N2 has the optimal bond order of 3. To form N2+, one bonding electron is removed, giving a bond order of 2.5. Similarly, to form N2-, one antibonding electron is added, also giving a bond order of 2.5.
Answer:
6.
Explanation:
G, H, O, N, Na, P
There are 6 different elements listed, with O (oxygen) showing up twice.
Answer:
Ca(OH)₂(aq) ⟶Ca²⁺(aq) +2OH⁻(aq)
Explanation:
An Arrhenius base is a substance that dissociates in water to form hydroxide ions.
Ca(OH)₂(aq) ⟶Ca²⁺(aq) +2OH⁻(aq)
Calcium hydroxide dissociates completely in water to form hydroxide ions, so Ca(OH)₂ is a strong Arrhenius base.
Answer:
A-B) 94 %.
C) 17.9 %.
D) 35.8 %.
Explanation:
Hello!
A-B) In this case, since the total mass of the mixture is 3.02 g and 1.43g+1.41g=2.84 g are recovered in total, we can compute the percent recovery as shown below:
C) Here, since the solution is made up of NaCl and water, we can say that the mass of the solution is 15g+69g=84g; thus, the percent by mass would be:
D) In this case, we simply divide 26.1 g by 73.0 g in order to obtain the percent:
