Answer:
Equilibrium constant Kc for the reaction will be 1.722
Explanation:
O2(g)+NO(g)→CO(g)+ NO2(g)

0.88x 3.9-x x x
GIVEN:
0.88X-X= 0.11
⇒ X=0.77
CO2(g)+NO(g) → CO(g) + NO2(g)

Answer:
<h2>A.EXACTLY CROSSING EARTH'S ORBIT OF THE SUN</h2>
Answer:
Answer: The correct answer is Option B.
Explanation:
To calculate the number of moles, we use the equation:
\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}Number of moles=Molar massGiven mass ....(1)
For N_2N2 :
Given mass of nitrogen gas = 10 g
Molar mass of nitrogen gas = 28 g/mol
Putting values in above equation, we get:
\text{Moles of iron oxide}=\frac{10g}{28g/mol}=0.357molMoles of iron oxide=28g/mol10g=0.357mol
The given chemical reaction follows:
N_2+O_2\rightarrow 2NON2+O2→2NO
As, oxygen gas is present in excess. Thus, it is considered as an excess reagent and nitrogen is considered as a limiting reagent because it limits the formation of products.
By Stoichiometry of the reaction:
Answer:
The final temperature of the mixture is 21.4°C
Explanation:
Specific heat capacity of water = 1 cal/g°c
Heat loss by water = 77.1 g X 1 cal/g°c X 50.9°c = 3924.39 Cal
Latent heat of fusion of ice = 79.7 g⁻¹
Heat required to melt ice at 0°c= 22.5 g X 79.7 g⁻¹ = 1793.25 Cal
Heat gained by ice from water at a higher temperature, T°c = 22.5 X 1 X T
= 22.5T
Also heat lost by water = 77.1 X 1 X (50.9-T)cal
By calorimetric principle
Heat lost by a hot body = heat gained by a cold body
77.1 X 1 X (50.9-T) = 22.5T + 1793.25
3924.39 -77.1T = 22.5T + 1793.25
99.6T = 3924.39 - 1793.25
T = 2131.14/99.6
T = 21.4°C
Therefore, the final temperature of the mixture is 21.4°C
