Answer:
As the specific heat capacity for pure diamond is 0.5091
and it is different from the specific heat capacity found that is 0.2699, the diamond sample is not pure.
Explanation:
1. As the problem says the equation that describes the amount of heat gained or lost by a substance is:
q=Cp*m*ΔT
where q is the amount of heat, Cp is the specific heat capacity, m is the mass and ΔT is the change in the temperature.
2. Solving for specific heat capacity:
3. Replacing values:
As the specific heat capacity for pure diamond is 0.5091 and it is different from the specific heat capacity found that is 0.2699, the diamond sample is not pure.
Answer:
26 grams of D will be produced.
Explanation:
The reaction is given by:
A + B -----> C + D
Mass of A reacted = 21 g
Mass of B reacted = 22 g
Mass of C formed = 17 g
Mass of D formed = m =?
According to law of conservation of mass, the total mass of the reactants used is equal to the total mass of the product formed.
Then:
mass of A reacted + mass of B reacted = mass of C formed + mass of D formed
21 + 22 = 17 + m
m = 26 g
