Answer:</h3>
59.878 Kilo joules

Explanation:</h3>
We are given;
- Molar heat of vaporization for water as 10.79 kJ/mol
- Mass of water 100 grams
We are required to calculate the amount of energy absorbed to convert water to ice.
- We need to know that the process of conversion of water to steam without change in temperature is known as vaporization or boiling.
- Therefore, heat absorbed is calculated by multiplying the mass of water or the number of moles by heat of vaporization.
- That is, Q = m × ΔHf
- When given the number of moles and the molar heat of vaporization, then Q = n × ΔHf
In this case;
Mass of water = 100 g
But, molar mass of water = 18.02 g/mol
Moles of water = 100 g ÷ 18.02 g/mol
= 5.549 Moles
Therefore;
Q = 5.549 moles × 10.79 kJ/mol
= 59.878 Kilo joules
The arrangement of particles that make up an ionic compound would be an ionic lattice type of crystal arrangement. An ionic lattice type of structure will be formed due to many of the ionic bonds formed between the oppositely charged ions of the metal and nonmetal.

Answer:
"After 1 half-life there will be 50% of the original isotope, and 50% of the decay product.
After 2 half-lives there will be 25% of the original isotope, and 75% of the decay product.
After 3 half-lives there will be 12.5% of the original isotope, and 87.5% of the decay product.
After 4 half-lives there will be 6.25% of the original isotope, and 93.75% of the decay product." -Stephen Frantz, Former Director of the Reed College Nuclear Reactor
