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
0.032 Ms = 3.2 × 10^4 s
<em>Step 1</em>. Convert the number to scientific notation.
0.032 = 3.2 × 10^(-2)
<em>Step 2</em>. Convert the measurement to base units.
3.2 × 10^(-2) Ms × (10^6 s/1 Ms) = 3.2 × 10^4 s
Answer: The answer is frequency.
Explanation: If the wavelength is long, the frequency will be low. If the wavelength is short, the frequency will be high.
