Ammonium is NH₄⁺ and Carbonate is CO₃⁻² => Ammonium Carbonate is (NH₄)₂CO₃
Okay so molar mass is given, no. of moles is given and we have to calculate the weight or mass of the compound in gram.
the formula we will use here is= n=W/M
where n is no. of moles ,w is weight in gram which we have to find and M is molar mass or formula weight which is given.
so W=n x M
use this formula you'll get the answer
Answer:
it is false
Explanation:
it goes in different ways not in order
AT 15°
The rate of diffusion of a gas is directly proportional to the absolute temperature. At lower temperature the gas particles have less kinetic energy than at higher temperature. This makes the particles travel faster at higher temperature than lower temperature.
Answer:
Column A Column B
1. CaS Calcium Sulfide
2. CaSO₄ Calcium sulfate
3. CaSO₃ Calcium sulfite
Explanation:
1) Calcium sulfide is a compound formed between calcium, Ca, and sulfur, S, with a chemical formula of CaS. It forms cubic crystals similar to rock salt, and smells like rotten eggs
2) Calcium sulfate is a chemical compound consisting of calcium, Ca, and sulfate SO₄. It is found in nature in the hydrated form as the mineral gypsum
3)Calcium sulfite is a chemical compound formed between calcium, Ca and sulfite, SO₃ used to treat water and preserve food.
