Answer:
The answer to your question is 42.9 g of Ca
Explanation:
Data
mass of Ca = ?
mass of N₂ = 10 g
Balanced chemical reaction
3Ca + N₂ ⇒ Ca₃N₂
Process
1.- Calculate the molar mass of the reactants.
Ca = 3(40) = 120 g
N₂ = 2(14) = 28 g
2.- Calculate the mass of Calcium using proportions and the molar mass of the reactants.
120 g of Ca ---------------- 28 g of N₂
x ---------------- 10 g of N₂
x = (10 x 120) / 28
x = 1200 / 28
x = 42.9 g of Ca
There are 2 peaks are in the proton spin decoupled 13C NMR spectrum of 1,3,5-trinitrobenzene .
The 13C NMR spectrum give the peak which is directly about the carbon skeleton not just the proton attached to it . The number of signals tell us how many different carbons or set of equivalent carbons . The splitting of a signal tells us how many hydrogens are attached to each carbon.
In 1,3,5-trinitrobenzene molecule , there are 2 peaks are in the proton spin decoupled 13C NMR spectrum three carbon give one signal and another three carbon give another one signal .

It decreases as temperature is indirectly proportional to volume
Answer:
The two elements are FLUORINE AND CHLORINE. These two elements have similar characteristics because they belong to the same group in the periodic table. On the periodic table, elements with similar properties are grouped together in the same group. Both chlorine and fluorine belongs to the halogen group.

Hope it helps, some how.
Answer:
16.9 mol
Explanation:
8Al + 3Fe₃O₄ ⟶ 4Al₂O₃ + 9Fe
You want to convert moles of Fe₃O₄ to moles of Al.
The molar ratio is 8 mol Al:3 mol Fe₃O₄. Calculate the moles of Al
Moles of Al = 6.34 × 8/3
Moles of Al = 6.34 × 2.667
Moles of Al = 16.9 mol Al
