Question

Write reactions for the following.

a) When methane is treated with chlorine gas.
b) When sodium hydroxide is treated with carbon dioxide.

c) When methane is burn in presence of oxygen.​

Answer 1

Answer:

When methane reacts with chlorine a substitution reaction occurs and the organic product is chloromethane.

2 NaOH (s) + CO2 (g) →Na2CO3 (aq) + H2O (l) This means that solid reagent grade sodium hydroxide is not pure enough to weigh and use directly. Furthermore, the carbonate ion interferes in acid-base titrations because 1) it is a weak base, and 2) it tends to make the color change at the end point less sharp.

If you test a reaction that releases heat, the temperature of the water will increase. Hydrocarbon fuels like methane (CH4) burn in the presence of oxygen to produce carbon dioxide and water. This process of combustion releases energy.

Answer 2

$\tt\red {answer}$

1. When methane reacts with chlorine a substitution reaction occurs and the organic product is chloromethane.
2. 2 NaOH (s) + CO2 (g) →Na2CO3 (aq) + H2O (l) This means that solid reagent grade sodium hydroxide is not pure enough to weigh and use directly. Furthermore, the carbonate ion interferes in acid-base titrations because 1) it is a weak base, and 2) it tends to make the color change at the end point less sharp.
3. Methane, CH4, burns in the presence of oxygen to form water vapor and carbon dioxide. ... For each molecule of methane burned, carbon-hydrogen single bond(s) are broken. Also, because molecule(s) of oxygenare utilized in the balanced equation,oxygen-oxygen double bond(s) are broken.
