The equation below shows the reaction of hydrochloric acid (hcl) with sodium hydroxide (naoh). hcl (aq) + naoh (aq) → h2o (l) + nacl (aq) + heat what will happen if the temperature is decreased? a. the reaction will slow down. b. the reaction will proceed in reverse. c. the water (h2o) will begin rapidly evaporating. d. the sodium (na) and hydrogen (h) will combine to form sodium hydride (nah).

Option (C) is the correct answer.

Explanation:

Le Chatelier's principle states that when a system is in equilibrium then any change in the reaction will shift the equilibrium in a direction which is opposing the change.

So, in the given exothermic reaction when we decrease the temperature then there will be increase in production of water and NaCl.

As a result, water will evaporate at a faster rate.

Hence, we can conclude that for the given equation if the temperature is decreased then the water (H2O) will begin rapidly evaporating.

when atmosphere interacts with biosphere they focuses on on the sources and sinks of green house gases (ghgs) air pollutants, particular matters, water and energy between the earth's surface and the atmosphere. the biosphere affects the climate. the atmosphere and biosphere are in constant interaction with each other, and all living things rely on gases in the atmosphere for life. organisms such as animals take in oxygen gas form the atmosphere to use in every cell of their body for smooth functioning of daily routine exercises.

so what is the problem with your lab report and whats the subject of the lab report? i will you
