Answer:
B. 4 ham slices
Explanation:
A chemical reaction involves one or more substances known as reactants combining chemically to give one or more substances known as products.
Reactants in chemical reactions combine in definite mole or mass ratios to give products. Therefore, when one substance is present in excess of what is required to combine with another to form products, that substance is known as the excess reagent. The other substance which is present in a smaller amount and which when used up, the reaction stops is known as the limiting reagent.
From the illustration of the sandwiches in the question, the recipe for one sandwich represents the chemical equation of a reaction. The equation form is given below:
2 cheese slices + 1 ham slice + 2 bread slices ---> 1 sandwich
The ratio of the reactant is 2 : 1 : 2
From the available ingredients, 12 cheese slices, 10 ham slices, 12 bread slices.
12 cheese slices will require 6 ham slices and 12 bread slices to produce 6 sandwiches.
However, since there are 10 ham slices, 4 ham slices will be left over unused. This is the excess or leftover reactant.
Hurricanes derive their energy from the Latent heat of condensation.
Hence, Option (1) is correct answer.
<h3>What is Latent Heat ? </h3>
The heat that is released or absorbed during a phase change of a substance is known as Latent heat.
<h3>What is Hurricanes ?</h3>
Hurricanes is basically a type of storm called a tropical cyclone. These are intense low pressure areas. Hurricanes derive their energy from the latent heat of CONDENSATION.
Thus from the above conclusion we can say that Hurricanes derive their energy from the Latent heat of condensation.
Hence, Option (1) is correct answer.

<span>Compared to a weak acid, a strong acid has a greater habit of losing it's proton (hydrogen). For example, when hydrochloric acid (strong) encounters water, it is much more likely to donate its hydrogen to water, compared to nitrous acid (weak).</span>
The answer is (4). If you look at a Maxwell-Boltzmann energy curve, you will see that lowering the activation energy will increase the proportion of molecules with sufficient energy for a successful reaction collision. Therefore, a reaction with lower activation energy will proceed more quickly. Often, this lower activation energy is obtained by another mechanistic pathway. Catalysts increase reaction speed through these two basic mechanisms.
I believe the answer is B
