Answer 1

При сжигании 3.6 г углерода в сосуде , содержащем 4.48 г кислорода.
Нет!

Answer 2

Answer:

No, 64 g of oxygen is not enough to burn 48 g of carbon.

The balanced chemical equation for the combustion of carbon can be used to determine the stoichiometry of the reaction. The balanced equation is:

C + O2 → CO2

From the equation, it is clear that 1 mole of carbon reacts with 1 mole of oxygen to produce 1 mole of carbon dioxide. The molar mass of carbon is 12 g/mol, and the molar mass of oxygen is 16 g/mol.

To calculate the amount of oxygen needed to burn 48 g of carbon, we can use the following steps:

1. Calculate the moles of carbon: - 48 g of carbon / 12 g/mol = 4 moles of carbon

2. Calculate the moles of oxygen needed: - 4 moles of carbon * 1 mole of O2 / 1 mole of C = 4 moles of O2

This means that 4 moles of oxygen are needed to burn 48 g of carbon. Since the molar mass of oxygen is 16 g/mol, the mass of 4 moles of oxygen is:

4 moles of O2 * 16 g/mol = 64 g of O2

Therefore, 64 g of oxygen is required to burn 48 g of carbon according to the stoichiometry of the balanced chemical equation.

However, if we consider the actual reaction, it is important to note that the reaction may not be complete due to various factors such as incomplete combustion, impurities, or other reactions taking place. Therefore, in practical scenarios, the actual amount of oxygen required may vary.
