Answer:

Explanation:
When adding or subtracting values, you must round your answer to the same "place" as the measurement with its last significant figure furthest to the left.
That is, you round off to the same number of decimal places as the measurement with the fewest decimal places.

The measurements of 14.0 and 10.6 have one digit after the decimal point, so you round the sum to have only one digit to the right of the decimal.
The number to be dropped (3) is less than 5, so you drop it.

It is when two or more different substances which are mixed
If the enthalpy change is negative, then the reaction is exothermic because heat energy was lost to the surroundings.
If the enthalpy change was positive, then the reaction was endothermic because heat energy was gained from the surroundings!
