Which term is defined as the change in the direction of light when it goes from one medium into a different medium?
vovikov84 [41]
The term defined as the change in direction of light when it goes from one medium into a different medium is refraction.

Refraction is the change of direction on the propagation of a beam of light when it passes from a medium to other; this only happens when the light travels at different speeds in both media.

When a beam of light that travels in the air incedes in a slab of glass, part of the beam is reflected (bounces) and part is refracted (it penetrates in the glass and changes the angle).


Also,due to the different speeds of light in air and water, when a beam of light passes from air to water, it refracts.

B. from 52 moles of nitric acid, how many moles of silver nitrate will be produced?
IceJOKER [234]

Answer:

39 mol AgNO3

Explanation:

We have the equation 4HNO3 + 3Ag -----> 3AgNO3 + NO + 2H2O

We want to calculate the number of silver nitrate (AgNO3) moles that would be produced from 52 moles of nitric acid ( HNO3 )

We can calculate this by using mole ratio as well as dimensional analysis.

The mole ratio of Silver nitrate to nitric acid based on the balanced equation is 3AgNO3:4HNO3.

Using this we can create a table: The table is attached.

Breakdown of the table.

The moles of nitric acid cancel out and we multiply 52 by 3/4 to get 39 moles of Silver nitrate.

Why does air have different pressures
