<u>Given:</u>
Mass of asteroid, M1 = 5.00*10¹² kg
Velocity of asteroid V1 = 15.0 km/s
Mass of moon, M2 = 7.36*10²² kg
<u>To determine:</u>
The recoil velocity of moon, V2
<u>Explanation:</u>
Since the collision is perfectly inelastic, momentum is conserved. therefore,
M1 * V1 = M2* V2
V2 = M1*V1/M2 = 5.00*10¹² *15.0 /7.36*10²² = 1.02*10⁻⁹ km/s
Nitrogen combine with hydrogen to produce ammonia
at a
ratio:

Assuming that the reaction has indeed proceeded to completion- with all nitrogen used up as the question has indicated.
of hydrogen gas would have been consumed while
of ammonia would have been produced. The final mixture would therefore contain
Apply the ideal gas law to find the total pressure inside the container and the respective partial pressure of hydrogen and ammonia:
Answer:
Together, the number of protons and the number of neutrons determine an element's mass number: mass number = protons + neutrons. If you want to calculate how many neutrons an atom has, you can simply subtract the number of protons, or atomic number, from the mass number.
