Answer:
Explanation:
Through food chains, the carbon that is in plants moves to the animals that eat them. Animals that eat other animals get the carbon from their food too. Carbon moves from plants and animals to soils. When plants and animals die, their bodies, wood and leaves decays bringing the carbon into the ground.
Answer:
Explanation:
To convert from moles to grams, we must find the molar mass.
1. Molar Mass
First, identify the elements in the compound. K₂CO₃ It has potassium, carbon, and oxygen. Find these elements and their masses on the Periodic Table.
- K: 39.098 g/mol
- C: 12.011 g/mol
- O: 15.999 g/mol
Note the subscript of 2 after K and 3 after O. We must multiply oxygen's molar mass by 2, then oxygen's by 3, and add carbon.
- 2(39.098 g/mol) + 3(15.999 g/mol) + 12.011 g/mol= 138.204 g/mol
2. Convert Moles to Grams
Use the molar mass as a fraction.
Multiply by the given number of moles: 6.2
There are <u>856.8648 grams</u> of potassium carbonate in 6.2 moles.
Answer:
The answer is A
Explanation:
I checked on a temperature converter calculator.
Answer:
. All redox reactions occur with a simultaneous change in the oxidation numbers of some atoms. At least two elements must change their oxidation numbers. When an oxidation number of an atom is increased in the course of a redox reaction, that atom is being oxidized
Explanation:
Answer:
H20
Explanation:
Water is a transparent, tasteless, odorless, and nearly colorless chemical substance, which is the main constituent of Earth's streams, lakes, and oceans, and the fluids of most living organisms. It is vital for all known forms of life, even though it provides no calories or organic nutrients
