Akia is balancing the equation na + h2o naoh + h2. he tries to find the coefficients that will balance the equation.
how could he find the correct coefficients?
a: by counting up each individual atom and make sure the atom numbers are the same in the reactants and the products
b: by counting up the total atoms and make sure the number of atoms in the reactants is the same as the number of atoms in the products
c: by counting up the total mass of each compound and make sure the reactants are more than the products
d: by counting up the mass of each atom and make sure the reactants are more than the products

As you are trying to move a heavy box of mass m, you realize that it is too heavy for you to lift by yourself. there is no one around to , so you attach an ideal pulley to the box and a massless rope to the ceiling, which you wrap around the pulley. you pull up on the rope to lift the box. use g for the magnitude of the acceleration due to gravity and neglect friction forces. once you have pulled hard enough to start the box moving upward, what is the magnitude f of the upward force you must apply to the rope to start raising the box with constant velocity? express the magnitude of the force in terms of m, the mass of the box.
