Answer:
0.228 mol FeO
Explanation:
2FeS2 + 5 O2----> 2FeO + 4SO2
from reaction 5 mol 2 mol
given 0.57 mol x
x = 0.57*2/5 = 0.228 mol FeO
13.420728 cm3 (cubic centimeters)
So the answer choice would be (A) if you were rounding to the nearest tenth
Answer: 3.87M of HI remains after 27.3 s
Explanation:
Using the Second order decomposition equation of
1/[H]t =K x t +1/[A]o
Given initial concentration ,[A]o = 4.78M
time, t = 27.3 s
rate of constant , k= 1.80 x 10^-3 M-1s-1
1/[H] t= 1/[A] t= concentration after time, t=?
SOLUTION
1/[A] t =kt +1/[A]o
1/[A] t =(1.80 x 10^-3 (27.3)+1/4.78
0.04914+0.2092=0.2583
1/[A] t =0.2583
[A] t =1/0.2583= 3.87M
Answer:
Vanadium (VI) Phosphide
Explanation:
Vanadium has a 6+ charge for this compound, so there needs to be two phosphorus atoms to satisfy the charges. This is an ionic compound as well so the roman numerals need to be present.
