A student is asked to balance an equation by using the half-reaction method. He determines the two half reactions as
shown below
2Br" >Br2 +2e"
Cl2 +2e- 201
What should he write as the final, balanced equation?
Cl2 + 2B- B2+2C1
Cl2 + 2Br +2 —>Br2+2cm
Cl2+28°——»Br2+201"+ 2e
Cly+Br"+2" —>Bry+C1"+ 20

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
