B) NH3(aq) + HF(aq) → NHat(aq) + F-(aq)
C) NO2(aq) + Al(s) → NH3(g) + AlO2 (aq)
D) CH2(g) + 202(g) → 2H2O(g) + CO2(g)

What are fructose and glucose an example of?

When hydrochloric acid reacts with potassium hydroxide solution, the following reaction occurs. hcl (aq) + koh (aq) h2o (l) + kcl (aq) the reaction gives off heat energy, so it is an reaction.

Acalorimeter is to be calibrated: 51.203 g of water at 55.2 degree c is added to a calorimeter containing 49.783 g of water at 23.5c. after stirring and waiting for the system to equilibrate, the final temperature reached is 37.6 degree c. specific heat capacity of water (s = 4.18 j/g∙degree c). calculate the calorimeter constant. (smδt)warm water = -[(smδt)cold water + (calorimeterδtcold water)]
