In the Equilibrium and Concentration Gizmo, you found that reversible reactions eventually result in chemical equilibrium. Chemical equilibrium is reached when the rates of the forward and reverse reactions are the same. The constant Kc describes the ratio of products to reactants at equilibrium. A similar equilibrium can be calculated based on partial pressure. Question: How can partial pressure be used to measure equilibrium

Mass is the amount of matter in an object.  weight is the measurement of the pull of gravity on an object.  say for example, you travel to the moon which has a different gravitational field compared to the gravitational field of earth. (gravitational fields: earth = 1, moon = 0.165)  now when you are on the moon, the pull of gravity on you is different than on the earth. and as weight is the measurement of the pull of gravity on an object, that means yes, your weight can and will change on the moon.  however, on the moon, on earth or even on jupiter, the amount of mass inside of you remains the same. meaning your physical mass remains constant.  in conclusion it is possible for your weight to change as your mass remains constant.
