Determine if the data are qualitative or quantitative. Zinc is a silver-gray metal.

Chlorine has a density of 3.2 g/L.

Gallium is not found in nature.

Nitrogen has a melting point of –210.00°C.

Aluminum is a solid.

Dsolubility let me know if you have any other questions for chemistry

Yeah, but what are you trying to ask?

Radon-222 or rn-222 has a half-life of 3.82 days. to determine the fraction of an original sample of rn-222 that remains unchanged after 7.646 days, we calculate the amount of rn-222 remaining after 7.646 days and divide it with the original amount. using 1 gram as a basis and using half-life calculation methods, we can determine that  0.249 or 0.25  grams of rn-222 will remain, and thus the fraction remaining is 0.25 or 1/4.

Those are different gas lawshere is a brief description of themcharles's law states that volume and temperature are directly proportional to each other as long as pressure is held constant.  boyle's law asserts that pressure and volume are inversely proportional to each other at fixed temperature.gay-lussac's law introduces a direct proportionality between temperature and pressure as long as it is at a constant volume.    source:
