Water can be split into O2 and H2 gas
HA +BOH→BA+H2O
neutralisation reaction for monobasic acid monoacidic base
Electromagnetic wave travels faster through air than metal.
Option A
<u>Explanation:</u>
There are different kinds of wave energy. The most significant are electromagnetic and mechanical waves. The mechanical waves propagate through the medium by transfer of energy by vibrating of particles in medium.
So, the more number of particles present in the medium, the more fast the mechanical wave can propagate. So the mechanical waves travel faster in metals consisting of more number of free charge carriers. But electromagnetic waves does not need any of the medium to propagate. So it can travel faster in air than in metals.
The following are the answers:
=oxygen equals to a charge of 2-
number of atoms is -24
=Mn equals to the charge of +3
Mn= 3+3x-24=0
let x be the charge of Cl, so:
23-3=3x
20/3=x
=6.67 or 7
x= 7
= Cl has a charge of +7
You are right about your answers
