Answer:
barium oxide < calcium oxide< sodium chloride < lithium chloride < aluminum oxide
Explanation:
The lattice energy can be defined as the change in internal energy accompanying the formation of a single mole of an ionic solid from its gaseous constituents at 0 K.
The lattice energy depends on the relative sizes of cations and anions in the compound. The smaller the cations and anions, the greater the lattice energy.
If we look as the proposed order of increasing lattice energy of the compounds; barium oxide < calcium oxide< sodium chloride < lithium chloride < aluminum oxide, we will notice that it follows the order of decrease in the sizes of both the ions, Ba^2+ > Ca^2+ > Na+ >Li+ > Al^3+.
The smaller the ions involved, the greater the lattice energy as one can see from the order listed above.

We first need to calculate how much energy is needed to ionize a single atom. So divide the kilojoules/mol energy value by avogadro's number.
342 kj/mol / 6.0221409x10^23 = 5.67904x10^-19 Joules
So we need a photon with 5.67904x10^-19 Joules of energy. The equation to express the energy of a photon is
E = hc/w
where
h = Planck constant (6.626070040Ă—10â’34 Js)
c = speed of light (299792458 m/s)
w = wavelength of photon
Solving for w
E = hc/w
Ew = hc
w = hc/E
Substituting known values
w = 6.626070040Ă—10^â’34 Js * 299792458 m/s / 5.67904x10^-19 J
w = 1.9864458x10^-25 Jm / 5.67904x10^-19 J
w = 3.497855x10^-7 m
w = 3.50x10^-7 m
w = 350 nm</span>
The nearest dollar would be 1 dollar because 3 is closer to 1 than to 5 or to 10 so therefor you would be rounding down.
Answer:
N₂ + 3H₂ → 2NH₃
Explanation:
Chemical equation:
N₂ + H₂ → NH₃
Balanced chemical equation:
N₂ + 3H₂ → 2NH₃
Step 1:
N₂ + H₂ → NH₃
left hand side: Right hand side
N = 2 N = 1
H = 2 H = 3
Step 2:
N₂ + 3H₂ → NH₃
left hand side: Right hand side
N = 2 N = 1
H = 6 H = 3
Step 3:
N₂ + 3H₂ → 2NH₃
left hand side: Right hand side
N = 2 N = 2
H = 6 H = 6
It is very salty and can dehydrate you it is considered sodium that’s all I know
