A buffer solution of pH value 4 is to be prepared, using CH_(3)COOH and CH_(3)COONa .How much amount of sodium acetate is to be added to 1.0L of M//10 acetic acid? (K_(a) = 2.0 xx 10^(-5))

0.1mol of CH_(3)NH_(2) (K_(b) = 5 xx 10^(-4)) is mixed with 0.08mol of HCI and diluted to 1L . Which statement is correct?

List two most common STDs.

Most common bacterial STD is:

The equilibrium constant for the reaction: CH_(3)COOH(l) + C_(2)H_(5)OH(l) iff CH_(3)COOC_(2)H_(5)(l)+ H_(2)O(l) has been found to be equal to 4 at 25^(@)C . Calcuclate the free energy chnage for the reaction.

When 20g of a compound (A) (M.F. = C_(4)H_(10)O_(4)) reacts with excess of CH_(3)MgBr , 14.6 L of CH_(4) is obtained at STP. What is structure formula of (A) ?

In the reaction, CH_(3)COOHoverset(L(A)H_(4))rarrAoverset(PC_(5))rarrBoverset(A//C.NOH)rarrC, the product C is :-
