<span>Density is a value for
mass, such as kg, divided by a value for volume, such as m3. Density is a
physical property of a substance that represents the mass of that substance per
unit volume.
Density = 1.80 g / 2 L = 0.9 g/L</span>

Answer:
C.) 2,1,2
Explanation:
You have to balance the equation by getting the number of elements on the left and right side to equal. Before balancing there is one more oxygen on the left side than the right side. You have to change the coefficient in front of H2O to fix this, and that means adding a "2" in front of the H2 to get that to equal as well.
You end up with 2H₂+10₂→ 2H₂O
Concentration, temperature and catalyst is directly related to Forensic Science and toxicology due to their effects.
<h2>Relation of quantity, temperature</h2>
The concentration, temperature and catalyst is related to Forensic Science and toxicology because different substances show their effects at different dosage which is responsible for the change in the subject who is allowed to them.
At a normal range, a substance or liquid has no negative effect when it is used at high concentration it can cause adverse effect on the body. Some chemicals are in good condition when it is placed in normal temperature range but shows adverse effect when the temperature becomes high so we can conclude that concentration, temperature and catalyst is directly related to Forensic Science and toxicology.

The moles of hydrogen produced in the reaction has been 0.105 mol. Hence, option D is correct.
The balanced chemical equation for the decomposition of Ammonia has been:
<h3>Computation for moles of Hydrogen produced</h3>
From the balanced chemical equation, decomposition of 2 moles of ammonia produces, 3 moles of hydrogen and 1 mole, nitrogen.
The moles of hydrogen produced along with 0.0351 mol nitrogen has been:
Thus, the moles of hydrogen produced in the reaction has been 0.105 mol. Hence, option D is correct.
