I think that the empirical formula is mgcl2
6 Li + N2 = 2 Li3N
6 moles Li ---------> 2 moles Li3N
0.24 moles Li ------> ?
moles Li3N = 0.24 * 2 / 6
= 0.48 / 6
= 0.08 moles of li3N
hope this helps!.
<span>Determining the number chloride molecules that will result from this reaction requires we first determine the number of moles of arsenic and the number of moles of chlorine on hand.
1.587 grams of arsenic divided by its atomic weight of 74.92 grams per mole results in 0.0212 moles.
We do the same for chlorine. 2.755 grams of chlorine divided by 35.45 grams per mole gives us 0.106 moles.
0.106 moles divided by .0212 moles equals 5; therefore, the simplest formula of the chloride produced will be AsCl</span>₅<span>.</span>
Sorry I accidentally touched it
Answer:
This can be solved using Dalton's Law of Partial pressures. This law states that the total pressure exerted by a gas mixture is equal to the sum of the partial pressure of each gas in the mixture as if it exist alone in a container. In order to solve, we need the partial pressures of the gases given. Calculations are as follows:
Explanation:
P = 3.00 atm + 2.80 atm + 0.25 atm + 0.15 atm
P = 6.8 atm
3.5 atm = x (6.8 atm)
x = 0.51
