The chemical equations are the representation of the chemical formula involved in the equation as the reactant and the formed product.

<h3>What will be the form of oxygen?</h3>

The given chemical equations are:

$\rm C\;(s)\;+\;\frac{1}{2}\;O_2\;(g)\rightarrow\;CO\;(g)$
$\rm CO\;(g)+\;\frac{1}{2}\;O_2\;(g)\rightarrow\;CO_2\;(g)$

The final chemical equation formed for the formation of Carbon dioxide is the sum of the two equations.

The final equation is achieved by substituting equation 1 in equation 2.

$\rm C\;(s)\;+\;\frac{1}{2}\;O_2\;(g)\;+\;\dfrac{1}{2}\;O_2\;(g)\;\rightarrow\;CO_2\;(g)\\\\ C\;(s)\;+\;O_2\;(g)\;\rightarrow\;CO_2\;(g)$

The oxygen in the final equation appears as reactant Upper O subscript 2 (g). Thus, option A is correct.

When water that contains a solute freezes, the solute is not typically incorporated into the crystal lattice (i.e. it is exclude

Ilya [14]

Answer:

It matters

Explanation:

Pure substance are known to have a sharp freezing point. However, the presence of solute lowers the freezing point of the solvent. The best time to measure the freezing point is when the freezing process is just beginning.

It will be an error to measure the freezing point when the part of the solution has already frozen.
