Answer:

Because it contains only two elements.

Explanation:

A binary compound is a compound made up of only two elements. Barium chloride contains:

1. Barium.

2. Chlorine.

Since Barium chloride contains only two elements, it is therefore a binary compound.

9. Calculate the molar mass of each substance. Identify each substance as ammonia

alexdok [17]

Explanation:

Molecular mass:

Atomic masses:

N = 14g/mol H = 1g/mol S = 32g/mol O = 16g/mol Cl = 35.5g/mol

C = 12g/mol

NH₃ = 14 + 3(1) = 17g/mol

SO₂ = 32 + 2(16) = 64g/mol

Cl₂ = 2(35.5) = 71g/mol

N₂ = 14(2) = 28g/mol

CH₄ = 12 + (4 x 1) = 16g/mol

To solve this problem;

we need to derive an equation to find the molecular mass from the given densities on the table.

At STP;

Number of moles = $\frac{volume of gas}{y22.4}$ eqn (i)

Also;

Number of moles = $\frac{mass}{molar mass}$ eqn (ii)

Now we can equate the two equations;

$\frac{volume of gas}{y22.4}$ = $\frac{mass}{molar mass}$

since density is known, we have to rewrite the relationship by making molar mass the subject of the expression:

Molar mass = $\frac{mass x 22.4}{volume of gas}$

we know that;

Density = $\frac{mass }{volume }$

Molar mass = density x 22.4

Now ;

Molar mass for 1.25g/L = 1.25 x 22.4 = 28g/mol; which is for N₂

Molar mass for 2.86g/L = 2.86 x 22.4 = 64.1g/mol; which is for SO₂

Molar mass for 0.714g/L = 0.714 x 22.4 = 16g/mol; which is for CH₄

Consider the reaction of NO and CO to form N2 and CO2, according to the balanced equation: 2 NO (g) + 2 CO (g) → N2 (g) + 2 CO2

Gekata [30.6K]

The image is not given in the question, it is attached below:

<u>Answer:</u> The excess reactant is NO, the limiting reactant is CO and the products are shown in the image attached below.

<u>Explanation:</u>

In the given image:

Red spheres represent oxygen atoms, blue spheres represent nitrogen atoms and black spheres represent carbon atoms

The combination of 1 black and 2 red spheres will represent carbon dioxide $(CO_2)$ compound

The combination of 2 blue spheres will represent nitrogen molecule $(N_2)$

The combination of 1 blue and 1 red sphere will represent nitrogen monoxide $(NO)$ compound

The combination of 1 black and 1 red sphere will represent nitrogen monoxide $(NO)$ compound

Limiting reagent is defined as the reagent which is completely consumed in the reaction and limits the formation of the product.

Excess reagent is defined as the reagent which is left behind after the completion of the reaction.

We are given:

Given moles of NO = 6 moles

Given moles of CO = 4 moles

For the given chemical equation:

$2NO(g)+2CO(g)\rightarrow N_2(g)+2CO_2(g)$

By stoichiometry of the reaction:

If 2 moles of CO reacts with 2 moles of NO

So, 4 moles of CO will react with = $\frac{2}{2}\times 4=4mol$ of NO

As the given amount of NO is more than the required amount. Thus, it is present in excess and is considered as an excess reagent.

Thus, CO is considered a limiting reagent because it limits the formation of the product.

Hence, the excess reactant is NO, the limiting reactant is CO and the products are shown in the image attached below.
