One major difference between the carbon, nitrogen, and sulfur cycles compared to the phosphorous, calcium and silica cycles is that the P. Ca, and Si cycles are NOT affected by global warming or other human activity the R. Ca, and Sicycles do NOT involve redox changes or gaseous forms that can alter Earth's atmospheric chemistry . Ca and Si are NOT cycled in terrestrial environments. the R. Ca and Sicycles do NOT involve microbial activity

A 3.93 gsample of a compound consisting of carbon, hydrogen, oxygen, nitrogen, and sulfur was combusted in excess oxygen. This produced 2.21 g CO2and 1.36 g H2O. A second sample of this compound with a mass of 4.72 g produced 4.84 g SO3. A third sample of this compound with a mass of 8.39 g produced 3.39 g HNO3. What is the empirical formula of the compound?

5. Compound X contains only carbon, nitrogen, hydrogen, oxygen and sulfur. Analysis experiments produced the following results: 1. 2.52 g of X burned in excess O2 produces 4.25 g of carbon dioxide and 1.02 g of water at 100% yield. 2. 4.14 g orx reacts to produce 1.785 g of sulfur trioxide at 85% yield. 3. 5.66 g orx reacts to produce 1.68 g of nitric acid at 75% yield. What is the empirical formula of compound X?
