Atom is defined as the smallest part of an element which has chemical properties.It consist of a nucleus having combinations of neutrons and protons bound to the nucleus.
So Electrons cannot travel in definite circular pathways around the nucleus.
hence the right option is <span>C) Electrons travel in definite circular pathways around the nucleus</span>
Answer:
Both
Explanation:
The combined gas law is also known as the general gas law.
From the ideal gas law we assume that n = 1;
So;
PV = nRT
and then;
=
If we cross multiply;
P₁V₁T₂ = P₂V₂T₁
So;
T₁ =
Also;
V₂ =
So from the choices both are correct
The ratio of moles of AI(NO3)3 to moles Na2CO3 in the reaction is 2:3
In the reaction 2 moles of AI(NO3)3 reacted with 3 moles Na2CO3 so the ratio of the moles is 2 is to 3 represented as 2:3
