At the beginning of an experiment, a scientist has 308 grams of radioactive goo. After 210 minutes, her sample has decayed to 4.8125 grams. What is the half-life of the goo in minutes?

Find a formula for G(t), the amount of goo remaining at time t.

How many grams of goo will remain after 71 minutes?

Harvey kept a balloon with a volume of 348 milliliters at 25.0˚c inside a freezer for a night.  when he took it out, its new volume was 322 milliliters, but its pressure was the same.  if the final temperature of the balloon is the same as the freezer’s, what is the temperature of the freezer? the temperature of the freezer is  kelvins.

Indicate whether the specified alkyl halides will form primarily substitution products, only elimination products, both substitution and elimination products, or no products when they react with sodium methoxide. 1-bromobutane 1-bromo-2-methylpropane 2-bromobutane 2-bromo-2-methylpropane
