31.79 g Cu / 63.5 g/mol Cu ---> 0.5
0.5 * (2/1) ---> 1
1 * 107.9 g/mol Ag
107.9 grams
Answer is: 0.0213M.
Reaction: N₂O₄ (g) ↔ 2NO₂ (g).
Kc = 0,211 at <span>100°C.
Kc - </span><span>equilibrium constant.
</span>c (N₂O₄) = [N₂O₄] = 0,00251M.
c (NO₂) = [NO₂] = ?
Kc = [NO₂]² / [N₂O₄]
[NO₂]² = Kc · [N₂O₄]
[NO₂] = √(Kc · [N₂O₄<span>]) </span>
[NO₂] = √(0.211 · <span>0.00215M) </span>
[NO₂] = 0.0213M.
Answer:
A mixture is just a combination of things, like air (made up of different but distinct gasses), or toothpaste, where compounds are physically mixed together but stay fundamentally what they started as. If there is a chemical change, like hydrogen and chlorine gas reacting to form hydrochloride acid, then it is known as a new compound.
Answer:
3Li2CO3 + Ca3(PO4)2 → 2Li3PO4 + 3CaCO3
3,1,2,3 are the coefficients.
Explanation:
Li2CO3 + Ca3(PO4)2 → Li3PO4 + CaCO3
Balanced equation is :
3Li2CO3 + Ca3(PO4)2 → 2Li3PO4 + 3CaCO3
Explanation:
IR (infrared) spectroscopy theory is based on the concept that the molecules tend to absorb some specific amount of the frequencies of light which are characteristic of corresponding structure of molecules. These energies are reliant on shape of molecular surfaces, associated vibration coupling, and mass corresponding to atoms.
It is used to detect the type of the functional group present in the organic compound.
