Four acids are analyzed and their ka values are determined. which of the following values represents the strongest acid?

Given four acids with different Ka's, the strongest acid will be the one with the greatest Ka. This can be verified by taking the -log(Ka). Larger Ka will result to less pH which means it becomes more acidic. Less Ka means it is relatively basic compared to others.

You need to divided twenty four by a dozen them by the temperature it is getting cook by

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.
