P = 1.5atm ≈ 1519.88hPa
V = 8.56L
R = 83.1 [hPa*L] / [mol*K]
T = 0°C =273K
pV = nRT |:RT
n = pV / RT
n = [1519.88hPa*8.56L] / [83.1 [hPa*L] / <span>[mol*K] * 273K]
n </span>≈ <u>0.57mol</u><span><u> </u></span>
Answer:
40 moles of Na2CO3 has the mass of = 105.98×40 = 4239.2 grams = 4.2392 kilograms.
Explanation:
Answer:
General chemical equation
2 M + 3 X₂ → 2 MX₃
Explanation:
When metal reacts with halogens metal halide as a product obtained.
Now oxidation state of metal assume (+3)
and oxidation state for halogen = (+1)
So formula of the metal halide is (MX₃)
Denote the metal as M and halogen as X
the balanced chemical equation
2 M + 3 X₂ → 2 MX₃
So the resulted general equation when metal react with halogen is
2 M + 3 X₂ → 2 MX₃
