Answer:
1.
CH4 + Cl2 → CH3-Cl + HCl
2CH3-Cl +2Na → C2H6
2.
CH3-CH2-OH ---(conc. H2SO4)----> CH2=CH2 + H2O
Explanation:
1. Conversion of methane to ethane
Step 1 - Treat methane with chlorine gas presence of ultraviolet light
CH4 + Cl2 → CH3-Cl + HCl
Step 2 - Treat chloromethane formed in step 1 with the sodium metal and dry ether (Wrutz synthesis)
2CH3-Cl +2Na → C2H6
2. On treating ethanol with excess of concentrated sulfuric acid, it converts into ethene
CH3-CH2-OH ---(conc. H2SO4)----> CH2=CH2 + H2O
Answer:
Molar ratio of the compound is 1:1 and the type of hydrate is Mono hydrate.
Explanation:
From the given,
Mass of sodium carbonate
= 8.85 g
Loss mass
= 1.28 g
Actual weight of sodium carbonate = 8.85 g - 1.28 g = 7.57 g


Therefore, the compound has only one water molecule.
Molecular formula of the compound is
an name of the compound is <u>sodium carbonate mono hydrate.</u>
Hence, the type of the compound is Mono hydrate.
43.62m
Explanation:
Given parameters:
Energy = 8550J
Mass of bell = 20kg
Unknown:
Height of the bell = ?
Solution:
As this state, the bell possesses potential energy. Potential energy is the energy at rest in a body. It is due to the position of the body.
Potential energy = m g h
m is the mass of the body
g is the acceleration due to gravity of the body
h is the height of the body
The unknown is h and we should solve for it.
g = 9.8m/s²
Input the variables;
8550 = 20 x 9.8 x h
h = 43.62m
