Answer: 0.8541 grams of HCl will be required.
Explanation: Moles can be calculated by using the formula:

Given mass of
= 0.610 g
Molar mass of
= 78 g/mol

Number of moles of
= 0.0078 moles
The reaction between
and HCl is a type of neutralization reaction because here acid and base are reacting to form an salt and also releases water.
Chemical equation for the above reaction follows:

By Stoichiometry,
1 mole of
reacts with 3 moles of HCl
So, 0.0078 moles of
will react with
= 0.0234 moles
Mass of HCl is calculated by using the mole formula, we get
Molar mass of HCl = 36.5 g/mol
Putting values in the equation, we get
Mass of HCl required will be = 0.8541 grams
Effects of changes in volume in a reversible reaction in a chemical equilibrium can be predicted using Le Chatelier's Principle. I think this might be the answer, I hope it helps.
They are both (polyatomic) ions.
540 nm is the answer ! can you help me out please ? it is a science question add me and message me :)
The answer is B have a good day
