Which ones of they statements our true? And which ones are false?

Question

I. Coefficients can be fractions.
II. Subscripts can be fractions.
III. Coefficients represent the relative masses of the reactants and/or products.
IV. Changing the subscripts to balance an equation can only be done once.
V. Atoms are conserved when balancing chemical equations.

Answer 1

I don't like T/F questions anytime but these are poor.
1. May be T or F depending upon the circumstances.
2. They CAN be but fractional subscript are not allowed.
3. no
4. May not be done even once.
5. yes.

In the future, you should tell us if you think the statement is T or F AND WHY YOU THINK THAT WAY. Remember you can guess and get half of them right if you answer enough T/F questions.
