Answer:

3.41 x10⁶ torr

Explanation:

To solve this problem we need to remember the equivalency:

1 torr = 133.322 Pa

Then we can proceed to<u> convert 4.55×10⁸ Pa into torr.</u> To do that we just need to multiply that value by a fraction number, putting the unit that we want to convert <em>from</em> in the <em>denominator</em>, and the value we want to convert <em>to</em> in the <em>numerator</em>:

4.55x10⁸ Pa * \frac{1torr}{133.322Pa} = 3.41 x10⁶ torr

Methane CH4 (g) reacts with oxygen gas to produce carbon dioxide and water. ____________________________________________________
nordsb [41]

<u>Answer:</u> The chemical equations are written below.

<u>Explanation:</u>

<u>For a:</u> Methane reacts with oxygen gas to produce carbon dioxide and water.

Combustion reaction is defined as the reaction in which a hydrocarbon reacts with oxygen gas to produce carbon dioxide and water

The chemical equation for the combustion of methane follows:

CH_4(g)+2O_2(g)\rightarrow CO_2(g)+2H_2O(g)

  • <u>For b:</u> Butane reacts with oxygen gas to produce carbon dioxide and water.

This is also an example of combustion reaction.

The chemical equation for the combustion of butane follows:

2C_4H_{10}(g)+13O_2(g)\rightarrow 8CO_2(g)+10H_2O(g)

  • <u>For c:</u> An aqueous solution of sulfuric acid reacts with aqueous potassium hydroxide to produce potassium sulfate and water.

When an acid reacts with a base, it leads to the formation of salt and water. This reaction is known as neutralization reaction

The chemical equation for the reaction of potassium hydroxide and sulfuric acid follows:

H_2SO_4+2KOH\rightarrow K_2SO_4+2H_2O

Hence, the chemical equations are written above.
