Answer:
The correct answer is option 1 "F(2-) "less than" C2(2+) "less than" O(2-) "less than" N(2-)".
Explanation:
Bond order is a term used in chemistry to identify the number of electrons involved in making the bonding between two or more atoms in a molecule. Bond order is equal to half the difference between the number of bonds in the atoms minus the number of antibonds. Therefore, the correct order of bond order from smallest to largest is as follows:
1. F(2-): equals to 0.5 (it has 8 bonds and 7 antibonds)
2. C2(2+): equals to 1 (it has 4 bonds and 2 antibonds)
3. O(2-): equals to 2 (it has 8 bonds and 4 antibonds)
4. N(2-): equals to 2.5 (it has 8 bonds and 3 antibonds)
Answer:
<h2>mass = 19.98 g</h2>
Explanation:
To find the mass of 1.11 mol of H2O we must first find it's molecular mass after that we use the formula
<h3>m = M × n</h3>
where
m is the mass
M is the molecular mass
n is the number of moles
From the question
n = 1.11 mol
Taking
M( H) = 1 g/mol , M(O) = 16 g/mol
We have
M( H2O) = 2 + 16 = 18 g/mol
So we have
m = 1.11 × 18
We have the final answer as
<h3>mass = 19.98 g</h3>

I think the answer would be C. They are unreactive.
