The 4 types of air masses are polar, tropical, continental and maritime. Their classification depends on their location where they are formed.
The solubility of a gas (Sgas) is directly proportional to its partial pressure (Pgas). what pressure of carbon-dioxide is required to keep the carbon dioxide concentration in a bottle of club soda at 0.12 M at 25 degrees Celsius ? 0.12 M = 3.4 x 10^-2 (Pgas?)

Answer: 10 grams of Hydrogen gas will be produced theoretically.
Explanation: The equation for the reaction between zinc metal and hydrochloric acid is:
As HCl is present in excess, therefore limiting reagent is Zinc metal as it limits the formation of product.
By stoichiometry,
1 mole of Zinc metal produces 1 mole of Hydrogen gas, therefore
Amount of Hydrogen gas produced can be calculated by:
Molar mass of Hydrogen = 2 g/mol
Mass of hydrogen gas produced = (5 moles )× (2 g/mol)
Mass of hydrogen gas produced = 10 grams
