A solution was prepared by dissolving 1210 mg of K3Fe(CN)6 (329.2 g/mol) in sufficient water to give 775 mL. Calculate (a) the molar analytical concentration of K3Fe(CN)6. (b) the molar concentration of K1. (c) the molar concentration of Fe(CN)6 32. (d) the weight/volume percentage of K3Fe(CN)6. (e) the number of millimoles of K1 in 50.0 mL of this solution. (f ) ppm Fe(CN)6 32. (g) pK for the solution. (h) pFe(CN)6 for the solution

chemical energy is stored in the chemical bonds of atoms and molecules. it can only be seen when it is released in a chemical reaction. when chemical energy is released, the substance from which the energy came is often changed into an entirely different substance.

this chemical reaction releases energy in the form of light and heat. chemical energy is the potential energy stored in the arrangement of atoms within molecules. breaking chemical bonds requires energy, while forming new chemical bonds releases energy.

the atp molecule can store energy in the form of a high energy phosphate bond joining the terminal phosphate group to the rest of the molecule. in this form,energy can be stored at one location, then moved from one part of the cell to another, where it can be released to drive other biochemical reactions.

metric time was an attempt to create a standard unit of time based off of 10, but it never took off an is not included in the metric system (si)
