If the chemical formula of C is A2B5, the chemical equation of the reaction is () A. 2AB2+B2═2CB. 3AB2+B2═2CC. 4AB2+B2═2CD. AB2+4B2═2C

A. According to the number of a and B atoms before and after the reaction remains unchanged, we can know that: before the reaction, the number of a atoms is 2, the number of B atoms is 6, after the reaction, 2C molecules contain 4 a atoms and 10 b atoms, so it is not in line with the problem, wrong; B, according to the number of a and B atoms before and after the reaction remains unchanged, we can know that: the reaction
