Answer:
0.89 atm is the pressure of the hydrogen gas
Explanation:
We can use the molar fractions to solve this
Sum of molar fractions (hydrogen + water vapor) = 1
Molar fraction = Pressure gas / Total pressure
Molar fraction water vapor = 0.13 atm/1.02 atm = 0.127
1 - 0.127 = 0.873 (Molar fraction H2)
0.873 = Pressure H2 / Total pressure
0.873 = Pressure H2 / 1.02 atm
0.873 . 1.02atm = 0.89 atm

Answer:
CaC₂(s) + 2H₂O(l) --> C₂H₂(g) + Ca(OH)₂(aq)
Explanation:
We are given;
The unbalanced equation;
CaC₂(s) + 2H₂O(l) --> C₂H₂(g) + Ca(OH)₂(aq)
We are required to balance the equation;
- We need to know that balancing of chemical equations involves putting the appropriate coefficients on reactants and products to ensure equal number of atoms of each element on both sides of the equation.
- Balancing of chemical equations is a try and error method of making sure that the law of conversation of mass in chemical equations is obeyed.
- In our case, the appropriate coefficients will be, 1, 2, 1, 1
Therefore;
The balanced equation will be;
CaC₂(s) + 2H₂O(l) --> C₂H₂(g) + Ca(OH)₂(aq)
Hello!
Yes, a cubic meter is different from a cubic centimeter.
A centimeter consists of 10 millimeters, and a meter consists of 100 centimeters (1,000 millimeters). A cubic meter is fairly larger than a cubic centimeter.
I hope this helps you! Have a great day!
