False... The number of electrons in the outer shell of the atom of the element determines it's reactivity. <span />
Greater absolute charge
- This is because ionic bond results from stronger electrostatic forces of attraction.
- The higher the value of charges q₁ and q₂ the stronger will be the ionic bond.
Answer:
Explanation:
1. Calculate the initial moles of acid and base
2. Calculate the moles remaining after the reaction
OH⁻ + H₃O⁺ ⟶ 2H₂O
I/mol: 0.0053 0.005 00
C/mol: -0.00500 -0.005 00
E/mol: 0.0003 0
We have an excess of 0.0003 mol of base.
3. Calculate the concentration of OH⁻
Total volume = 53 mL + 25.0 mL = 78 mL = 0.078 L
Answer:
1m×268.0L/22.4L=11.9m
Explanation:
there are 11.9 moles of nitrogen monoxide are present
Answer: New concentration of is 0.23 M.
Explanation:
The given data is as follows.
Moles of = 0.06 mol
Moles of = 0.08 mol
Therefore, moles of added are as follows.
Moles of =
= 0.003125 mol
Now, new moles of = 0.06 + 0.003125
= 0.063125
Therefore, new concentration of will be calculated as follows.
Concentration =
= 0.23 M
Thus, we can conclude that new concentration of is 0.23 M.
