Answer:
a. 2nd order reaction.
b. The first step is the slow step.
Explanation:
r = k[NO][Cl₂]
a. The reaction is first-order in [NO] and first-order in [Cl₂], so it is second-order overall.
b. The first step is the slow step, because it predicts the correct rate law.
c. is wrong. Doubling [NO] would double the rate, because the reaction is first-order in [NO].
d. is wrong. Cutting [Cl₂] in half would halve the rate, because the reaction is first-order in [Cl₂].
e. is wrong. The molecularity is two, because two particles are colliding.
f. is wrong. Both steps are bimolecular.
Answer:
Thus, the joules of heat absorbed when 70.0 grams of water is completely vaporised at its boiling point are 158,200.
Answer: a. 6(3x2=6)
B. 4(4x1=4)
C. 6(4(1)+2(1)=4+2=6
D. 4
E. 6(3(2)=6)
F. 4(2(1)+2(1)[2+2=4)
G. 5(5(1)=5)
H. 4(2(1)+2(1)=2+2=4)
Explanation:
Coordination number= no of ligands
= No of ligands X denticity
Denticity is nothing but type of ligands like mono,do and tetradentate ligands.
The bond is highly polar is the scientific claim about the bond in the molecular compound HF is most likely to be true.
The term polar means that there is separation of charges, the bonds will be the more polar the greater the difference in electronegativity between the bonded atoms.
- In hydrogen fluoride, for example, F is more electronegative than H because its nucleus, with 9 positive charges, attracts e-shares with H more strongly than the nucleus of H, with only one positive charge.
- Therefore, the e- shared by covalence will be closer to F than to H and the molecule forms a permanent dipole.
Therefore, we can conclude that the bond is highly polar is the scientific claim about the bond in the molecular compound HF is most likely to be true.

Answer:
halogens
Explanation:
Elements that are nonmetals tend to gain electrons and become negatively charged ions called anions
