the last Trilobite died about 3 million years before the first Ammonite lived. So this is a correct choice.

The rock layer containing the trilobites must have formed after the one containing the ammonites.

* This is the opposite of the previous option. And since the previous option was true, this option must be false. So this is a bad choice

The West India Docks and Blackwall Basin, c. 1956.

An aerial view across the West India Docks towards Blackwall Basin, the original non-tidal entrance to the docks. To the right of the picture, the entrance lock from Blackwall Reach to the South Dock is clearly visible. In 1926, this dock (formerly the City Canal) was connected to the two northern import and export docks and to the adjacent Millwall Docks. Finally, in the far distance beyond Blackwall Point, lies the Victoria Dock, first of the mighty Royal Docks complex.

The West India Docks in 2001

The docks are now dominated by the Canary Wharf estate which extends over 86 acres of what was formerly the West India Docks. Until the closure of the docks in 1980, hundreds of dockers would have worked there. Now, thousands of office staff are employed on the estate. Although most of the dock area has been filled in, the Blackwall Basin remains, as does the entrance to the old South Dock and much of the dock water itself.

The Royal Group of Docks, c. 1930.

Located in the bend of the river between Bugsby's Reach and Gallions Reach, the Royal Docks group formed the largest area of continuous dock water in the world. A vessel travelling from east to west across these docks would have passed through three miles of water crowded with ships, tugs and lighters. This aerial view of the docks clearly shows the extent of the complex, including the huge entrance locks at Gallions Reach.

The 31 acres of water at the docks were later used by ships from the Union Castle Line, Ellerman Line, Blue Star Line and Ben Line. In the 1920s, new facilities were built for the handling of frozen meat. The export dock was badly bombed during the Second World War and filled-in. The docks closed in 1967.
