To perform nuclear fusion reactions, the following requirements must be present: Get a very high temperature to separate the electron from the nucleus, approaching this another beating electrostatic repulsion forces. The gaseous mass consisting in the electrons and free atoms is called highly ionised plasma.
So, it’s chemical plasma.
Hope this helps:)
Keeping your arm straight in front of you, you rotate 90° to your left, and see the left side of the circle lit while the right side is dark. Half the ball is still lit up, but you can see only part of the lit area. As you continue to rotate, you see a different amount of the ball.
4 moles of hydrogen = 4 * 1.008 = 4.032 grams
1 mole of helium = 4.003 grams
Difference is 4.032 - 4.003
= 0.029 g
The answer is C. 146g because you add all of the masses of the individual elements and then mulyiply by 1.72 to get your answer.
