"how many grams of h2 are needed to produce 13.09 g of nh3

Vadim26 [7]

MH₂: 2 g/mol
mNH₃: 17 g/mol
...............................
3H₂ + N₂ ---> 2NH₃
6g......................34g

6g H₂ ---- 34g NH₃
Xg -------- 13,09g
X = (6×13,09)/34
X = 2,31g H₂

Consider the reaction C2H4(g) + H2O(g) --> CH3CH2OH(g)

arsen [322]

Answer:

K = 361.369

Explanation:

C2H4(g) + H2O(g) → CH3CH2OH(g)

∴ ΔG°f(298.15K) CH3CH2OH(g) = - 174.8 KJ/mol

∴ ΔG°f(298.15) C2H4(g) = 68.4 KJ/mol

∴ ΔG°f(298.15) H2O(g) = - 228.6 KJ/mol

⇒ ΔG°f(298.15) = - 174.8 - ( - 228.6 + 68.4 ) = - 14.6 KJ/mol

K = e∧(-ΔG°f / RT)

∴ R = 8.314 E-3 KJ/mol.K

∴ T = 298.15 K

⇒ K = e∧(-(-14.6)/((8.314 E-3)(298.15)))

⇒ K = e∧(5.889)

⇒ K = 361.369

Make a prediction. How do you think adding other substances to the water would affect its

Nikitich [7]

Hi there
My prediction is that as you put substances is that is will delay the boiling point of the water as it is heated
Also I found a answer on study.con but it requests that I do a email but I figured you may need it in the future

If you have 10 protons and 11 neutrons, in a electrically neutral atom, How many electrons would you have?

LUCKY_DIMON [66]

Answer:

Well, you'd have 1 electron more than protons (since there are 10 protons and 11 electrons). So the previously neutral ion has now become an ion with a -1 charge
