4 0

Answer:

A, B and D

Explanation:

The rate determining step decides the overall rate of reaction and the species involved in the rate determining step determine the overall order of reaction. All the elementary steps in the mechanism sum up to give the overall reaction equation. However, transient intermediates only appear in elementary reaction equations and not the overall reaction equation.

Why are all atoms electrically neutral?
Anna11 [10]

Answer: Atoms are neutral if they have the same number of charged protons and electrons, balancing positive and negative charges. ... This is because water itself has slight charges. Answer 7: Atoms are electrically neutral because they have equal numbers of protons (positively charged) and electrons (negatively charged).

H20 (s) -&gt; h20 (g)<br> endothermic or exothermic
noname [10]

Answer:

Endothermic.

Explanation:

Hello there!

In this case, it is necessary to keep in mind that exothermic processes are characterized by the release of energy and the endothermic processes by the absorption of heat. In such a way, every process from solid to liquid or gas is endothermic as they require energy to separate the molecules and therefore turn out in the phase change. On the other hand, every process from gas to liquid or solid is exothermic as heat is released to rejoin the molecules and produce the phase change.

Therefore, since solid water molecules tend to be well-arranged, it is necessary to add heat to the system to produce the phase change until gas; in such a way, this process is endothermic as energy must be absorbed by the ice.

Best regards!
