If the amount of energy required to break bonds in the reactants is more than the amount of energy released in forming bonds in the products, the chemical reaction is endothermic. (2 points) True

If 10.g of agno3 is available, what volume of 0.25 m agno3 can be prepared

Which statement best describes the flow of energy in this scenario

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.
