Consider the following intermediate chemical equations. 2 equations. First: upper C (s) plus one half upper O subscript 2 (g) ri
Dmitrij [34]

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

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:

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

The small bags of silica gel you often see in a new shoe box are placed there to control humidity. Despite its name, silica gel
Lilit [14]

Answer:

The sign of \Delta GΔG is negative.

The sign of \Delta HΔH is negative.

The sign of \Delta SΔS is negative.

Explanation:

The water vapor is adsorbed on silica gel due to strong hydrophilicity of silica get towards the water.

The thermodynamic properties of adsorbate and adsorbent changes after adsorption. Silica gel is very porous and hydrophilic, thus, it absorbs the water from the shoe box.

The adsorption process occurs spontaneously, therefore Delta G < 0.

When adsorption occurs, bonds are formed between water molecules and SiO2, and the bond formation process is exothermic (heat is released).

Thus, Delta H < 0.

The water molecules become immobilized on the surface when adsorption occurs, thus, entropy/disorder decreases.

So, Delta S < 0.
