Dear students, it is an acid -based neutralization reaction where the volumes of acid basis are 93 .2 and 46 .6 ml.
00:11
Therefore, on mixing volume of the mixture, total volume of the mixture is 139 .8 mill.
00:17
Density of the mixture is 1 gram per ml.
00:20
Therefore, we can write here 139 .8 gram also, because density is 1 gram per ml.
00:27
Specific heat of the solution is 4 .18 at change in temperature, before mixing temperature is 21 .25 and after mixing or after neutralization, it is 31 .7.
00:37
So change in temperature is 9 .45 degree.
00:40
So let us calculate the heat evolved 2 equal to ms delta theta, where m is the mass of the mixture that is 139 .8, multiplied by specific it is 4 .18, multiplied by change in temperature is 9 .4 .4 .4 .4.
00:59
So, we are getting here 552255 on simplification are getting 552 .522.
01:13
So this is the amount of heat evolved here...
