Answer:
Pauli exclusion principle
Explanation:
No two fermions can have the same set of quantum numbers is called the Pauli exclusion principle. And a electron is a fermion.
There are four basic quantum numbers
Principle quantum number n
the angular momentum quantum number l
magnetic quantum number m_l
and electron spin quantum number m_s
Not trying to be mean plzz dont report me but I don’t see the question
Answer: A BaBr2
Explanation:
On the left side of the equation, the superscript 2 is applied to both sodium AND bromine. That means you need 2 bromine on the right. Also on the left side, the 2 AFTER chlorine only applies to the chlorine so there’s only one barium. What you have on the left has to balance with what you have on the right.
Answer:
The charge on point A is = 2.4 × C
The charge on point B is = 1.2 × C
Explanation:
Given data
Distance (r) = 0.19 m
Magnitude of the charge on A is twice that of the charge on B i.e.
F = 46 N
We know that force between the charges is given by
= 1.2 × C
= 2 ×
= 2 × 1.2 ×
= 2.4 × C
Therefore the charge on point A is = 2.4 × C
The charge on point B is = 1.2 × C
B. Energy is added to the cube causing particles to speed up and spread out, causing the cube to melt.
