How much sulfur trioxide (in grams) will form if 501.6 grams of sulfur reacts.

Work shown would be very helpful and greatly appreciated.

Which statement accurately describes the rock layers? layer 8 is older than layer 1. layer 3 is younger than layer 6. layer 4 and layer 10 are the same relative age. layer 2 and layer 9 are the same relative age.

In a sample of oxygen gas at room temperature, the average kinetic energy of all the balls stays constant. which postulate of kinetic molecular theory best explains how this is possible? a. attractive forces between gas particles are negligible because the particles of an ideal gas are moving so quickly. b. collisions between gas particles are elastic; there is no net gain or loss of kinetic energy. c. gases consist of a large number of small particles, with a lot of space between the particles. d. gas particles are in constant, random motion, and higher kinetic energy means faster movement.
