Astudent in lab combined 41.514 g of 1.0 m hcl solution (d = 1.0 g/ml) with 51.158 g of 1.0 m naoh solution (d = 1.0 g/ml) in a coffee cup calorimeter and recorded the temperature data below. calculate the enthalpy change (∆ ° ) per mole of hcl. (assume the specific heat capacity of the solution is the same as water, 4.184 j/g‧k.) hcl(aq) + naoh(aq) → h2o(l) + nacl(aq)

the only liquid elements at standard temperature and pressure are bromine (br) and mercury (hg). although, elements caesium (cs), rubidium (rb), francium (fr) and gallium (ga) become liquid at or just above room temperature.

explanation:

b. accuracy of the data matters alot more than its number of digits, organization or amount of detail. quantitative observation is more accepted than the qualitative observation.
