Answer:
2-pentyne
Explanation:
To name hydrocarbons, you first you have to identify the longest carbon chain. There are 5 carbons in this chain, so we know the name is "pent".
You then have to identify the presence of any double or triple bonds. If double bonds, it is an alkene, if triple bonds, it is an alkyne. In this case there is a triple bond, so we know the hydrocarbon is pentyne.
You then number the chain to give the lowest number to the triple bond. It could either be 4 (countnig carbons from left to right) or 2 (from right to left). Therefore, the answer is 2-pentyne.

Answer:
4 moles
Explanation:
The balanced equation for the reaction is given below:
N2 + 3H2 → 2NH3
From the balanced equation above,
1 mole of N2 produced 2 moles of NH3.
Therefore, 2 moles of N2 will produce = 2x2 = 4 moles of NH3.
Therefore, if we start with 2 moles of N2, then, we will produce 4 moles of NH3
