In an experiment, potassium chlorate decomposed according to the following chemical equation. kclo3 → kcl + o2 (molar mass of kclo3 = 122.5 g/mol; kcl = 74.55 g/mol; o2 = 31.998 g/mol) if the mass of kcl produced was 180 grams, which of the following calculations can be used to determine the mass of potassium chlorate decomposed? (180 × 2 × 74.55) ÷ (122.5 × 2) grams (180 × 3 × 74.55) ÷ (122.5 × 2) grams (180 × 2 × 122.5) ÷ (74.55 × 2) grams (180 × 3 × 122.5) ÷ (74.55 × 2) grams

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.
