Consider the balanced equation below. 8H2 + S8 Right arrow. 8H2S Based on the mole ratios, what can most likely be predicted? 1
Arte-miy333 [17]

Answer:

8 mol of hydrogen will react with 1 mol of sulfur.

Explanation:

We'll begin by writing the balanced equation for the reaction.

This is given below:

8H2 + S8 —> 8H2S

Now, let us carefully observe the mole ratio of the reactants.

This is illustrated:

The mole ratio of the reactants ( i.e H2 and S8) is 8 : 1

From the balanced equation above,

We can thus, concluded that:

8 moles of H2 will reacted with 1 mole of S8.

Catalytic converters made of palladium (pd) reduce automobile pollution by catalyzing the reaction between unburned hydrocarbons
Doss [256]
Unburned hydrocarbon on reacting with oxygen undergoes combustion reaction. However, the activation energy of this reaction is significantly high. When a catalyst like Pd is added to the reaction system, it provides active sites for the reaction to occur. It acts are a heterogeneous catalyst. It is pertinent of note that catalyst is refereed as heterogeneous, when it exist in different phase as compared to reactant and products. In present case, reactants and products are in gas phase, while catalyst is in solid phase. Due to availability of larger surface area at active site of Pd, activation energy of reaction decreases and decrease in activation energy favors higher reaction rates.

After centrifugation of the sample, the student was not careful and some of the solid was transferred to the Erlenmeyer flask al
Tju [1.3M]

The fact that some of the solid was transferred would decrease the mass of the limiting reactant.

<h3>What is the limiting reactant?</h3>

We know that in a chemical reaction, there are at least two substances that are combined in order to give the product of the reaction. We also know that the product that we obtain must be in accordance to the stoichiometry of the reaction.

It is common to see that one of the reactants would be present in a very large amount while the other reactant would be present only in quite a small amount. The reactant that is present in a small amount is said to be the limiting reactant while the one that is present in the large amount is said to be the reactant that is in excess.

Having said this, we know that the mass of the limiting reactant can be obtained from the mass of the solid that is obtained after the reaction.

If we do not take out all of the solid from the centrifuge, the mass would not be accurately weighed and the mass of the limiting reactant would not be accurately determined.
