2. Sulfur dioxide (SO2) gets blasted out of volcanoes and reacts with oxygen (O2) in our atmosphere to produce sulfur trioxide (SO3). If 128 grams of sulfur dioxide reacts with
oxygen in the atmosphere and 160 grams of sulfur trioxide (SO3) is produced, how many
grams of oxygen originally reacted?
SO2 + O2= SO3

The goal of this experiment was to answer the question "what is the effect of a gas' temperature on its volume? " you formulated the hypothesis below. hypothesis: if a fixed amount of gas is heated, then the volume will increase because the heat will cause the molecules of gas to move faster and further apart. to test this hypothesis, you changed the of the gas between 0 and 100°c (273 and 373 k) and calculated the resulting of the gas.
