Please help! Thanks! For an experiment, you have a calorimeter with 350 g of water at 24°C. 175 g of crystalline ammonium nitrate from a cold pack is placed into the calorimeter. When the ammonium nitrate finishes dissolving in the water, the temperature of the water inside the calorimeter is 5.5°C. The total mass of the solution is 525 g and the specific heat of the solution is 4.18 J/g °C (the same as water). What is the enthalpy of dissolving (ΔHdissolving) of in J/g ammonium nitrate? Work must be shown in order to earn credit. q = m x C x ΔT

The first-order rate constant for the gas phase decomposition of dimethyl ether is 3.2 x 10-4s-1at 450 °C. The reaction is carried out in a constant volume container. Initially only the reactant, dimethyl ether, is present and the pressure is 0.312 a..
Blood alcohol content (BAC) is often reported in weight-volume percent (w/v%). For example, a BAC of 0.08% corresponds to 0.08 g CH3CH2OH per 100 mL of blood. In Ontario, and the rest of Canada, the maximum legal BAC for fully licensed drivers is ..
