Answer: Option (d) is the correct answer.
Explanation:
A matter that is made from only one type of atom is called an element.
For example, a small ball of sodium metal will contain all the atoms of the element sodium.
Whereas both compound and molecule contains different atoms. For example, NaCl compound contains atoms of sodium and chlorine.
On the other hand, a material also contains different atoms.
When a solid turns into a liquid
Example: Ice cube melts into water
Answer:
7,052.6secs
n of Cu = +2
R.A.M of Cu = 64g
m = 7.25g
I = 3.1A
F = 96500
nF = R.A.M
It = m
2*96500 = 64
3.1*t = 7.25
1,399,250 = 198.4t
t = 7,052.6secs
