<u>Answer:</u> The limiting reagent in the reaction is bromine.
<u>Explanation:</u>
Limiting reagent is defined as the reagent which is completely consumed in the reaction and limits the formation of the product.
Excess reagent is defined as the reagent which is left behind after the completion of the reaction.
Given values:
Moles of iron = 10.0 moles
Moles of bromine = 12.0 moles
The chemical equation for the reaction of iron and bromine follows:
By the stoichiometry of the reaction:
If 3 moles of bromine reacts with 2 moles of iron
So, 12.0 moles of bromine will react with = 
of iron
As the given amount of iron is more than the required amount. Thus, it is present in excess and is considered as an excess reagent.
Hence, bromine is considered a limiting reagent because it limits the formation of the product.
Thus, the limiting reagent in the reaction is bromine.
Answer:
Balanced chemical equation:
NO₂ + NO₃ → N₂O₅
Explanation:
Chemical equation:
NO₂ + NO₃ → N₂O₅
Balanced chemical equation:
NO₂ + NO₃ → N₂O₅
Nitrogen trioxide gas combine with nitrogen dioxide gas and form nitrogen pentoxide.
This is the simple synthesis reaction in which two substance combine to form a new substance.
Synthesis reaction:
It is the reaction in which two or more simple substance react to give one or more complex product.
General chemical equation:
A + B → AB
A and B are reactants that combine to form AB product.
Answer:
The new volume is 63583 L
Explanation:
Step 1: Data given
The initial volume of the balloon = 5.37 * 10^4 L
The initial pressure = 0.995 atm
The initial temperature = 32.0 °C = 305.15 K
The pressure decreased to 0.720 atm
The temperature decreased to -11.7 °C = 261.45 K
Step 2: Calculate the new volume
P1*V1 / T1 = P2*V2/T2
⇒with P1 = the initial pressure = 0.995 atm
⇒with V1 = the initial volume = 5.37 *10^4 L
⇒with T1 = the initial temperature = 305.15 K
⇒with P2 = the decreased pressure = 0.720 atm
⇒with V2 = the new volume = TO BE DETERMINED
⇒with T2 = the decreased temperature : 261.45 K
(0.995 * 5.37*10^4)/305.15 = (0.720 * V2) / 261.45
V2 = 63583 L
The new volume is 63583 L
Answer: The partial pressure of oxygen in the mixture is 321 mm Hg
Explanation:
According to Dalton's law, the total pressure is the sum of individual pressures.
Given : 
= total pressure of gases = 752 mm Hg
= partial pressure of Helium = 234 mm Hg
= partial pressure of nitrogen = 197 mm Hg
= partial pressure of oxygen = ?
Putting in the values we get:
The partial pressure of oxygen in the mixture is 321 mm Hg
