Particles are farther apart in gases so substance X is water vapor
Explanation:
The best statement that fits the two described substances is that particles are farther apart in gases so substance X is water vapor. For a give mass of substance, gases occupies more volume.
Gases do not have specific volumes, occupy space randomly and fills whichever container they are found in.
Liquids on the other hand like solids have specific volume because their particles are very close together.
Particles of gases are random and their molecules are far apart.

Answer:
Hydrogen: -141 kJ/g
Methane: -55kJ/g
The energy released per gram of hydrogen in its combustion is higher than the energy released per gram of methane in its combustion.
Explanation:
According to the law of conservation of the energy, the sum of the heat released by the combustion and the heat absorbed by the bomb calorimeter is zero.
Qc + Qb = 0
Qc = -Qb [1]
We can calculate the heat absorbed by the bomb calorimeter using the following expression.
Q = C . ΔT
where,
C is the heat capacity
ΔT is the change in the temperature
<h3>Hydrogen</h3>
Qc = -Qb = -C . ΔT = -(11.3 kJ/°C) . (14.3°C) = -162 kJ
The heat released per gram of hydrogen is:
<h3>Methane</h3>
Qc = -Qb = -C . ΔT = -(11.3 kJ/°C) . (7.3°C) = -82 kJ
The heat released per gram of methane is:

Carbon
Explanation:
Micronutrients include elements or groups needed by the body in order to survive. These elements or groups include vitamins and minerals. Micronutrients can be divided into four categories:
1. water-soluble vitamins
2. Fat-soluble vitamins
3. Macrominerals
4. Trace minerals
