1. calculate the molar enthalpy of solidification (δhsolidification) when 10.00kj of energy are lost as 30.00g of water are frozen at 0ºc. remember that this value will be negative, because energy is lost when water freezes. (hint: start by finding out how many moles of water that are freezing)

The snow gains heat to melt (endothermic), then the water releases heat to freeze (exothermic). ... Beaker becomes hot because the reaction is pushing heat out from itself onto solidification (ΔHsolidification) when 10.00kJ of energy are lost as 30.00g of water.

Explanation:

14 days is the half-life of phosphorus-32

they it depends on if one believes about radioactivity, they make a geiger counter beep but maybe it was going to beep anyway electronics do wierd things all the time or it was programmed to beep near certain metals.
