Chapter 2, Problem 4RQ

Where within an atom are the three types of subatomic particles located?

What does the formula DPD = SF – TP mean?

What is polarity?

According to chemist John Dalton, if one mole of nitrogen is combined with three moles of hydrogen to form one mole of ammonia (knowing that nitrogen, with an atomic number of 7, has an atomic mass of 14, and hydrogen, with an atomic number of 1, has an atomic mass of 1), then this compound will have an atomic weight (or molecular mass) of: 14 grams per mole (14 daltons) 17 grams per mole (17 daltons) 20 grams per mole (20 daltons) 22 grams per mole (22 daltons)  43 grams per mole (43 daltons)

Arrange the elements Na, Si, and S in the order of(a) decreasing atomic radius.(h)increasing first ionization energy.

What are basic macromolecules?

What are Reversible Reactions?

In your own words define what is Dark matter?

In addition to solid, liquid, and gas, we also have plasma. Plasma, the "fourth state," is characterized by lack of shape, and it cannot be classified as gas, liquid, or solid. Examples of plasma are plasma ball and the contents of a fluorescent bulb. The fifth state has already been discovered by scientists. It is called Bose-Einstein Condensate (BEC), but in Grade 3, the focus of study is only on the three states of matter: solids, liquids, and gases. Let us have some exercises on grouping of matter.
