Answer:
The 2 in the formula means that, there are 2 phosphate anions that forms the salt.
Explanation:
Magnesium phosphate is a ionic salt.
The formula indicates that 3 moles of Mg and 2 moles of anion phosphate are contained in 1 mol of compound.
3Mg²⁺ + 2PO₄⁻³ → Mg₃(PO₄)₂
The phosphate anion comes from phosphoric acid and it is generated when the acid loses the 3 protons.
H₃PO₄ → 3H⁺ + PO₄⁻³
Phosphate has a negative charge of -3, so when it bond to magnesium, which has a charge of +2, there must be 3 magnesium and 2 phosphate to make a global charge +6 -6 in the ions
Answer: Option (e) is the correct answer.
Explanation:
An equilibrium reaction is defined as the reaction where rate of forward reaction will be equal to the rate of backward reaction.
For example, 
So, here amount of reactants that is, nitrogen gas and hydrogen gas will be constant along with constant amount of formation of product that is, ammonia here.
In an equilibrium reaction there is presence of both reactants and products and hence, both reactants and products constitute the system.
Thus, we can conclude that all the given statements are true.
