combustion of a .9827 g sample of a compound containing only carbon, hydrogen, and oxygen produced 1,900 g of c)2 and 1.070 g of h20. What is the empirical formula of the compound

Since there is the same amount of agn03 in both silver chloride and silver nitrate they produce the same amount of moles. therefore silver chloride produces the same amount of silver nitrate, so your answer is 15.0 moles of silver nitrate. i hope this !

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.

The answer is:   [d]:   "ultraviolet" {"  uv  "} .

The answer is a a and x i just took the quiz and it was right
