Answer:
The carbon cycle
Or
Carbon moves from living things to the atmosphere. Each time you exhale, you are releasing carbon dioxide gas (CO2) into the atmosphere. Animals and plants get rid of carbon dioxide gas through a process called respiration. Carbon moves from fossil fuels to the atmosphere when fuels are burned.
I think that the answer is 0.49
The answer should be (4) they are negative subatomic particles and are found surrounding the nucleus. The nucleus is formed by neutrons and protons. Neutrons are neutral and protons are positive.
The gram-formula mass of Sm is 150.36 u, and the gram-formula mass of O is 15.999 u, so the gram-formula mass of SmO is about 150.36+15.999 = 160.36 g/mol.
So, there are about (9.30 * 10^-3)(160.36)=1.49 grams
1- KNO3 and H2SO4. electrolyte is a liquid that consists of ions, which decomposes during the process of electrolysis, electrolytes will dissolve in liquids, like water. Since KNO3 and H2SO4 both dissolve in water, they are the right answer
