Answer:
5.7
Explanation:
The pH can be calculated by:
pH = -log[H⁺]
Where [H⁺] is the concentration of hydrogen ions. The pH is a way to identify if the solution is an acid or a base. When pH is equal to 7, the solution is neutral, when it is less than 7, it is acid, and when it is larger than 7, it's a base.
So, for the acid solution given, [H⁺] = 2.0x10⁻⁶ M
pH = -log(2.0x10⁻⁶)
pH = 5.7
Use stoichiometry to solve this problem. We know that 1.00 mole of CuO is (about) 45g, and we also know that the ratio of CuO to Cu is 1:1, meaning that 1 mole of CuO can be used to produce 1 mole of Cu. Look up the molar mass of Cu on the periodic table to see the answer.
The overall process of cellular respiration is to use the energy or ATP in the sugars in your body, to supply your cells with with oxygen and water.
