To find solubility, we need calculate how much potassium sulfate will be dissolved at 100 g of water.
12 g potassium sulfate ------ 75 g water
x g potassium sulfate --------100 g water
x=12*100/75 = 16g
So, solubility of potassium sulfate at 60⁰ C is 16 g potassium sulfate per 100 g of water.
Answer:
x is CO2
y is H2O
Explanation:
An organic compound that contains carbon and hydrogen is called a hydrocarbon.
When a hydrocarbon is burnt in air (combustion) only two products are obtained; carbon dioxide and water. The carbon dioxide comes from the carbon component of the molecule while the water comes from the hydrogen component of the molecule.
Therefore, for a hydrocarbon CxHy we obtain; xCO2 and (x + 1)H2O as products.
