hi, first pages are the completed first part, accordingly answer part 2 and 3. please answer each i posted two questions on this and got an empty answer. i dont have many questions left. thank you i will thumbs up!

up to here are answers to use

here starts what needs to be answered.

Part 1: Cltric Acid + Sodium Hydrogen Carbonate Part 2: Hydrochloric Acid + Magnesium Part 3: Hydrochloric Acid + Magnesium Oxide Part 1: Citric Acid + Sodium Hydrogen Carbonate Part 1: Citric Acid + Sodium Hydrogen Carbonate The strategy with this set of calculations is to determine the amount of heat transferred per one mole of the limiting reagent in the experiment. The limiting reagent in Part 1 is sodium hydrogen carbonate. To determine the amount of heat transferred in the reaction we use H=msT. Once this value has been calculated then the units are converted from Joules to kilojoules.
