I think the correct answer from the choices listed above is option C. A correct comparison between the modern quantum model and John Dalton’s model of the atom is the modern model recognizes particles in the atom, whereas Dalton’s model does not. Hope this answers the question.

Answer from: freshysans4

The correct option is (c).

Explanation:

In quantum model of atom , atom consist of subatomic particles: protons , electrons and neutrons. Where electrons are found in orbitals which are contained by orbits or energy levels around the nucleus. Protons and neutrons are concentrated in nucleus of the atom where whole mass of atom resides. This model also explained the probability of finding the electrons with the help of emission spectra.

In Dalton's model of the atom, atom was considered as the smallest indivisible unit of matter.

So, the correct answer is (c).

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.

Answer from: Quest

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.
