For all the reactions listed, the moles of products and limiting reactants are;

1. Molar cofficient - 6, oxygen is the limiting reactant

2. Molar coefficient - 8 chlorine is the limiting reactant

3. Molar coefficient - 4 and CO2 is the limiting reactant

<h3>What is a chemical reaction?</h3>

A chemical reaction is a combination of reactants that yields products. Recall that the limiting reactant is the reactant that nis present in the least amount.

Let us now complete each reaction;

1. The molar coefficient of the product in reaction 1 is 6 and oxygen is the limiting reactant

2. The molar For all the reactions listed coefficent of the product in reaction 2 is 8 and chlorine is the limiting reactant

3. The molar coefficient of the product in reaction 3 is 4 and the limiting reactant is CO2.

Explain why a steel object continues to rust even after its outer layers have corroded.
Aliun [14]

Answer:

Explanation:

During that process of being exposed to air and water while being left outside or in the elements for an extended period of time, a variety of different types of rusts can form, but the most common form is Fe2O3. Rust only forms on the outside of a metal surface because it requires exposure of oxygen and water to rust.

Fe(s) + 2HCl(aq) --&gt; FeCl2(aq) + H2(g)
soldier1979 [14.2K]

Answer:

In the option(A) moles of HCl left are 0.100 moles which is wrong, making the option incorrect.

Explanation:

Fe(s) + 2HCl(aq)\rightarrow  FeCl_2(aq) + H_2(g)&#10;

Moles of HCl = n

Molarity of HCl = 1.0M

Volume of HCl solution = 30.0 mL = 0.030 L (1 mL = 0.001L)

Moles=Molarity\times Volume (L)

n=1.0M\times 0.030 L=0.030 mol

Moles of Fe = \frac{0.56 g}{56 g/mol}=0.01 mol

According to recation , 1mol of Fe reacts with 2 mol HCl. Then 0.01 mole of Fe will recat with :

\frac{2}{1}\times 0.01 mol= 0.02 mol of HCl

This means that HCl uis in excess , hence excessive reagent.

Moles of HCl left unreacted :

= 0.030 mol - 0.020 mol = 0.010 mol

But in the option moles of HCl left are 0.100 moles which is wrong, making the option incorrect.
