Mass of Oxygen required : 24 grams
<h3>Further explanation</h3>
Given
3 moles of H
1.5 moles of O
3 moles of H₂O
Required
Mass of O
Solution
Reaction
2H₂ + O₂ ⇒ 2H₂O
Mass of Oxygen for 1.5 moles of O :
= mol x Ar O
= 1.5 moles x 16 g/mol
= 24 grams
Answer:
50,000,000 Hz
Explanation:
<em>Rearrange the formula:</em>
wave speed = frequency × wavelength → frequency = wave speed ÷ wavelength
wave speed = 300,000,000m/s
wavelength = 6m
<em>Substitute in the values:</em>
frequency = 300,000,000 ÷ 6
frequency = 50,000,000 Hz
Hope this helps!
Answer
As temperature increases, the molecules of the gas have more kinetic energy. They strike the surface of the container with more force. If the container can expand, then the volume increases until the pressure returns to its original value.

Answer:
The correct answer is - nuclear fission.
Explanation:
In the given diagram, the reaction is a graphical representation of the nuclear fission of one nucleus of Uranium 235 into two nuclei of Kr with three neutrons that leads to a chain reaction and releases a huge amount of energy and grow out of control.
With every fission, there are two neutrons emitted which results in splitting more nucleus into two nuclei and keep on growing and never die out. The amount of energy also keeps on growing with an increase in the reactions and fission. This reaction is used to generate electricity and nuclear weapons.
