The vector sum of the external forces F on an object is equal to the mass m of that object multiplied by the acceleration vector a of the object: F = ma. Third law: When one body exerts a force on a second body, the second body simultaneously exerts a force equal in magnitude and opposite in direction on the first body.
Another way of stating âHessâs Lawâ is: If two chemical equations can algebraically be combined to give a third equation, the values of (H for the two equations can be combined in the same manner to give (H for the third equation.inally, to verify Hessâs Law, you will use the (Hâs you measured for the first two reactions to calculate (H for the third reaction. Compare it to what you measured for the third reaction by calculating the Percent Error.
