Answer:
The volume of stock solution needed to make the solution is 1875 ml
Explanation:
The parameters given are;
The volume of 75 M solution of H₂SO₄ = 400 ml
The concentration of stock solution = 16.0 M
Number moles per liter of stock solution = 16 moles
Number of moles in required 400 ml solution = 0.4×75 = 30 M
Volume of stock solution that contains 30 M = 30/16×1 = 1.875 l
The volume of stock solution that is required = 1875 ml
Answer : The number of sodium ions is equal to the number of formula units of salt.
Explanation : In the given reaction of NaCl the statement which describes it the best is that the number of sodium ions is found to be same along with the formula units in the product side.
+ 
----> NaCl.
Its clear from the equation that one mole of Na and one mole of Cl combines together to give the product, which is one mole of NaCl. The number of ions on both the sides are equal.
Answer:
ΔG=ΔG0+RTlnQ where Q is the ratio of concentrations (or activities) of the products divided by the reactants. Under standard conditions Q=1 and ΔG=ΔG0 . Under equilibrium conditions, Q=K and ΔG=0 so ΔG0=−RTlnK . Then calculate the ΔH and ΔS for the reaction and the rest of the procedure is unchanged.
