What happens to the limewater if the gas is present?
If a gas is present in limewater, such as carbon dioxide, it will react with the limewater to form a white precipitate of calcium carbonate. This reaction causes the limewater to become cloudy or milky in appearance. It is a common test for the presence of carbon dioxide gas.
What happens to limewater at the end of an experiment?
At the end of an experiment, limewater will turn cloudy if carbon dioxide was present in the environment, causing it to react with the calcium hydroxide in limewater to form calcium carbonate, which is insoluble and appears as a white precipitate. If there was no carbon dioxide present, limewater will remain clear.
Does methane react with sodium?
Yes, methane does not react with sodium under normal conditions because methane is a stable molecule and does not readily undergo chemical reactions with alkali metals like sodium.
Why does boron trifluoride not react with methane?
Boron Trifluoride has only 6 electrons in it's outer shell, and is more stable with 8. Therefore, it will react with molecules that have a free electron pair. Methane does not have a free pair, so it doesn't react.
What effect does oxygen do on limewater?
Oxygen does not have a direct effect on limewater. Limewater is a solution of calcium hydroxide, and when exposed to carbon dioxide, it forms calcium carbonate, turning the limewater milky. Oxygen does not directly interact with the limewater in this chemical reaction.
Why do we test the gas given off with limewater?
Limewater (calcium hydroxide) react with carbon dioxide and form insoluble, white precipitate of calcium carbonate.

If there was no carbon dioxide present, limewater will remain clear.
What would be the effect of the hydrogen on limewater?
Hydrogen gas does not directly react with limewater (calcium hydroxide solution) to produce a visible change. Limewater is typically used to test for the presence of carbon dioxide, which would cause the solution to turn milky due to the formation of insoluble calcium carbonate.
What happens when limewater is added to unsaturated compounds?
When limewater (a dilute solution of calcium hydroxide) is added to unsaturated compounds, such as alkenes or alkynes, a chemical reaction can occur if the unsaturated compound contains functional groups that can react with calcium hydroxide. For example, if an alkene undergoes a reaction with limewater in the presence of sufficient heat or catalysts, it may lead to the formation of alcohols or other products. However, in general, limewater does not react significantly with most unsaturated hydrocarbons under normal conditions.
What are the 2 main products when methane and chlorine react?
Chloromethane is the product that is formed when methane and chlorine react with each other. Dichloromethane is another product that can also be formed when methane and chlorine react.
What is observed when methane is mixed with chlorine water left in the dark?
Methane does not react with chlorine in the dark.
Does methane react with sodium?
Yes, methane does not react with sodium under normal conditions because methane is a stable molecule and does not readily undergo chemical reactions with alkali metals like sodium.
Why does boron trifluoride not react with methane?
Boron Trifluoride has only 6 electrons in it's outer shell, and is more stable with 8. Therefore, it will react with molecules that have a free electron pair. Methane does not have a free pair, so it doesn't react.
Why methane does not react with oxygen at room temperature?
Energy! Methane is a stable molecule and oxygen is almost (pretty) stable. The there is sufficient energy, called activiation energy, then the two gases will react
Which gas does methane react with when natural gas is burned?
Oxygen
Does methane reacts with chlorine in dark?
Theotically, methane can't react with Cl2 in shade as UV light is required to initiate the substitution reaction. Only when there is Cl2 can the C-H bond be broken. However, alkene can react directly with Cl2 due to hydrohalogenation.
