Answer:

Total body water (TBW) will be unchanged because the woman replaced all volume lost in sweat by drinking water. Hematocrit will be increased because of the shift of water from ECF to ICF and the shift of water into the red blood cells (RBCs), which causes their volume to increase.

Bingel [31]

At its discovery, benzene was recognized to be a unique unsaturated hydrocarbon because it either failed to react, by substitution with common reagents or reacted by addition that led to reactions with alkenes.

<h3>What are unsaturated hydrocarbons?</h3>

Unsaturated hydrocarbons are the hydrocarbons which have at least on double or triple carbon to carbon bond in its molecules.

All other hydrocarbons are unsaturated except for the alkanes and the cyclic alkanes.

Benzene is an aromatic compound which has a special six-carbon ring with are resonance structure reflecting the presence of three carbon-carbon bonds in its molecules.

The common reactions of unsaturated hydrocarbons are substitution and addition reactions.

However, benzene on its discovery did not undergo any of these reactions.

In conclusion, benzene showed a difference when compared with the common unsaturated hydrocarbons as it did not undergo either substitution or addition reactions.

The production of ammonia (NH3) is exothermic and is in equilibrium with its breakdown (which is endothermic):
olya-2409 [2.1K]

Answer:

The equilibrium will shift to produce less ammonia

Explanation:

According to Le Chatelier's principle, the reaction will try to oppose anything that is done on it, if it was at equilibrium.

When the concentration of H2 is decreased, you are decreasing the concentration of hydrogen so the reaction tries to increase the concentration of hydrogen by breaking down the ammonia on the products side. This will decrease the output of ammonia
