Chemistry
1 answer:
Nata [24]2 years ago
5 0

Answer:

Mass, m = 141.96 kg

Explanation:

Given that,

Moles = 5.07

Molar mass of N₂ = 28 g/mol

We need to find the mass of 5.07 mol N₂.

We know that,

No of moles is equal to mass divided by molar mass i.e.

n=\dfrac{m}{M}

Where

m is mass of 5.07 mol of N₂

So,

m=n\times M\\\\m=5.07\times 28\\\\m=141.96\ kg

So, the required mass of 5.07 mol N₂ is 141.96 kg.

4.Identify each substance in the following word equation as a reactant or a product
Anastaziya [24]

Explanation:

4.                 limestone heat lime + carbon dioxide

The reactants in this expression above is limestone

The products of the reaction is carbon dioxide and lime

Reactant is the species that gives the product and it is usually found on the left hand side of the expression.

The product is the substance on the right hand side of the expression that forms through the experiment.

Heat is used to facilitate the reaction.

5. An exothermic reaction is a reaction in which heat is given off.

An endothermic reaction is a reaction in which heat is absorbed in the process.

An exothermic reaction is always warmer after the reaction whereas an endothermic reaction is colder at the end of the reaction.

Q #13 How many moles of MgCl2 are there in 350. g of compound?
Vaselesa [24]

<u>Answer:</u>

3.67 moles

<u>Step-by-step explanation:</u>

We need to find out the number of MgCl_2 moles present in 350 grams of a compound.

Molar mass of Mg = 24.305

Molar mass of Cl_2 = 35.453

So, one mole of MgCl_2 = 24.305 + (35.453 * 2) = 95.211g

1 Mole in 1 molecule of MgCl_2 = \frac{1}{95.211} = 0.0105

Therefore, number of moles in 350 grams of compound = 0.0105 * 350

= 3.67 moles
