Four beakers of equal size with equal volumes contain four different solutions of salt water as seen above. If beaker 1 has 55 g of salt dissolved in 500 mL, beaker 2 has a concentration of 0.21 g/mL, beaker 3 has 36 g of salt dissolved in 144 mL of water, and beaker 4 has a concentration of 0.23 g/mL, then which of the following lists the solutions in order from most concentrated to least concentrated? A)2, 4, 3, 1

B)3, 4, 2, 1

C)1, 2 4, 3

D)1, 2, 3, 4

b. acid is the correct answer @jayxboof all social media

acid : acids are those which accepts an electron-pairs.

base : bases are those which donates ab electron-pairs.

alkali : it is a base that dissolves in water. it is basically a base and the ph greater than 7.

hydroxide ion : it is a poly-atomic ion which is negatively charged.

the answer is b because, investigating whether another species of moth also drinks tears might be interesting, but it would not directly explain why this species of moth does.

to explain why this species of moth drinks tears, the scientist could ask: "what nutrients that moths need are in elephant tears? "

the scientist could experiment with moth repellent or oter ways to keep the moths away, but that would not answer his original question.

qualitative observation deals with data that can be observed with our senses: sight, smell, touch, taste, and hearing. they do not involve measurements or numbers. for instance, colors, shapes, and textures of objects are all qualitative observations.
