What is the final temperature of the solution formed when 1.52 g of NaOH is added to 35.5 g of water at 20.1 ∞C in a calorimeter?

NaOH (s) ---> Na +(aq) + OH –(aq) DH = -44.5 kJ/mol

in chemistry, a solution’s concentration is how much of a dissolvable substance, known as a solute, is mixed with another substance, called the solvent. the standard formula is c = m/v, where c is the concentration, m is the mass of the solute dissolved, and v is the total volume

the answer is   c.) 1575 j.

explanation:

your answer is a. the enthalpy of formation for a pure element in its standard state is always positive.

c-14 is carbon-14, or radiocarbon.   it is a radioactive isotope of carbon with an atomic nucleus containing 6 protons and 8 neutrons.
