N2 + 3H2 -> 2NH3 (Always check if it is balanced).
Ok so we have 2kg of hydrogen conver this to grams and then to moles.
2kg -> 2000g
2000g divide by R.M.M of H2
R.M.M
2H - 2 * 1 -> 2
2000/2 - 1000 moles.
Look at the ratio of H2 to 2NH3.
We see that we get 2NH3 for every H2 therefore the ratio is 1:2.
This means that we HAVE 2000 moles of 2NH3.
At stp. we know that 1 moles = 22.4 Litres
We have 2000 moles that means that we produce 44800 litres of NH3 at stp.
2000 * 22.4 - 44800
Hope this helps :).
Final answer:
The 2.0 kg of H2 after conversion to moles will react according to the balanced chemical equation N2(g) + 3H2(g) → 2NH3(g) to yield roughly 14836 liters of NH3 at standard temperature and pressure (STP). The calculation involves using the principles of stoichiometry and the molar volume of a gas at STP.
Explanation:
The chemistry topic that your question is discussing is known as stoichiometry, which involves the mathematical relationships between reactants and products in a chemical reaction. In this case, we're looking at the reaction of nitrogen gas (N2) with hydrogen gas (H2) to produce ammonia (NH3), which is described with the balanced chemical equation: N2(g) + 3H2(g) → 2NH3(g). This equation tells us that 3 moles of hydrogen react with 1 mole of nitrogen to produce 2 moles of ammonia.
Given that 1 mole of any gas occupies 22.4 liters at standard temperature and pressure (STP), and that we have 2.0 kg or 2000 g of H2, we first need to convert this mass into moles, using the molar mass of hydrogen (1.007 g/mol). So thus, 2000 g /2.014 g/mol gives us approximately 993.5 moles of hydrogen. As per the balanced equation, 3 moles of H2 yields 2 moles of NH3. Therefore, 993.5 moles of hydrogen would yield (993.5 x 2) / 3 = 662.33 moles of ammonia. Multiplying this by the molar volume at STP gives us 662.33 moles x 22.4 L/mol =14836 liters of ammonia.

Answer: Option (3) is the correct answer.
Explanation:
A molecular compound is a compound in which atoms used to share electrons and thus results in the formation of covalent bonds.
For example, is a covalent compound and hence, it is a molecular compound.
Whereas LiOH and NaI are ionic compounds as their atoms has transferred electrons.
Therefore, we can conclude that out of the given options, is the formula which represents a molecular compound.
