The kinetic theory states that potential energy in a gas is low but has high potential energy and they move around fast, Say in a solid it has more potential energy but less kinetic.
<u>Answer</u>:-
When the reaction takes place Ca is reduced or is an oxidizing agent.
Reaction:
Ca + 2Cl =CaCl2
Note: There is a +2 charge on Ca(Calcium) and -1 charge on each Cl-atom(Chlorine atom) hence the charges are cancelled. Therefore, the total charge on the whole compound is zero.
Explanation:-
• Reduction: gain of electron/electrons
gain of hydrogen
loss of oxygen
Oxidation: gain of oxygen
loss of hydrogen
loss of electron/electrons.
• Oxidizing agent/reduced
Reducing agent/oxidized
• The molecule that is oxidized loses an electron and the molecule that is reduced gains the electron that was lost by the oxidized molecule.
Your weight would be less but your mass would remain the same.
Answer:
D. Z, X, Y
Explanation:
Step 1: Z
Within the Sun two protons fuse together and when this proton-proton pair breaks apart one proton transform into neutron due to weak nuclear force. Along with transformation of neutron, a positron also formed and proton-neutron pair sometimes form deuterium.
Step 2: X
Collision of third proton takes place with deuterium and this collision results in formation of Helium-3 along with gamma rays. These gamma rays are also released as sunlight.
Step 3: Y
Collision of two Helium-3 nuclei takes place which results in creation of Helium-4.
