Answer:
Explanation:
The temperature and amount of gas are constant, so we can use Boyle’s Law.

Answer:
No
Explanation:
I do not think you will get a neural solution. A neutral solution is one formed when a basic substance reacts with an acidic substance. While ammonia is a weak base, baking soda is also a carbonate which makes it basic in nature too.
Hence, by combining both, I do not think we will get a neutral solution as they are both basic substances
Answer:
Atoms: <em>they are tiny particles that are the basic building blocks of any substance. The atoms are themselves made up of even smaller particles-protons, neutrons and electrons. </em>
Molecules: <em>it is the smallest unit of matter, which can exist independently. A molecule is formed when two or more atoms combine together.</em>

Answer:
17.9 Moles
Explanation:
In the one-kilogram iron weight there are 1.08·1025 atoms, which corresponds to the chemical amount of approximately 17.9 moles of atoms
To find the number of moles, determine the molar mass of iron. Then divide the given mass by its molar mass, or multiply the given mass by the reciprocal of the molar mass, which is more common.
Explanation:
Just like an independent variable, a dependent variable is exactly what it sounds like. It is something that depends on other factors. For example, a test score could be a dependent variable because it could change depending on several factors such as how much you studied, how much sleep you got the night before you took the test, or even how hungry you were when you took it. Usually when you are looking for a relationship between two things you are trying to find out what makes the dependent variable change the way it does.
