An herbicide contains only C , H, Cl, and N. The complete combustion of a 150.0 mg sample of the herbicide in excess oxygen produced 156.9 mL of CO2 and 91.52 mL of H2O vapor at STP. A separate analysis determined the 150.0 m sample contained 41.36 mg Cl. Determine the percent composition of the herbicide. Determine the empirical formula of the herbicide. The herbicide has a molar mass of 257.16 g/mol. What is the molecular formula of the herbicide?

Rocks, as they are compressed, begin forming mountains above the earth's surface when two continental plates converge. the continental crust increases in depth as the mountains grow above. the himalayan mountains formed at a convergent plate boundary in this manner. the rocks are smashed together causing them to due to the intense heat and pressure from the colliding plates and eventually forming rock. a) melt; igneous b) layer; sedimentary c) recrystallize; metamorphic d) melt into the earth's interior; metamorphic
