Answer:
120°
Explanation:
Valence electrons of boron = 2
Valence electrons of chlorine = 7
The total number of the valence electrons = 3 + 3(7) = 24
The Lewis structure is drawn in such a way that the octet of each atom in the molecule is complete. So,
The Lewis structure is:
There is no lone pair involved, so, It is of type AB₃.
According to the theory, the atoms will form a geometry in such a way that there is minimum repulsion and maximum stability.
So, it is of triangular shape, with bond angle , 120 ° .
Plz help me I need help to but in math plzz I have 2 miplz help me
Answer:
1.03M
Explanation:
mass/molar mass = moles of solution
50 g / (80+1) = 0.617 mol HBr
molarity*volume = moles
M*0.600 L = 0.617 mol
M = 0.617/0.600 = 1.03 M
Answer:
3850g
Explanation:
Solubility is the amount of solute dissolved in a solvent.
Solubility is mass of solute÷mass of solvent
The solvent is 35grams
Solute?
Solubility of solute is 110
110=x/35
= 110 × 35
The amount of residue solute is 3850g
I think the answer is A or anything with Barometer
