One mole of sodium sulfate is 143.04, so just multiply that times 6.31.
I may be wrong call me out if I am
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
To find the heat released.
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

(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
1 Carbon 1
8 Hydrogen 8
3 Oxygen 3
Now, the reaction is balanced,
The coefficient for Carbon dioxide is 1
