2A(g) + B(g) AzB(g) The above reaction was conducted in a rigid container by combining 0.50 atm A and 0.50 atm. The container was maintained at high temperature. As the reaction progresses, which of the following statements is correct regarding the total pressure in the flask? Select one:
O a. The pressure willincrease because the total mass in the container increases as reactions proceed.
O b. The pressure will decrease because the total number of moles declines as reactants are converted to product.
O c. The pressure will increase because the moles of A, B are produced as the reaction progresses.
O d. The pressure will decrease because energy is being used in the reaction. Clear my choice

Because it was a dramatically big guy

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.
