Using the formula
V1P1=V2P2
where V1=1.0
V2=4.0
P1=1.2
P2=?
P2=V1P1/V2
P2=1.0*1.2/4.0
P2=0.3 atm
Answer:
The identity of an element depends on the number of protons, neutrons, and electrons.
Explanation:
Answer:
An atom is the smallest unit of ordinary matter that forms a chemical element.
Matter is composed of very tiny or microscopic particles called "Atom".
(According to Dalton atomic theory some of his principles were wrong and later was corrected but the definition of an atom was right in his theory).
Answer:
1.38 x 10^-18 J
Explanation:
q = - 1.6 x 10^-19 C
d = 5 x 10^-10 m
the potential energy of the system gives the value of work done
The formula for the potential energy is given by
So, the total potential energy of teh system is
As all the charges are same and the distance between the two charges is same so the total potential energy becomes
K = 9 x 10^9 Nm^2/C^2
By substituting the values
U = 1.38 x 10^-18 J
