Answer:
The answer to your question is 1.36 moles of P₂O₅
Explanation:
Data
moles of P₂O₅ = ?
moles of O₂ = 3.4 moles
Balanced chemical reaction
4P + 5O₂ ⇒ 2P₂O₅
To solve this problem use proportions and cross multiplication. Consider the coefficients of the molecules of the balanced equation.
5 moles of O₂ --------------- 2 moles of P₂O₅
3.4 moles of O₂ ------------ x
x = (3.4 x 2) / 5
-Simplification
x = 6.8 / 5
-Result
x = 1.36 moles of P₂O₅
evaporation systems allow for an endless source of water. you can grab cups of water straight from the sea or even a lake. the use of evaporation allows for you to drink water thats even healthier than getting it from a cloud and it will leave all of the bad parts that used to be in the water in the first container you pour into. this system is most useful in hot climates such as places near the equator.

Answer:
7.22 L
Explanation:
From the question,
Applying Charles law,
V₁/T₁ = V₂/T₂...................... Equation 1
Where V₁ = Initial volume of gas, V₂ = Final volume of gas, T₁ = Initial Temperature of gas in Kelvin, T₂ = Final Temperature of gas in Kelvin
Make V₂ the subject of the equation
V₂ = (V₁×T₂)/T₁................. Equation 2
Given: V₁ = 5.00 L, T₁ = 20 °C = (20+273) K = 293 K, T₂ = 150 °C = (150+273) K = 423 K
Substitute these value into equation 2
V₂ = (5.00×423)/293
V₂ = 7.22 L
