When citric acid and baking soda were dissolved in 150.0 grams water, the reaction absorbed 2,550 J of energy. If the water was initially 35.0˚C what would the final temperature of the water be? Hint: Solve for the change in temperature first. Water has a specific heat of 4.18 J/g˚C.

Which of the following is a compound? a. carbon b. oxygen c. hydrogen d. water

The content of manganese (mn) in steel was determined spectrophotometrically and with the use of the standard addition method. an unknown sample of mn from a digested steel sample gave an absorbance of 0.185 when analyzed spectrophotometrically. when 5.00 ml of solution containing 95.5 ppm mn was added to 50.0 ml of the unknown steel solution (digested sample), the absorbance was 0.248. calculate the concentration, in parts-per-million (ppm), of mn in the digested steel sample solution.
