Answer:
Carbon dioxide is produced, and as a gas, it was not captured to measure its mass.
Explanation:
To calculate for the final temperature, we need to remember that the heat rejected should be equal to the absorbed by the other system. We calculate as follows:
Q1 = Q2
(mCΔT)1 = (mCΔT)2
We can cancel m assuming the two systems are equal in mass. Also, we cancel C since they are the same system. This leaves us,
(ΔT)1 = (ΔT)2
(T - 80) = (0 - T)
T = 40°C
Answer:
1
Explanation:
The numbers in front of the formulas (the coefficients) tell you how many moles of a substance are involved in a reaction.
If no coefficient is shown, we assume it is 1.
NOCl has no coefficient, so 1 mol of NOCl is in the balanced equation.
B. False
When the maximum amount of solute has been dissolved in a given amount of solvent, we say that the solution is saturated with solute.
