Gin an experiment a student mixes a 50.0 ml sample of 0.100 m agno3 (aq) with a 50.0 ml sample of 0.100 m nacl(aq) at 20.0°c in a coffee-cup calorimeter. which of the following is the enthalpy change of the precipitation reaction represented above if the final temperature of the mixture is 21.0°c? (assume that the total mass of the mixture is 100. g

Which units can be used to measure length or distance? check all that apply. gram meter kilometer liter inch
