Chemistry
1 answer:
Papessa [141]3 years ago
3 0

Answer:

0.93 mol

Explanation:

Given data:

Number of moles of Na atom = ?

Number of atoms = 5.60× 10²³

Solution:

Avogadro number:

The given problem will solve by using Avogadro number.

It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance. The number 6.022 × 10²³ is called Avogadro number.

1 mole = 6.022 × 10²³ atoms

5.60× 10²³ atoms ×  1 mol / 6.022 × 10²³ atoms

0.93 mol

Hydrocarbons, compounds containing only carbon and hydrogen, are important in fuels.The heat of combustion of cyclopentane, C5H1
shtirl [24]

Answer : The balanced equation for the complete combustion of cyclopentane will be :

2C_5H_{10}+15O_2\rightarrow 10CO_2+10H_2O

Explanation :

As we know that the hydrocarbons can undergo complete or incomplete combustion that depends on the amount of oxygen available.

Complete combustion : It takes place when there is a good supply of oxygen. In this, hydrocarbon react with the oxygen to give carbon dioxide and water as a product.

The general reaction will be :

\text{Hydrocarbon}+O_2\rightarrow CO_2+H_2O

Incomplete combustion : It takes place when there is a poor supply of oxygen. In this, hydrocarbon react with the oxygen to give carbon monoxide, carbon dioxide and water as a product.

The general reaction will be :

\text{Hydrocarbon}+O_2\text{(limited)}\rightarrow CO+CO_2+H_2O

As per question, the complete combustion of cyclopentane react with oxygen to gives carbon dioxide and water as a product.

Therefore, the balanced chemical reaction will be :

2C_5H_{10}+15O_2\rightarrow 10CO_2+10H_2O

Which of the following numbers will produce the same number when rounded to two significant figures? (2.3)
prohojiy [21]
2.10

The 0 after 1 is not significant and does not affect the value of the number; therefore, when the number will be rounded to two significant figures, it will become 2.1, so it will be the same.
