Question is in coffee cup, color meter 50 ml of 0 .1 molar ag no3 and 50 ml of 0 .1 molar hcl or mixed to yield the following reaction.
00:10
Okay, and the two solutions were kept at the 22 .6 degree centigrade and the other temperature, 23 .4 degree centigrade.
00:19
Heat is, so what will be the heat? okay, so reaction is given agno3 plus hcl.
00:31
Plus hcl that will give agcl plus hno3.
00:38
So first we have to calculate mole.
00:40
Mole is equal to modality multiply volume.
00:44
So modality is given 0 .1, multiply 50 divided by 1000.
00:49
Mole of the hcl 50 divided by 1000 multiply 0 .1.
00:58
So what value will be equal to 5 multiplied 10, and it will remain same here also it is the value of the mole yes or no so now what we can do here we have to calculate heat heat is equal to mc t2 minus t1 correct so mass of the solution is given 100 ground and specific heat capacity also given first we will calculate q 100 multiply 4 .18 t2 minus t1 final temperature 23 .4 minus 22 .6 correct? so what value will be come out here? multiply 418.
02:01
It will be equal to 334 .4 joule.
02:07
In the kilojoule it will be what? point 334 kilojoule...
