The reaction below is exothermic: 2SO2 (g) O2 (g) 2SO3 (g) Le Chtelier's Principle predicts that will result in an increase in the number of moles of SO3 (g) in the reaction container.

How many moles is 14.5 cm^3 of platinum? the density of platinum is 21.45 g/cm^3.

The famous scientist galileo galilei did several experiments with sloping planes, which he rolled metal balls down so that he could study motion. by changing the slope, he could study how the speed at which the ball rolled was affected. what was the independent variable in galileo's experiment? a. the speed of the ball b. the slope of the plane c. whether the ball moved d. what the ball was made of

If an atom has 12 protons and 13 neutrons
