Lorenzo is making a prediction. “i learned that nonmetals increase in reactivity when moving from left to right. so i predict that xenon will be more reactive than iodine.” is lorenzo correct? if so, why? if not, explain his error.

How many liters of hydrogen gas will be produced at stp from the reaction of 7.179×10^23 atoms of magnesium with 54.219g of phosphoric acid (h3po4) the equation is 3mg + 2h3(> mg(po4)2+3h2

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.

The diagram below shows the different phase transitions that occur in matter. which arrow represents the transition in which dew is formed?
