A 60.0 g sample of chromium at 82.0°C (specific heat for chromium is 0.11 J/g°C) was placed in 80.0 g of water. Assume there is

no loss of heat to the environment. What is the temperature of the water and the chromium? The water's initial temperature was 24.0°C.

The temperature of the water and the chromium : 25.122 ° C  

<h3>Further explanation  </h3>

The law of conservation of energy can be applied to heat changes, i.e. the heat received / absorbed is the same as the heat released  

Q in(gained) = Q out (lost)

Heat can be calculated using the formula:  

Q = mc∆T  

Q = heat, J  

m = mass, g  

c = specific heat, joules / g ° C  

∆T = temperature difference, ° C / K  

Q Chromium= Q water

\tt 60\times 0.11\times (82-t)=80\times 4.18\times (t-24)\\\\541.2-6.6t=334.4t-8025.6\\\\341t=8566.8\\\\t=25.122^oC

Arrange the following compounds from left to right in order of increasing percentage by mass of hydrogen: a) H2O, b) C12H26, c)
Nuetrik [128]

Answer:

(A) N4H6  (B) H2O  (C) LiH  (D) C12H26

Explanation:

The given compounds have been arranged  from left to right in order of increasing percentage by mass of hydrogen.

The percent by mass of hydrogen can be calculated by mass of hydrogen in that compound divided by total mass of that compound and finally multiplying the result with 100 to obtain the required percentage.
