Answer:
Hi, There!
Based on your understanding, what is Big bang Theory?
- <em>The Big Bang is an idea about the history of the Universe, the history of space and time and matter and Energy.</em>
Therefore, I Hope this helps!
Answer:
The answer is A. Lithium and Sodium
I am not sure about my answer, but I think that it's density allows it to fall to the ground/floor.
Answer:
Since ΔEN > 0, the bond is covalent polar and the molecule is polar (dipole). Since ΔEN > 0, the bond is covalent polar and the molecule is polar (dipole). HI and ClF interact through a dipole-dipole force

Answer:
We have:
M

→

)
LHS
Mg= 1
H= 1
Cl= 1
RHS
Mg= 1
Cl=2
H=2
To make Cl and H have 2 on both sides, we place a 2 in front of the HCl

LHS
Mg=1, H=2, Cl=2
RHS
Mg=1, H=1, Cl=2
Thus the equation is balanced and the coefficient of Mg is 1, which is understood so it is not written in the final equation.
