Answer:
Fact: There’s only one letter that doesn’t appear in any U.S. state name
And that is Q
Explanation:
Hello!
To find the number of atoms in 2.822 moles of nickel, we need to multiply it by Avogadro's number. Avogadro's number is 6.02 x 10^23 atoms.
2.822 moles x (6.02 x 10^23) ≈ 1.698844 x 10^24
Therefore, there are about 1.70 x 10^24 atoms (according to the number of significant figures) in 2.822 moles of nickel.

Answer: The order with respect to
is 1.
Explanation:
Rate law says that rate of a reaction is directly proportional to the concentration of the reactants each raised to a stoichiometric coefficient determined experimentally called as order.
![NH_4^++NO_2^-\rightarrow N_2+2H_2O](https://tex.z-dn.net/?f=NH_4%5E%2B%2BNO_2%5E-%5Crightarrow%20N_2%2B2H_2O)
k= rate constant
x = order with respect to ![NH_4^+](https://tex.z-dn.net/?f=NH_4%5E%2B)
y = order with respect to A![NO_2^-](https://tex.z-dn.net/?f=NO_2%5E-)
n = x+y = Total order
From trial 1:
(1)
From trial 2:
(2)
Dividing 2 by 1 :
therefore x= 1
Thus order with respect to
is 1.
