100.0 mL of 0.100 M sodium sulfide is mixed with 100.0 mL of 0.100 M chromium (III) nitrate. Calculate the mass of solid that forms and the concentration of the remaining species in solution: assume complete precipitation.
A 100.0 mL sample of 0.300 M NaOH is mixed with a 100.0 mL sample of 0.300 M HCl in a calorimeter. Both solutions were initially at 35.00°C and the final temperature of the resulting solution was recorded as 37.00°C. Write a balanced chemical reaction for the neutralization reaction between aqueous NaOH and HCl, determine the number of moles of water formed in this reaction, and calculate the overall heat change of the solution. Assume 1) that no heat is...

If you mix 100.0 mL of 0.125 M HCl (strong acid) with 50.0 mL of 0.175 M NaOH (strong base) what will be the pH of the resulting solution? Have you reached the endpoint of the reaction (circle your answer)? YES NO Explain your answer:
HCl(aq) + NaOH(aq) → NaCl(aq) + H2O(1) 100.0 mL of 0.500 M HCl is mixed with 300.0 mL of 0.100 M NaOH in a coffee cup calorimeter. Assuming the temperature of the solution was initially 25.0 °C, and the final temperature of the solution was 26.7 °C, calculate the enthalpy of this reaction per mole of HCl. Assume the density of the water and acid and base solutions are all 1.00 g/mL.
