Tori wants to increase the temperature of 500 grams of water from 20 c to 100 c if the specific heat of water is 4.18 j g c how much heat is needed

What is the relation between concentration of reactants and the rate of chemical reaction?

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.
