Take a long time
Explanation:
Geology is defined as a science mostly concerned with the study of the history of the earth as recorded in different rocks formations.
Geologic processes are events that occur on a geological timescale which may span across many centuries.
The four major geologic process are known to include; impact cratering, volcanism, tectonics, and erosion.
Answer:
true
Explanation:
To find the mass of substance the equation is
[Container and Substance] + [Container] = [Substance]
True
False
Answer: FALSE
In order to find the mass of a substance you need to measure the container with the substance in it, and then take a second measurement with the container empty. You would then subtract the two measurements to find the total mass of the substance, you would not add as stated in the question.

does a liquid have a shape??
Answer:
Yes, just not a fixed shape.
Explanation:
A liquid take shape of whatever is containing but that does not fix it. As long as it is being contained it retains it's shape, yet the second you release it from it's containment it becomes the shape and can take the physical properies of whatever it is contained by next.

If you have difficulty removing a ring from your finger, you usually lubricate your finger with oil or soap
Why, in most cases, does this procedure work
Answer:
Because oil reduces the friction between the surface of your ring and your finger.
Thus it helps you to remove your ring easily

calcium oxide (Cao) and carbon dioxide (CO2). If 100 g of
calcium carbonate is allowed to decompose, 56 g of calcium
oxide is produced. What mass of carbon dioxide is produced
by the decomposition?
g
Answer:
Explanation:
CaCO3 → CO2 + CaO
depending on the conservation of mass
mass of the product = mass of the reactant
100 g = ( X + 56 )
mass of CO2 = 100 - 56
= 44 g
Answer:
44g

3. Describe air using the terms: mixture, atoms, and molecules.
I
Air is a mixture of gases. Air is composed of molecules such as oxygen, nitrogen and carbon dioxide. Air also contains atoms of noble gases such as neon, argon etc.
Air is composed of 21% molecular oxygen and 78% molecular nitrogen. Also, there is about 0.03% of carbon dioxide molecules in air.
Air is generally defined as a mixture of gases owing to the number of gaseous substances that compose air.
Also, there is a trace amount of noble gases which largely exists as monoatomic species in air.

If a cube has a volume of 25.0 mL, what mass, in grams, would it have to have to
be made of gold? Gold has a density of 19.3 g/mL. (Answer only the number with
the correct number of sigfigs) *
Answer:
482.5 grams
Explanation:
Given that,
Volume of a cube is 25 mL
The density of gold is 19.3 g/mL
We need to find the mass of the gold cube. We know that density is equal to the mass per unit volume. So,
[tex]d=\dfrac{m}{V}\\\\m=d\times V\\\\m=19.3\ g/mL\times 25\ mL\\\\m=482.5\ g[/tex]
So, the mass of the gold cube is 482.5 grams.

Which actions are part of a system of methodical tests and refinements specific to technological design? 1 documenting, tinkering, testing 2 tinkering, presenting, testing 3 testing, documenting, pr esenting 4 presenting, tinkering, testing
Answer:
1. documenting, tinkering, testing
Explanation:
Technological design is defined as the process of study, design and development of new technologies.
There are some action in the methodical tests and refinements specific to technological design include documenting, tinkering, testing.
Documenting includes collecting all the information about the design and develop the product, tinkering involves repairing or adjust the issues found in the development, and testing helps to evaluate if the product is ready to work as it is supposed to.
Hence, the correct answer is "1."

Atomic elements exist with a single atom as their basic unit. H2, F2, and P4 are some examples of atomic elements. H, F, and P are some examples of molecular elements. Atomic elements have more than one atom in their basic unit. H, F, and P are some examples of atomic elements. H2, F2, and P4 are some examples of molecular elements. Molecular elements have more than one atom in their basic unit.
Answer:
Atomic elements exist with a single atom as their basic unit.
H, F, and P are some examples of atomic elements.
H2, F2, and P4 are some examples of molecular elements.
Molecular elements have more than one atom in their basic unit.
Explanation:
Atomic element exists as the smallest particle of an element that can take part in a chemical reaction. They exist with a single atom as their basic unit. The atomic number of an element is the number of protons present in the atomic nucleus of the element. Atomic elements are usually monoatomic such as H, F and P.
Molecular elements are the smallest particle that are capable of independent existence and still retains the chemical properties of those substances. They are capable of independent existence because they are diatomic. The combination of atoms of the same type produces a molecule of an element such as H₂, F₂, and P₂.

You have just won a block of pure 24-carat gold. Have you just procured an element, compound, or mixture?
Answer:
element
Explanation:
24 carat gold is an example of element.
What is element?A fundamental object that is difficult to divide into smaller pieces is known as an element. An element is a substance that cannot be broken down by non-nuclear reactions in chemistry and physics.
The atomic number, or quantity of protons in an element's nucleus, is used to categorize each element. Isotopes can be produced depending on the amount of neutrons in the nucleus.
Isotopes will have different physical properties although sharing the same chemical ones. Deuterium contains one proton and one neutron, tritium has one proton and two neutrons, but normal hydrogen has one proton and no neutrons.
Therefore, 24 carat gold is an example of element.
