Answer: The Anode reaction is 
Explanation:
Oxidation-reduction reaction or redox reaction is defined as the reaction in which oxidation and reduction reactions occur simultaneously.
Oxidation reaction is defined as the reaction in which a substance looses its electrons.Oxidation occurs at anode.
Anode :
Reduction reaction is defined as the reaction in which a substance gains electrons. Reduction occurs at cathode.
Cathode : 
If the total mass of the reactants is 49g then the mass of the products also equals 49g.
It is due to the law of conservation of mass.
Mass can neither be created nor be destroyed.
Im not that’s sure because it’s very confusing let me find out wait
The chemical reaction is the oxidation of calcium metal by molecular oxygen. During the reaction, calcium metal is oxidized, that is, loses electrons and oxygen is reduced, that is gains electrons.
During the reaction, the calcium atom donate two electrons in order to become stable and the oxygen atom accepts these two electrons. Therefore, during the reaction, EACH OXYGEN ATOM GAINS TWO ELECTRONS.
Answer:
This is all in the reading, and some is just common sense. The Sun seems to rise in the East and Set in the West, right? Have you never observed the moon and its movements, at least as they appear here on Earth?
Explanation:
It was in great part by watching the Sky that mankind learned when to plant crops, when harvest was coming; it will be a great thing for you to look at Nature and the Sky, and read the books!
