Answer:
see explanation
Explanation:
To determine limiting reactant divide mole quantities of reactants by the respective coefficient in the balanced equation. The smaller value is the limiting reactant.
P₄ + 5O₂ => 2P₂O₅
12/1 = 12 15/5 = 3
O₂ is the limiting reactant. P₄ will be in excess when rxn stops.
To find the IUPAC name for compounds, you must memorize prefixes and suffixes and other terms in determining or naming a compound. The IUPAC name for compound ZnO is Oxozinc or Zinc Oxide. I hope this helps you on your assignment.
Answer: 50 grams
Explanation: The water is still only going to be 50 grams. Although it’s in a different state, it didn’t gain or lose any water while being frozen.
Answer:

Explanation:
First, we will calculate the molar mass of 
as follows.
Molar mass of = 
= 78 g/mol
So, when 2 mol of 
burns, then heat produced = 6542 KJ
Hence, this means that 2 molecules of 
are equal to 
of burns, heat produced = 6542 KJ
Therefore, heat produced by burning 5.5 g of =
= 228.97 kJ
= 228970 J (as 1 kJ = 1000 J)
It if given that for water, m = 5691 g
And, we know that specific heat capacity of water is 4.186 
.
As, Q = 
228970 J = 
Thus, we can conclude that the final temperature of the water is 
.
