Methanol and methylamine are both combustible fuels. How many grams of methylamine must be combusted to raise the temperature of 397 g of water from 20.0°C to 43.0°C? Assume that the transfer of heat from the flame to the water is 100% efficient. g

Aphysical change is one that you can put in and remove like a ham sandwich. the stuff you put in there can be changem its not permanet. a chemical change is on that can't be change thats permanet. like when you make a cake and bake it. you can't get those ingredients back.

Hello! data: p (pressure) = 1.25 atmv (volume) = ? (in l)t (temperature) = 298 kn (number of mols) = 0.900 molesr (gas constant) = 0.082 (atm*l/mol*k)apply the data to the clapeyron equation (ideal gas equation), see: i hope this . =)
