Answer:
Heat transferred, Q = 1542.42 J
Explanation:
Given that,
Mass of water, m = 30 grams
Initial temperature,
Final temperature,
We need to find the energy transferred. The energy transferred is given by :
c is specific heat of water, c = 4.18 J/g °C
So,
So, 1542.42 J of energy is transferred.
Answer:
Explanation:
first write the equilibrium equaion ,
⇄
assuming degree of dissociation =1/10;
and initial concentraion of =c;
At equlibrium ;
concentration of
is very small so
can be neglected
and equation is;
=
composiion ;
