Answer:
1.2 × 10⁴ cal
Explanation:
Given data
- Initial temperature: 80 °C
We can calculate the heat released by the water (
) when it cools using the following expression.

where
c is the specific heat capacity of water (1 cal/g.°C)

According to the law of conservation of energy, the sum of the heat released by the water (
) and the heat absorbed by the reaction (
) is zero.

Answer:
D: lose an electron
Explanation:
when an atom loses an electron it's positively charged and when it gain an electron it is negatively charged
The correct answer would be 3.49 times 10^ minus 24 molecules
