Answer : The ratio of hydrogen and oxygen in water is, (2:1)
Explanation :
As we know that the chemical formula of water is, .
In , there are 2 atoms of hydrogen and 1 atom of oxygen.
As we are given that the volume of water is, 2 L. So, there is no matter what is the volume of water that means there is no role of volume of water.
The ratio of hydrogen and oxygen in water is, (2:1)
Thus, in 2 L volume of water, the ratio of hydrogen and oxygen in water is also same that is, (2:1)
Explanation :
The balanced chemical reaction is,
The expression for the rates of consumption of the reactants are:
The rate of consumption of =
The rate of consumption of =
The rate of consumption of =
The expression for the rates of formation of the products are:
The rate of consumption of =
The rate of consumption of =
Answer:
66.67%
Explanation:
From the given information:
mass of cyclohexane = 2.9949 grams
density of cyclohexane = 0.779 g/mL
Recall that:
Density = mass/volume
∴
Volume = mass/density
So, the volume of cyclohexane = 2.9949 g/ 0.779 g/mL
= 3.8445 mL
Also,
mass of propylbenzene = 1.6575 grams
density of propylbenzene = 0.862 g/mL
Volume of propylbenzene = 1.6575 g/ 0.862 g/mL
= 1.9229 mL
The volume % composition of cyclohexane from the mixture is:
= 66.67%
