What is the maximum amount of kcl that can dissolve in 200g of water?

1 answer:

8 0

The solubility of potassium chloride in at room temperature is approximately 34 g per 100 g of water. Therefore, the maximum amount that could be dissolved would be 34/100 ( 200) = 68 g of KCl. When more than this amount is added, excess potassium would not dissolve forming crystals in the solution.

Answer is: 3,3 mol of <span>nitrous oxide gas is produced in this chemical reaction.
</span>Chemical reaction: N₂ + O₂ → 2NO.
n(N₂) = 1,65 mol.
n(NO) = ?
from reaction n(N₂) : n(NO) = 1 : 2.
1,65 mol : n(NO) = 1 : 2.
n(NO) = 3,3 mol.
n - amount of substance.

Kazeer [188]

Answer:

$2H_2O\rightarrow 2H_2+O_2$

Explanation:

Hello there!

In this case, for the reaction by which water is decomposed to molecular hydrogen and oxygen:

$H_2O\rightarrow H_2+O_2$

It is necessary to perform the inspection balance process since there is a dissimilar number of atoms of oxygen on both sides; therefore, by putting a 2 on water we balance oxygen:

$2H_2O\rightarrow H_2+O_2$

But now, there are four hydrogens on the left; therefore, we put a 2 on hydrogen to finally balance it:

$2H_2O\rightarrow 2H_2+O_2$

And obviously, the coefficient in oxygen is an unwritten 1.

Best regards!
