Answer:

CH₄ will diffuse at faster rate.

Explanation:

According to Graham's law,

The rate of diffusion is inversely proportional to the square root of molar mas of gas.

It is given in question the molar mass of CH₄ is 16 g. Thus the square rot of 16 is.

√16 = 4

The molar mass of SO₂ is 64 g and the square root is,

√64 = 16

As it is stated that diffusion rate is inversely related to the square root of molar mass thus the diffusion rate of SO₂ is lower while methane diffuse faster.

<u>Answer: </u>

The value of $\left(2.5 \times 10^{10}\right) \times\left(3.5 \times 10^{-7}\right)$ is 8750

<u>Solution: </u>

$\left(2.5 \times 10^{10}\right) \times\left(3.5 \times 10^{-7}\right)$

$\Rightarrow\left(2.5 \times 10^{10} \times 3.5 \times 10^{-7}\right)$

$\Rightarrow\left(2.5 \times 3.5 \times\left(10^{10} \times 10^{-7}\right)\right)$

$\Rightarrow(2.5 \times 3.5) \times\left(10^{10+(-7)}\right)$

$\Rightarrow(2.5 \times 3.5) \times 10^{3}$

$\Rightarrow 8.75 \times 10^{3}$

$\Rightarrow 8.75 \times 1000=8750$

How many moles of sulfur trioxide are formed from 3 moles of oxygen using the given

fiasKO [112]

Answer:

6 moles of SO₃ formed.

Explanation:

Given data:

Number of moles of SO₃ formed = ?

Number of moles of oxygen react = 3 mol

Solution:

Chemical equation;

2SO₂+ O₂ → 2SO₃

now we will compare the moles of oxygen and sulfur trioxide.

O₂ : SO₃

1 : 2

3 : 2/1×3 = 6 moles

Thus, six moles of SO₃ will formed.
