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.
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.

In circle C shown below, a tangent has been drawn at point A. If m CBA 28 then explain why the measure of DAB must equal 62.
Answer:
The solution is shown below
Explanation:
From the image attached:
Line BC and line AC are the radii of the circle, therefore BC = AC.
Since BC = AC, the triangle ABC is an isosceles triangle with m∠CBA = m∠CAB = 28°
Also line ED is a tangent to circle C. From the circle theorems, a tangent to a circle is at right angle to the circle radius at point of contact. Since AC is a radii, ∠EAC = 90°
Therefore:
∠DAB + ∠EAC + m∠CAB = 180° (sum of angles on a straight line)
∠DAB = 180° - ∠EAC - m∠CAB
∠DAB = 180 - 90 - 28 = 62
∠DAB = 62°

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.
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.
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.
