Answer:

Using the proportions of the amount of the molecules, we can convert from any reagent or product to any other reagent or product. In the context of this reaction, for every mole of N2 and every 3 moles of H2 we obtain 2 moles of NH3.

Explanation:

Hydrogen is the limiting reactant. In other words, Hydrogen will run out before Nitrogen because it takes 3 mole of H2 and just 1 mole of N2 to make 2 mole NH3. What is the greatest amount of MgO (in moles) that can be made with 7.8 moles of Mg and 4.7 moles of

The Reaction is spontaneous when temperature is 430 K. Hence, Option (C) is correct.

<h3></h3><h3>What is Spontaneous reaction ?</h3>

Reactions are favorable when they result in a decrease in enthalpy and an increase in entropy of the system.

When both of these conditions are met, the reaction occurs naturally.

Spontaneous reaction is a reaction that favors the formation of products at the conditions under which the reaction is occurring.

According to Gibb's equation:

ΔG = ΔH - TΔS

ΔG = Gibbs free energy

ΔH = enthalpy change = +62.4 kJ/mol

ΔS = entropy change = +0.145 kJ/molK

T = temperature in Kelvin

ΔG = +ve, reaction is non spontaneous
ΔG = -ve, reaction is spontaneous
ΔG = 0, reaction is in equilibrium

ΔH - TΔS = 0 for reaction to be spontaneous

T = ΔH / ΔS

Here,

T = 500K

Thus the Reaction is spontaneous when temperature is 500 K.

The equation for the formation of water from hydrogen gas and oxygen gas is 2H2+O2→2H2O.

inn [45]

Answer:

180g

Explanation:

H:1 O:16

2H2+O2 → 2H2O

2 2(16) 2(1)+(16)

32 18

Now,

32g of O → 2(18)g of H2O

160g of O → 2(18)g divides by 32g times 160g

=180g
