Answer:

A: leaving a copper penny in vinegar until it turns green

Explanation:

The corrosion is from oxidation -- a chemical reaction between the metal and oxygen, water, and carbon dioxide in the air. Rust is the term used to describe this process when it happens to iron instead of other metals. I also took it on E2020. If you need further explanation, please comment below.

A mole is equal to 6.02 x 10²³, just like a dozen is equal to 12. So if you have a mole of carbon atoms, you have 6.02 x 10²³ ca

You must perform stoichiometry! always divide by what you already have (this will make since in a moment)

5.2g Carbon | 1 mole/12.01g/mole | 6.02 x 10^23 atoms/1 mole | = atoms in Carbon

above is the basic stoichiometry set up but your calculation should be (5.2g/12.01g) x (6.02 x 10^23) = 2.61 x 10^23 atoms

The 2 types of mechanical weathering are .....
1) * Temperature Change
-Temperature change makes rocks contract and expand
-Also one of the important cause of mechanical weathering.
2) * Abrasion
-Abrasion is a process in which an external force
Example: water movement or gravity which causes rock materials grind (reduce <<< synonyms) which can break apart the outer layers of affected rocks.*PLEASE GIVE THIS A THANKS :) :D xD AND ALSO THE BRAINIST ANSWER PREETTY PLEASEEEEEEEE, DON'T YOU EVER FEEL LIKE YOUR GOOOOING TO GIVE ME THE BRAINIEST ANSWER/CROWN??? xD

The specific heat of water is 4.18 J/(g⋅∘<br> c. Calculate the molar heat capacity of water.
Xelga [282]

We are given that the specific heat of water is 4.18 J / g °C. We know that the molar mass of water is 18.02 g/mol, therefore the molar heat capacity is:

 

molar heat capacity = (4.18 J / g °C) * 18.02 g / mol

<span>molar heat capacity = 75.32 J / mol °C</span>
