Answer:
So combining blue with yellow light is like combining blue light with red and green light. The result of combining these three primary colors of light is to produce white light.
Explanation:
Let the mass of the solute be x
So, the equation would be
x/2.5+x ×100 = 23.22
x/2.5+x = 23.22/100
100x = 58.05 + 23.22x
100x - 23.22x = 58.05
76.78x = 58.05
x =0.756 ≈ 0.76 litres

Explanation:
The given data is as follows.
T = 
= (11 + 273) K = 284 K, V = 45.0 L
m = 35 g
As molar mass of chlorine pentafluoride is 130.445 g/mol. Hence, number of moles of chlorine pentafluoride are as follows.
No. of moles = 
= 
= 0.268 mol
Now, using the ideal gas equation we will find the pressure as follows.
PV = nRT
P = 0.139 atm
Thus, we can conclude that pressure of chlorine pentafluoride gas in the given reaction vessel after the reaction is 0.139 atm.
using the equation of formation of water:
H2+O2---->H2O
Balancing the equation,
2H2+O2---->2H2O
So now use the ratio from the balance equation, we know that 2 mol of H2 are producing 2 mol of H2O so the ratio will be 1:1.
So as 2 mol of H2O are produced by 2 mol of H2.
That implies 1 mol of H2O are produced by 1 mol of H2.
That is 0.253 mol of H2O are produced by 0.253 mol of H2.
