You used a calorimeter in the heat transfer lab. Explain how the calorimeter works, and how to calculate the heat given off or a
Butoxors [25]
A calorimeter contains reactants and a substance to absorb the heat absorbed. The initial temperature (before the reaction) of the heat absorbent is measured and then the final temperature (after the reaction) is also measured. The absorbent's specific heat capacity and mass are also known. Given all of this data, the equation:
Q = mcΔT

A student has 100. mL of 0.400 M CuSO4 (aq) and is asked to make 100. mL of 0.150 M CuSO4 (aq) for a spectrophotometry experimen
GenaCL600 [577]

Answer:

We have to take 37.5 mL of a 0.400 M solution

Explanation:

Step 1: Data given

Stock volume = 100 mL  = 0.100L

Stock concentration 0.400 M

Volume of solution he wants to make = 100 mL = 0.100L

Concentration of solution he wants to make = 0.150 M

Step 2: Calculate the volume of 0.400 M CuSO4 needed

C1*V1 = C2*V2

⇒with C1 = the stock concentration = 0.400M

⇒with V1 = the volume of the stock = TO BE DETERMINED

⇒with C2 = the concentration of the solution he wants to make = 0.150 M

⇒with V2 = the volume of the solution made = 0.100 L

0.400 M * V1 = 0.150M * 0.100L

V1 = (0.150M*0.100L) / 0.400 M

V1 = 0.0375 L = 37.5 mL

We have to take 37.5 mL of a 0.400 M solution

Data

Chemical reaction

                   (NH₄)₂CO₃  ⇒   NH₃  +  CO₂  + H₂O

               Reactants    Elements     Products

                      2            Nitrogen             1

                       1            Carbon                1

                       8           Hydrogen            5

                       3           Oxygen                3

This reaction is unbalanced

                   (NH₄)₂CO₃  ⇒   2NH₃  +  CO₂  + H₂O

               Reactants    Elements     Products

                      2            Nitrogen             2
