Answer:
The F₂ molecule is formed by single bonds alone.
Explanation:
The octate rule dictates that atoms have a preference to have 8 electrons in their valence shells. Considering this rule we can analyse how the electrons are distributed in the molecules and see how the atoms bond to obbey the rule.
The fluorine atom has 7 electrons in its valence shell. This means that it needs one more electron to reach stability. Therefore, when two fluorine atoms combine, they share one electron each, forming a single bond.
The atoms of the other molecules need more than one electron to reach the octate, therefore they need to share more electrons, forming double and triple bonds.
This is right
Reduce the concentration of NICO4
This is one of the ideal gas laws. Presumably the pressure remains the same so it is not part of the givens.
Formula
V / T = V1 / T1
Givens
- V = 56.05 mL
- T = 315.1 degrees Kelvin
- V1 = x
- T1 = 380.5 degrees Kelvin
Solution
56.05/315.1 = x/380.5 Simplify the left.
0.1779 = x / 380.5 Multiply both sides by 380.5
0.1779 * 380.5 = 380.5x/380.5
67.68 mL = x This is your answer
