A coffee cup calorimeter will not be used to directly measure the enthalpy of magnesium combustion because

yanalaym [24]

Answer:

A coffee cup calorimeter is great for measuring heat flow in a solution, but it can't be used for reactions that involve gases since they would escape from the cup. The coffee cup calorimeter can't be used for high-temperature reactions, either, because they would melt the cup.

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.
