The pH would be 3.16 because the formula for finding the pH from a H± ion is pH = -log [H±]

So with that formula, you first have to substitute the H± with your numbers which in this case is 6.9 × 10^-4.

It should like this:

pH = -log (6.9 × 10^-4)

And lastly, just calculate.

pH = 3.16

Hope that helps, do let me know if you need more help in understanding this!

The table shows a chemical equation and the dimensional analysis used by a student to calculate the number of moles of Ba3N2 req

UNO [17]

This problem is providing the chemical reaction whereby barium nitride reacts with water to produce barium hydroxide and ammonia, so the number of moles of barium nitride are required in order to produce 8.3 moles of ammonia. It asks for us to evaluate the student's setup, so we conclude the answer is C. "1 mol of NH3 should be replaced with 2 mol of NH3", according to:

<h3>Mole ratios:</h3>

In chemistry, stoichiometric calculations are used to figure out the moles or mass of a substance, given information about another one in the reaction. In this case, for the given chemical equation:

$Ba_3N_2 + 6H_2O \rightarrow 3Ba(OH)_2 + 2NH_3$
