Answer:
= 4.37*10^-9 M
Explanation:
We know that;
pH + pOH = 14
Therefore;
pH = 14 - pOH
Which means; pH = 14 - 5.64
= 8.36
But;
pH = -log[H3O+]
Thus;
8.36 = -log[H3O+]
[H3O+] = 10^(-8.36)
= 4.37*10^-9 M
A method of converting one unit of measurement to another, like liters to milliliters.
<u>Answer:</u> The correct answer is Option A.
<u>Explanation:</u>
Mole ratio is defined as the ratio between the stoichiometric coefficients of the molecules present in the chemical reaction.
For the given balanced chemical equation:

By Stoichiometry of the reaction:
3 moles of iron metal reacts with 4 moles of water to produce 1 mole of iron oxide and 4 moles of hydrogen gas.
The mole ratio of 
Hence, the correct answer is Option A.
