A mixture of He, Ne, and N2 gases has a pressure of 1.943 atm. If the pressures of He and Ne are 0.137 atm and 0.566 atm, respec

Ad libitum [116K]

Answer:

The parcial pressure of N₂ in the mixture is 1.24 atm.

Explanation:

The pressure exerted by a particular gas in a mixture is known as its partial pressure. So, Dalton's law states that the total pressure of a gas mixture is equal to the sum of the pressures that each gas would exert if it were alone:

PT = PA + PB

This relationship is due to the assumption that there are no attractive forces between the gases.

In this case:

PT=PHe + PNe + PN₂

You know:

PT= 1.943 atm
PHe= 0.137 atm
PNe= 0.566 atm
PN₂= ?

Replacing:

1.943 atm= 0.137 atm + 0.566 atm + PN₂

Solving:

1.943 atm= 0.703 atm + PN₂

1.943 atm - 0.703 atm= PN₂

1.24 atm= PN₂

<u><em>The parcial pressure of N₂ in the mixture is 1.24 atm.</em></u>

Consider the reaction for the combustion of benzene: 2 C6H6(g) 15 O2(g) ---> 12 CO2(g) 6 H2O(l) What mass of H2O is produced

irakobra [83]

Answer: Mass of water produced is 17.3 grams

Explanation:

To calculate the number of moles, we use the equation:

$\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}$ .....(1)

For benzene:

Given mass of benzene = 25.0 g

Molar mass of benzene= 78 g/mol

Putting values in equation 1, we get:

$\text{Moles of benzene}=\frac{25.0g}{78g/mol}=0.32mol$

The chemical equation for the reaction follows:

$2C_6H_6(g)+15O_2(g)\rightarrow 12CO_2(g)+6H_2O(l)$

As, oxygen is an excess reagent. Thus benzene is considered as a limiting reagent because it limits the formation of product.

By Stoichiometry of the reaction:

2 moles of benzene produces 6 moles of water

So, 0.32 moles of benzene will produce = $\frac{6}{2}\times 0.32=0.96moles$ of water

Now, calculating the mass of water from equation 1, we get:

Molar mass of water= 18 g/mol

Moles of water = 0.96moles

Putting values in equation 1, we get:

$0.96mol=\frac{\text{Mass of water}}{18g/mol}\\\\\text{Mass of water}=17.3g$

Thus mass of water produced is 17.3 grams

0.00632 into a scientific notation

ddd [48]

Answer:

6.32 × 10⁻³

3.2560008× 10⁷

5.630× 10⁰

9.5002× 10¹

Explanation:

Scientific notation is the way to express the large value in short form.

The number in scientific notation have two parts.

The digits (decimal point will place after first digit)

× 10 ( the power which put the decimal point where it should be)

For example:

0.00632

In scientific notation = 6.32 × 10⁻³

32,560,008

In scientific notation = 3.2560008× 10⁷

5.630

In scientific notation = 5.630× 10⁰

95.002

In scientific notation = 9.5002× 10¹
