2 As (s) + 6 NaOH (aq) → 2 Na3AsO3 (s) + 3 H2 (g)
If 34.0g of As react with excess NaOH at STP, what volume of H2 will be produced in liters?
SnO2 (s) + 2 H2 (g) → Sn (s) + 2 H2O (l)
What mass of water is produce when 79.0g of SnO2 are consumed in the reaction above?
C3H8(g) + 5 O2 (g) → 3 CO2 (g)+ 4 H2O (g)
What volume of oxygen is required to completely combust 0.499L of propane (C3H8) at STP?

The human eye contains a molecule called 11-cis-retinal that changes shape when struck with light of sufficient energy. the change in shape triggers a series of events that results in an electrical signal being sent to the brain that results in vision. the minimum energy required to change the conformation of 11-cis-retinal within the eye is about 164 kj/mol.
