Answer:
14 mol
Explanation:
CH4(g) + 2O2(g) -------» CO2(g) + 2H2O(g)
from reaction 1 mol 2 mol
given 7 mol x mol
x = (7*2)/1 = 14 mol
Answer: All of the parts of a series circuit-power source, wires, and devices-are connected along the same pathway, All of the parts of a series circuit-power source, wires, and devices-are connected along the same pathway. These two are correct.
Explanation:
Answer: None of the given options show polymer made up of H₂C=CH-CN (Acrylonitrile).
Explanation: Acrylonitrile (H₂C=CH-CN) which is a monomer on self linkage results in a large chain polymer called as
Polyacrylonitrile.
The structure of Polyacrylonitrile is as follow,
--(H₂C-CHCN-)n--Where n shows the number of Acrylonitrile units joined together in the formation of Polyacrylonitrile. This polymerization reaction can take place by different mechanisms including free radical mechanism, acid catalyzed addition or base catalyzed addition reaction.
The polymerization is shown below,
Answer:
C
Explanation:
electronic waves transmits energy but mechanical waves require a medium in order to transport their energy from bgg one place to another.
