Use the following information to answer question 42-45
A Science 30 student is provided with three unknown substances. He is told that the
identities of them are methanol, methanoic acid, and methyl methanoate,
Methanol(CH3OH)
Methanoic acid(Ch-Oh-OH)
Methyl methanoate(CH-O-O-CH3) it’s a drawing of the chemical structure of this but I can’t draw it here
To identify what each of the unknown substances is, he performs a conductivity, litmus,
and odour test on each of the substances.
Conductivity Test
1 - Positive
2 - Negative
Litmus Test
1 - no change
2 - red turns blue
3-blue tums red
Match the descriptions below to the correct results from the tests above:
42. Conductivity of methanol
43. Litmus test of Methyl methanoate
44. Conductivity year of Methanoic acid
45. Litmus rest of methanoic acid

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.
