8.5 x 10-3 J/g·°C


8.5 x 100 J/g·°C


8.5 x 102 J/g·°C


1.2 x 10−1 J/g·°C

Answer 1

Delta Q =M S delta T
S= Delta Q /M Delta T
put the values of
Delata Q , Delta T and Delta Q
and find the S

Answer 2

I am not sure that was English lol

Answer 3

can you do caluclate now

Answer 7

I got 0.11011765

Answer 8

0.52/61.2 u should get
=0.0849 u get

Answer 9

0.00849

Answer 10

its unit is KJ/g °C

Answer 11

yes, my problem is converting that to one of the equations that the teacher gave as choices.

Answer 12

it becomes 8.5 J/g °C
but which not in ur choice LOL
some thing mistake is their in ur options

Answer 13

hmm that is what we have been thinking that the teacher is not being correct... I think the second best option would be 8.5 x 10^0 g c?

Answer 14

yaaa is it 10^) LOL
u have not mentioned here

Answer 15

yeah I should have noticed that mistake sorry.. so ready for the next one?? :+D

Answer 16

LOL:) OK
