But my teacher's checker says it's not balanced.\n\nMs. Tanaka's balancing steps:\n1. Balance C first, then H.\n2. Balance O LAST, because O2 is by itself.\n3. Count every atom on each side at the end.\n4. \"Never change the little numbers (subscripts). Only change the big numbers in front.\"\n\nAnswer key is in the back of the book but I don't want to look.\n\nQuiz Thursday on balancing + reaction types.","rules":[{"type":"numberedItems","count":3},{"type":"maxWords","max":70},{"type":"plainText"}],"mistakes":[{"title":"Asking it to balance","why":"The AI's default is to hand you the balanced equation.","fix":"Say: \"Don't balance it.
