Answer:
128g of Li, will react in this reaction
Explanation:
Before to start working, we need the reaction:
N₂ and Li react, in order to produce Li₃N (lithium nitride)
N₂ + 6Li → 2Li₃N
1 mol of nitrogen reacts with 6 moles of lithium
We convert the mass of N₂ to moles → 86.1 g . 1 mol/ 28g = 3.075 moles
1 mol of N₂ reacts with 6 mol of Li
Therefore, 3.075 moles of N₂ will react with 18.4 moles of Li
We conver the moles to mass → 18.4 mol . 6.94g / 1mol = 128 g

I don't know what the choices are, but take a picture of the choices
<span>One degree Celsius indicates the same temperature change as one </span>
Sugar dissolves and is spread throughout the glass of water<span>. The </span>sand<span> sinks to the bottom. The sugar-</span>water<span> is a homogeneous mixture while the </span>sand-water<span> is a heterogeneous mixture. Both are mixtures, but only the sugar-</span>water<span> can also be called a </span>solution. i got this from :<span>www.chem4kids.com/files/matter_solution.html
