11 dilute hydrochloric acid is gradually added to a solution that is buffered at ph 4.76. how will the ph of the solution be affected?
the ph will initially remain close to 4.76, then increase quickly when the buffering capacity is exceeded.
the ph will gradually approach 4.76
the ph will initially remain close to 4.76, then decrease quickly when the buffering capacity is exceeded
ant
the ph will remain close to 4.76 indefinitely

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.
