crushing up a sugar cube before putting it into your coffee

adding bath salts to a tub full of hot water

adding protein mix and milk to a shaker bottle and shaking it

Explanation:

The action of crushing sugar into fine particles enhances solute-solvent interaction and increases the solubility of the solute in the solvent.

Adding bath salts to a bath full of hot water enhances solubility due to the increase in temperature and large amount of solvent. Increase in temperature and increase in amount of solvent increases rate of dissolution of solute in a solvent.

Shaking ensures proper dissolution and homogeneity of a solution.

calculate how many grams of ammonia can be produced from 4.21 grams of

n2 + 3h2 = 2nh3

my answer:

25.0g n2 x (1 mol/ 28.0gn2) x (2 mol nh3/ 1 mol n2) x (17.0g nh3/ 1 molnh3) = 30.36g n2

25.0g h2 x (1 mol h2/ 2.00g h2) x (2 mol nh3/ 3 mol h2) x (17.0g nh3/ 1 mol nh3) = 141.67g h2

lr = n2
