Answer:
d. 8
Explanation:
Valence electrons of oxygen = 6
Valence electrons of hydrogen = 1
The total number of the valence electrons = 6 + 2(1) = 8
The Lewis structure is drawn in such a way that the octet of each atom and duet for the hydrogen in the molecule is complete.
In the water molecule,
<u>Oxygen has 2 bond pairs and two lone pairs which means that the total electrons in the valence shell is 8.</u>
Answer:
Benzene: 37.5 Torr
Methylbenzene: 12.5 Torr
Explanation:
By Raoult's Law, each substance in a gas mixture contributes to the total pressure of the mixture proportionally to their respective mole fraction. So,
Ppartial = x*P°
Where x is the mole fraction (0.5 for each one because it's equimolar), and P° is the vapor pressure.
Benzene: Ppartial = 0.5 * 75 = 37.5 Torr
Methylbenzene: Ppartial = 0.5 * 25 = 12.5 Torr
Answer:
The answer to your question is 8,32 L
Explanation:
Data
Pressure 1 = 104.5 kPa
Volume 1 = 3.4 L
Pressure 2 = 42.7 kPa
Volume 2 = ?
Formula
- To solve this problem use the Boyle's law.
P1V1 = P2V2
- Solve for V2
V2 = P1V1 / P2
- Substitution
V2 = (104.5)(3.4) / 42.7
-Simplification
V2 = 355.3 / 42.7
- Result
V2 = 8.32 L
Answer:
2 the mass is greater than 10.0gram
Explanation:
2 the mass is greater than 10.0gram
The answer for that is 16, math right?
