Answer:
850g/min
Explanation:
The reaction expression is given as:
P₄ + 5O₂ → P₄O₁₀
Given that:
Number of moles of product = 1.5moles
Time = 30s = 0.5min
Unknown:
The rate of the reaction = ?
Solution:
Convert the moles given to mass of the product.
So;
Mass of product = number of moles x molar mass
Molar mass of P₄O₁₀ = 4(31) + 10(16) = 284g/mol
Mass of product = 1.5moles x 284g/mol = 426g
So;
Reaction rate =
=
= 850g/min
The atomic symbol for an isotope with 4 protons and 5 neutrons is Beryllium ( Be)................
The answer is 60 minutes to complete 50% of reaction.
If you are talking about bonds they are influenced by electronegativity and how many valence electrons they have.
Answer:
56.97kJ
Explanation:
1 mole of N2 reacts with 73.8kJ
0.772 mole of N2 reacts with xkJ
cross multiply
x= 0.772×73.8
=56.97kJ
