Calculate the heat change involved when 2.00 L of water is heated from 20.0/C to 99.7/C in
Pani-rosa [81]

Answer:

666,480 Joules or 669.48 kJ

Explanation:

We are given;

  • Volume of water as 2.0L or 2000 ml

but, density of water is 1 g/ml

  • Therefore, mass of water is 2000 g
  • Initial temperature as 20 °C
  • Final temperature as 99.7° C

Required to determine the heat change

We know that ;

Heat change = Mass × Temperature change × specific heat

In this case;

Specific heat of water is 4.2 J/g°C

Temperature change is 79.7 °C

Therefore;

Heat change = 2000 g × 79.7 °C × 4.2 J/g°C

                      = 669,480 Joules 0r 669.48 kJ

Thus, the heat change involved is 666,480 Joules or 669.48 kJ

tino4ka555 [31]
The  %  composition  of  each  element  is  calculated  as   follows

=  mass   of  the  element/total  mass   x100

total  mass=  73.5+4.2+72.3=150
%  composition  of  C  =  73.5/150 x100=49%

%  composition  of  H= 4.2/150 x100=  2.8%

%composition  of  Cl=  72.3/150  x100=  48.2%
