Answer:
Wavelength is 10m
Explanation:
To solve this problem, we use the formula for wavelength
Wavelength = wave velocity / frequency
Wavelength = 50m/s / 5Hz
= 10m
A) It decreases because the distance between the nucleus and outermost shell increases
2 atoms will bond with calcium to form Calcium Fluoride
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
