0.18 g of a divalent metal was completely dissolved in 250 cc of acid
solution containing 4.9 g H2SO4 per liter. 50 cc of the
residual acid solution required 20 cc of N/10 alkali for
complete neutralization. Calculate the atomic weight of
metal.
39.
Ans: 36​

Cause its being chemically applied?

Answerδh > 0explanationc₆h₆  (s)  → c₆h₆ (l)if you are changing it from a solid to a liquid, you are pretty much melting the solid. this requires heat energy. therefore, the reaction is endothermic (takes in energy); the system enthalpy increases as the reaction proceeds: δh > 0.

If this is a true or galse then its true but if not then what is the question?
