C3H8 (g) + 4C12 (g) → C3H4Cl4 (g) + 4HCI (g) Molar masses listed for the above equation:
C3H8 (g) = 44.1 g/mol
Cl2 (g) = 70.9 g/mol
C3H4Cl4 (g) = 181.9 g/mol
HCI (g) = 36.458 g/mol
A 4.00 mol sample of C3H8 (g) and a 6.00 mol sample of Cl2 (g) are placed in a previously
evacuated vessel, where they react according to the equation above. After one of the
reactants has been totally consumed, how many moles of HCI (g) have been produced?

Agroup of students is studying convection current. they fill two identical balloons with the same amount of helium. one balloon is placed in a freezer and the other is in an area with warm air. after 10 minutes, the balloon are released from a height of 1 meter. which of the following to the students most likely observe? a) the warm balloon expands and rises. the cold balloon shrinks and sinks b) the balloon both rise. the cold balloon is larger than the warm balloon c) the cold balloon expands and rises. the warm balloon shrinks and sinks d) the balloon rise at the same rate. both balloons are the same size
