Combustion! CH4, which is methane, reacts with oxygen to form carbon dioxide. (For future reference, if a compound is reacted with ONLY oxygen it is sure to be a combustion reaction)

Answer:

combustion reaction.

Explanation:

Th given chemical equation is a combustion reaction.

CH₄ or methane is a hydrocarbon. When a hydrocarbon reacts with oxygen it forms carbon dioxide and water.

All other options are incorrect.

In a single replacement reaction one element replaces another element in a compound.

Zn + H₂SO₄ = ZnSO₄ + H₂

In a double replacement reaction the cations of the reactants combines with a different anion of the reactant to form new products.

AgNO₃ + NaCl = AgCl + NaNO₃

In a decomposition reaction a complex molecule is broken down into simple molecules.

H₂O₂ = 2H₂O + O₂

If you feed 100 kg of N2 gas and 100 kg of H2 gas into a

torisob [31]

Answer : The mass of ammonia produced can be, 121.429 k

Solution : Given,

Mass of $N_2$ = 100 kg = 100000 g

Mass of $H_2$ = 100 kg = 100000 g

Molar mass of $N_2$ = 28 g/mole

Molar mass of $H_2$ = 2 g/mole

Molar mass of $NH_3$ = 17 g/mole

First we have to calculate the moles of $N_2$ and $H_2$ .

$\text{ Moles of }N_2=\frac{\text{ Mass of }N_2}{\text{ Molar mass of }N_2}=\frac{100000g}{28g/mole}=3571.43moles$

$\text{ Moles of }H_2=\frac{\text{ Mass of }H_2}{\text{ Molar mass of }H_2}=\frac{100000g}{2g/mole}=50000moles$

Now we have to calculate the limiting and excess reagent.

The balanced chemical reaction is,

$N_2+3H_2\rightarrow 2NH_3$

From the balanced reaction we conclude that

As, 1 mole of $N_2$ react with 3 mole of $H_2$

So, 3571.43 moles of $N_2$ react with $3571.43\times 3=10714.29$ moles of $H_2$

From this we conclude that, $H_2$ is an excess reagent because the given moles are greater than the required moles and $N_2$ is a limiting reagent and it limits the formation of product.

Now we have to calculate the moles of $NH_3$

From the reaction, we conclude that

As, 1 mole of $N_2$ react to give 2 mole of $NH_3$

So, 3571.43 moles of $N_2$ react to give $3571.43\times 2=7142.86$ moles of $NH_3$
