Carey burns 1.28 grams of chips in a laboratory experiment. He notices the temperature of 50 grams of water in a can above the burning go from 31.5 °C to 63 °C. How many calories did his sample release?

Temperature is _related to the average kinetic energy of a gas. inversely directly not disproportionally

Which statement can best be concluded from the ideal gas law?

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.
