answer:
D.
explanation:
as days years months go by more and more new elements that are chemically made or are natural are added even though the ones at school have been updated for such a long period of time
Physical property includes color, taste, or feel of the object. answer us A.)
Answer:
To answer the question, we correctly fill the attached screenshot as follows;
- 3H₂ + N₂ → 2NH₃
- The molar mass of H₂ = 2 g/mol

The molar mass of N₂ = 28 g/mol

A. Therefore, the excess reactant is hydrogen gas H₂ because it makes the most amount of ammonia, NH₃ (33.
moles of NH₃)
B. The limiting reactant in nitrogen, N₂, because it is the reactant that makes the least amount of the ammonia, NH₃ (approximately 7.143 mol NH₃)
C. The theoretical yield of ammonia, is the maximum amount of ammonium that can be produced from the reaction between the 100 g of hydrogen gas, H₂, and 100 g of nitrogen gas, N₂ which is given by the amount of ammonia produced by the limiting reactant which is approximately 7.143 mole of NH₃
Explanation:
The number of moles of Co that would be required to react with 6.14 moles of P4 would be 36.84 moles
<h3>Stoichiometric calculations</h3>
From the equation of the reaction:
6Co + P4 → 2Co3P2
For every 1 mole of P4, 6 moles of Co is required for complete reaction.
Thus, the mole of Co that would be needed for 6.14 moles of P4 would be:
6 x 6.14 = 36.84 moles
