Please answer ans................

Answer 1

Answer:X = Y+Z

Explanation:

See C + O₂→CO₂

So we just need to add the rections in the bottom to get this.

A trick would be to reduce the subtract when the compunds are on the oppositte side of the arrow and add whatever is on the same side of the answer.

Ex: You will see that CO will get cancelled out when you add the 2nd and third reaction and you will add up oxygen on the rectant side to one.
