Answer:
4560 Torr
Explanation:
<u>Boyle's Law</u>
where:
- = initial volume
- = final volume
- = initial pressure
- = final pressure
Given:
Substituting the given values into the formula:
To convert atm to Torr, multiply atm by 760:
N -3
Ba +2
Sr +2
F -1
I -1
Ca +2
Mg +2
S -2
S -2
Al +3
//
Ba3N2
SrF2
CaI2
MgS
Al2S3
//
I don't really understand 2.
<h2>Answer:</h2>
An increase in the population of prey means more food for predators, which will<u> increase</u> the predators' population. As a result, many more prey will be hunted, causing the prey population to<u> decrease.</u> In response, the predator population will <u>decrease</u>, resulting in an increase in the prey population.
<h3>Explanation:</h3>
The feedback loop is control of the system containing the prey and predator.
In this loop, the population of predator is directly proportional to prey but the population of prey is inversely proportional to a predators population.
As the population of prey increases, the population size of predator becomes large due to the availability of food. This inversely decreases the population of prey, as the predator do more hunt.
So the decrease in prey population results in a decrease in the predator population.

Answer:
Heavy stars turn into supernovae, neutron stars and black holes whereas average stars like the sun end life as a white dwarf surrounded by a disappearing planetary nebula. All stars, however, follow roughly the same basic seven-stage life cycle, starting as a gas cloud and ending as a star remnant.
