only reactants are present
If equllibrium constant is greater than 10^3 then product
predominates
If equllibrium constant is greater than 10^ -3 then reactant predominates
in between 10^3 and 10^-3 the reaction is in equllibrium
and we see that the above value is 10^-31, it is very small so the answer is reactants are presents

Answer:
0.077M is the concentration of the hydroxyl ion
Explanation:
If 7.35 cm3 of this base is take and diluted to 147 cm3, then what is the concentration of the hydroxyl ion?
Use the dilution equation:
M1V1 = M2V2
M1 * 147cm³ = 1.5 M * 7.35 cm³
M1 = 1.5 M * 7.35 cm³ / 147 cm³
M1 = 0.077 M
<h3> 0.077M is the concentration of the hydroxyl ion</h3>
How many moles of hydroxyl ion are there in the 7.35 cm3?
1000 cm³ contains 1.5 mol OH- ions
7.35 cm³ contains : 7.35 cm³ / 1000 cm³ *1.5 mol
= 0.011025 mol
<h3>Answer correct to 2 significant digits = 0.011 mol OH- ions.</h3>
