If the population of the United States increased to 3500million and the number of representatives remained 435, how many Americans, on average, would each representative serve?

A proposed amendment to the U.S. Constitution has passed both the House and the Senate with more than the required two-thirds super majority. Each state holds a vote on the amendment, and it receives a majority vote in all but 14 of the 50 states. Is the Constitution amended? Explain why

Four elements are identified only by atomic number: P: 3 Q: 11 R: 17 S: 18 Which comparison is most likely true?

As you move from left to right across a period in the periodic table, atomic radius generally:

A neutral atom: Contains 20 neutrons. Has 18 electrons. Belongs to the noble gases. Has a lower mass number than another isotope of the same element. Which statement must be true?

A laboratory bench has a length of {L} m. Convert this length to centimeters.  Enter your answer as a number only.

A sealed container recovered from a laboratory contains a colorless gas. Scientists make the following observations: The gas is a pure substance. Spectroscopic analysis shows a single set of emission lines. Every atom in the sample contains 18 protons. Approximately 60% of the atoms contain 22 neutrons, while 40% contain 20 neutrons. The gas is extremely unreactive under normal conditions. Repeated mass measurements of the sample are highly precise but consistently 2% lower than the accepted value. Which conclusion is most strongly supported by all of the evidence?
