A substance decomposes with a rate constant of 9.05 x 10-45-1. How long does it take for 13.0% of the substance to decompose?

m=9

step-by-step explanation:

7m+8=71 subtract   8 from 71 which is 63 than divide it by 7m   equal 9.

                             

Ithink this is what you meant. the temperature at which a liquid begins to boil is called the boiling point. the boiling point of water is 212°f or 100°c.  and at that point will start to turn into steam (gas)

The teacher is mostly talking about the distillation of a mixture

The answer is 4 i don't know if its right let me see.
