atoms 
Explanation: First, using stoichiometry, we must convert this from grams to moles, then from moles to atoms.
1. For the first step, we should also look at the periodic table to find the molar mass of the compound, then use that as the denominator.
2. Now that it is converted to moles, we must convert it to atoms by multiplying it by Avogadro's number.
With this information, we know that there are 
total atoms in 0.680 grams 
.
I hope this helps! Pls give brainliest!! :)
Answer:
1)This type of reaction is called thermal decomposition . Copper carbonate is green and copper oxide is black. You can see a colour change from green to black during the reaction. The carbon dioxide produced can be detected using limewater, which turns milky. 2) The extremely low pressure of the partial vacuum inside the can made it possible for the pressure of the air outside the can to crush it. A can is crushed when the pressure outside is greater than the pressure inside, and the pressure difference is greater than the can is able to withstand.

Answer:
- Volatile organic compounds
- secondary pollutants or photochemical substances
- Air Quality
- Air pollution
- Aerosols
Explanation:
Volatile organic compounds are the organic chemicals that get easily vaporized in air.
The secondary chemicals or the secondary pollutants are the photochemical substances that are formed in the presence of sunlight.
The amount of gases and small particles present in the atmosphere, responsible for influencing ecosystem and the wellness of human beings is known as the Air Quality
Air pollution refers to the high concentrations of gases or small particles that are present in the atmosphere, which can cause harm to the humans and other living organisms and structures established by humans.
Aerosols are the tiny particles present in liquid or solid state, that are suspended in air.
It’s the elephant because it’s bigger in size and it covers more surface area. The mouse is smaller in size. The elephant would be the answer
