If 1.2 kilograms of rust form on a bridge in five days, what should be the rate of reaction in grams per hour? (Recall that a bar over the number means that zero is significant.)

100 (first zero has bar over it) g/hr

0.05 g/hr

0.010 g/hr

10 (zero has bar over it) g/hr

I believe the correct answer from the choices listed above is the last option. If 1.2 kilograms of rust form on a bridge in five days, the rate of reaction in grams per hour would be 10 (zero has bar over it) g/hr. Hope this answers the question. Have a nice day.
