Question

What is biogas what are the constituents and percentages are they found brainly?

Answer 1

Answer

%Ca=24.4%................by mass

Calcium nitrate has a molar mass of 164.09⋅g⋅mol−1.

We take the weighted atomic masses of each element, and divide them by this molar mass:

%Ca = 40.1⋅g⋅mol−1164.09⋅g⋅mol−1×100%=24.4%

%N = 2×14.01⋅g⋅mol−1164.09⋅g⋅mol−1×100%=17.1.%

%O = 6×16.00⋅g⋅mol−1164.09⋅g⋅mol−1×100%=58.5%

Should the individual atomic percentages SUM to 100%? Well, does they?

Answer 2

Explanation:

The material (eg sewage sludge, manure, meat and catering waste) rots in an oxygen-free environment and in the process forms a gas composed of methane and carbon dioxide. ... C) The major constituent of biogas is methane (55-70%), CO2(30-45%) and some traces of gases such as H2S and ammonia.
