Air that has a 100 percent relative to humidity is ... Saturated .
saturated means holding as much water or moisture or as how it can be absorbed.
<span>The Keq expression for I2(s) + H2O(l) H + (aq) + I-(aq) + HOI(aq) equilibrium is
H2(g) + I2(g) <----> 2 HI(g).In this Keq expression hydrogen reacts with iodine gives Hydrogen Iodide.HI is a diatomic molecule and it is one of the primary source of iodine which act as a reducing agent.Totally it is the reverse chemical equilibrium reaction.</span>
The reaction shown here is an exothermic reaction.
<h3>What is an exothermic reaction?</h3>
An exothermic reaction is one in which the energy of the reactants is greater than the energy of the products. This implies that energy is given out in the process. Whether a reaction is endothermic or exothermic shows in the nature of the reaction profile curve.
For an endothermic reaction, the part of the diagram that represents the energy of the products is higher than the part that represents the energy of the reactants. This is clear from the image attached here.
If we look at the reaction graph very well, we will observe that the energy of the reactants is far above that of the products. Thus it follows that the reaction shown here is an exothermic reaction.

Answer:
1. Density can be used to identify a substance
2. Density can be used to ascertain whether a substance will float in water.
Explanation:
The calculation of the density of a substance can be used to identify the substance. If the density of a substance is calculated accurately, and compared with a table of standard densities, then we can identify that substance.
Also, density determines whether an object will float or sink in water. If an object is less dense than water then it will float in water. If it is denser than water, then it will sink in water.
