Answer:
The hydrogen ion concentration in a solution, [H+], in mol L-1, can be calculated if the pH of the solution is known.
pH is defined as the negative logarithm (to base 10) of the hydrogen ion concentration in mol L-1 pH = -log10[H+] ...
[H+] in mol L-1 can be calculated using the equation (formula): [H+] = 10-pH
reactants because it had other chemicals, when more are mixed it will be more stronger.
It is the correct answer
Answer:
Mass of Oxygen = 32 grams
Explanation:
Given:
Mass of water = 36 grams
Mass of Hydrogen = 4 grams
Find:
Mass of Oxygen
Computation:
Using Law of Conservation of mass
Mass of water = Mass of Hydrogen + Mass of Oxygen
36 grams = 4 grams + Mass of Oxygen
Mass of Oxygen = 32 grams
