Why calcium is not used in the lab preparation of hydrogen?
Calcium is not used in the lab preparation of hydrogen because it reacts with water to form calcium hydroxide and hydrogen gas, making it an inefficient method for producing pure hydrogen. Other methods such as using metals like zinc or aluminum are preferred for lab preparation of hydrogen as they do not form unwanted byproducts.
Methane and ethane separating method?
Methane and ethane can be separated through a process called fractional distillation, which takes advantage of their different boiling points. The mixture is heated in a column, and as the temperature increases, the components with lower boiling points vaporize first and are collected at different levels of the column. This allows for the separation of methane and ethane based on their boiling points.
Is ethane a allotrope?
No, ethane is not an allotrope. Allotropes are different structural forms of the same element, while ethane is a compound composed of carbon and hydrogen atoms.
How many carbon atoms are contained in 5.50 gms of ethane?
30 g of ethane will have 6.023 x 1023 molecules of ethane So, 5.5 g will have 1.104 x 1023 molecules of ethane Since there are two carbon atoms, in one molecule of ethane, 5.5 g of ethane will have 2.208 x 1023 atoms of carbon.
What is the valency of carbon in ethane?
Valency of carbon is 4. It remains 4 in ethane too.
Why ethane is an important industrial chemical?
Ethane applications are: - precursor in ethylene preparation (the most important use) - refrigerant - fuel

How do you prepare methanal from ethanal?
Monohalogenation of methane, followed by Wurtz reaction.
Why is good preparation in lab investigations?
good preparation is good for lab investigations as there are toxic gases in the labs hence someone should know well on the apparatus to use to take precise action

How can we prepare ethane from sodium propanoate?
Ethane can be prepared from sodium propanoate through a decarboxylation reaction. When sodium propanoate is heated with soda lime (a mixture of sodium hydroxide and calcium oxide), it undergoes decarboxylation to produce ethane. The reaction involves the removal of a carbon dioxide molecule from sodium propanoate, yielding ethane as the primary product. This method effectively converts the carboxylate group into an alkane.
