I not understand your questions
The volume of the sample after the reaction : V₂=5.484 L
<h3>Further explanation</h3>
Given
Reaction
2HBr(g) + Cl2(g) => 2HCl (g)+Br2(g)
0.1100 mol of HBr(g)
5x10⁻² mol of Cl2(g)
Required
The volume of the sample after reaction
Solution
Find limiting reactant :
0.11/2 : 0.05/1 = 0.055 : 0.05
Limiting reactant : Cl₂
mol Products based on mol Cl₂
mol products = mol HCl + mol Br₂
mol products = 2/1x0.05 + 1/1x0.05
mol products = 3 x 0.05 = 0.15
mol reactants = 0.11 + 0.05 = 0.16
<em>From Avogadro's law, </em>
In the same T, P, and V, the gas contains the same number of molecules
So the ratio of gas volume will be equal to the ratio of gas moles
V₁/n₁=V₂/n₂
1 = reactants, 2 = products
Input the value :
5.85/0.16=V₂/0.15
V₂=5.484 L
Answer: 12033 kJ of heat produced per kg of 
formed during the combustion of benzene
Explanation:
The balanced chemical equation for combustion of benzene is :
= -6278 kJ
Exothermic reactions are defined as the reactions in which energy of the product is lesser than the energy of the reactants. The total energy is released in the form of heat and 
for the reaction comes out to be negative.
(1kg=1000g)
According to stoichiometry :
12 moles of on combustion produce heat = 6278 kJ
Thus 23 mole of on combustion produce heat =
Thus 12033 kJ of heat produced per kg of formed during the combustion of benzene

number 2 WEATHER MAPS indicate atmospheric conditions above a large portion of the Earth’s surface. Meteorologists use weather maps to forecast the weather. A HYGROMETER measures the water vapor content of air or humidity. A WEATHER BALLOON measures weather conditions higher up in the atmosphere.
number 3 A climate is an average weather in a given area over a period of time. The weather, on the other hand, can change drastically in a matter of hours. Changing the world takes thousands of years. It is, however, complex and has been growing at an alarming rate in recent years.
Weather refers to how the environment behaves, mostly in terms of its impacts on life and human habits. Temperature, humidity, precipitation, brightness, cloudiness, visibility, wind, and atmospheric pressure all are factors that influence the weather on a daily basis.
