Asample of chemical x is found to contain 5.0 grams of oxygen, 10.0 grams of carbon, and 20.0 grams of nitrogen. the law of definite proportion would predict that a 61 gram sample of chemical x should contain how many grams of carbon?

18g C

Explanation:

A sample of chemical X is found to contain 5.0 grams of oxygen, 10.0 grams of carbon, and 20.0 grams of nitrogen. The mass of that sample is:

5.0 g + 10.0 g + 20.0 g = 35.0 g

The ratio mC/mX is:

According to the law of definite proportion, this ratio is constant for the same chemical. For a sample of 61 g of X,

the cold front replaces the warmer air at the ground level changing the wind to be breezy and denser.there is also an immediate drop in the temperature.

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.
