how many moles of carbon monoxide can be produced from 8 moles of carbon if carbon is the limiting reagent?

Chemistry
1 answer:
Mademuasel [1]3 years ago
6 0

Answer:

8 moles of CO

Explanation:

To produce carbon monoxide we begin from C and O₂ as this reaction shows:

2C + O₂ → 2CO

Therefore, 2 moles of C can produce 2 moles of CO

If I have 8 moles of C, I must produce 8 moles of CO

Ratio is 1:1

When h2o is added to a compound in a chemical equation, a new compound can be formed via what type of reaction?
Scorpion4ik [409]

When water is added to a compound in a chemical equation, a new compound can be formed, it is called a hydrolysis reaction.

<h3>What is hydrolysis reaction?</h3>

There are so many kinds of reaction in chemistry we know that a chemical reaction occurs between reactant molecules in order to yield products in the reactants.

The hydrolysis reaction is a breaking up reaction. In a hydrolysis reaction, water is used to break up a molecule. Hence in a hydrolysis reaction water could be regarded as one of the reactants in the reactions going on in the system.

We know that a hydrolysis is a reaction in which water reacts with another reactant molecule to yield products in the reaction. Thus, when water is added to a compound in a chemical equation, a new compound can be formed, it is called a hydrolysis reaction.

A mixture of 5L of H2 and 3L O2 reacts to form H2O (g) at constant T and P .Find the
slamgirl [31]

The  volume of H₂O = 5 L

<h3>Further explanation</h3>

Given

5L of H₂ and 3L O₂

Reaction

2H₂ (g) + O₂(g)  ⇒2H₂O(g)

Required

The  volume of H₂O

Solution

Avogadro's hypothesis:  

<em>In the same T,P and V, the gas contains the same number of molecules  </em>

So the ratio of gas volume will be equal to the ratio of gas moles  

mol H₂ = 5, mol O₂ = 3

  • Find limiting reactants

From equation, mol ratio H₂ : O₂ = 2 : 1, so :

\tt H_2\div O_2=\dfrac{mol~H_2}{coefficient}\div \dfrac{mol~O_2}{coefficient}\\\\=\dfrac{5}{2}\div \dfrac{3}{1}=2.5\div 3\rightarrow H_2~limiting~reactant(smaller~ratio)

  • Find volume H₂O

mol H₂O based on mol H₂, and from equation mol ratio H₂ : H₂O=2 : 2, so mol H₂O = 5 mol and the volume also 5 L

The cost of painting the circular traffic sign shown below is $3.50 per square foot. How much, to the nearest dollar, will it co
KiRa [710]

The cost of painting the traffic sign of 7.065 square feet is approximately equal to 25 dollar.

<u>Explanation:</u>

The cost of painting the circular traffic sign is given as 3.50 dollar per square feet. The diameter of the traffic sign is 36 inch, then its radius will be \frac{36}{2} = 18 inches.

But as the cost is given in unit of feet, we have to convert the radius from inches to feet.

1 inches = 0.0833 feet

18 inches = 18 × 0.0833 feet

So, the radius of the traffic sign will be approximately equal to 1.5 feet.

The area of the traffic sign will be \pi r^{2} = 3.14 \times 1.5 \times 1.5 = 7.065 square feet.

So, if the cost of painting 1 square feet of traffic sign is 3.50 dollar, then

cost of painting 7.065 square feet of traffic sign =  3.50 × 7.065 = 24.7 dollar.

Thus, the cost of painting the traffic sign of 7.065 square feet is approximately equal to 25 dollar.
