Please help me :(

Remember:
to balance equations in chemistry, you have to count the amount of atoms there are in a chemical eg:
the number of atoms in H20 are:
2 atoms of hydrogen
1 atom of oxygen (when there are no numbers by the letter it means that theres only 1 atom of it!)
The number next to a letter means the number of atoms thta it is made up of and atoms are the things it is made up of eg chocolate the ingredients are cocoa, milk and sugar ect so just like that CO2, H20 an ALL types of chemicals are made up of atoms. BUT WE WANT TO KNOW HOW MANY ATOMS- so u need to list these for all the 4 chemicals in the equation.
Im telling u this so that u can list out all of the atoms in each chemical (I will do the first two)
CH2=
1 atom of Carbon
2 atoms of hydrogen
O2=
2 atoms of oxygen
once u have listed out all the atoms from EACH of the chemicals in ur question (CH2, 02, CO2 and H20) categorise them like this
CH2
Carbon=........ Atoms
Hydrogen= .......Atoms
(Make sure the table is like vertical like lemme show u as an example. ATTACHED IS AN EXAMPLE OF WHAT UR WORK SHOULD BE SET OUT AS)
When you see the addition sign it means that elements like oxygen and hydrogen etc..basically add them up like CO2 + H20 theres oxygen in both so add up the atoms of oxygen FOR JUST CO2 AND H20 like if there was one atom of oxygen in CO2 and 2 in h20 add them up and it makes three (1+2=3). 1 oygen atom from CO2 plus 2 oxygen atoms in H20 that makes 3 atoms for both the chemiclas together (THIS WAS JUST AN EXMAPLE THERE ARENT ACTUALLY 2 ATOMS IN H20 OR 1 ATOM IN C02)
Look at the similarities OF ATOM NUMBERS like if CH2 has one atom of Carbon, CO2 ALSO has one atom of carbon which is fine BUT when it comes to differences u need to cross those out and PUT THAT NUMBER on both sides like if O2 has 2 atoms of oxygen and h20 has 1 that means that they need to be balanced like they either both need to be 1 atom or 2 atoms so for that u need to look attachment sorry u just need to cross them out and make them the same
make sure to write about what atoms are, to list out atoms for each chemical, compare the chemicals in both word chemicals and make them even!

Explanation:
Oxidizing agents are defined as the agents which oxidize other substance and itself gets reduced. These agents undergoes reduction reactions.
Reducing agents are defined as the agents which reduces the other substance and itself gets oxidized. These agents undergoes reduction reactions.
When oxidizing agent-A get reduced it changes green to colorless.
When oxidizing agent-B get reduced it changes yellow to colorless.
When oxidizing agent-C get reduced it changes red to colorless.
1) When we added solution C that oxidizing agent-C in solution containing ions changes from red to yellow:
So, in this C is oxidizing ion into B which yellow in color.
C is reduced and ions is oxidized.
Here, are oxidized by C which means that C a better oxidizing agent than B.
2) When a solution of C is mixed with one containing A- ions, the color remains red.
no reaction
As we had observed that no color change was seen on adding substance C to the solution with ions which indicates that C was unable to oxidize
ions. Hence, not a better oxidizing agent than A
