Answer:
The invasive species would take over in the area and throw off the balance of the ecosystem.
Explanation:
Invasive species can harm both the natural resources in an ecosystem as well as threaten human use of these resources. An invasive species can be introduced to a new area via the ballast water of oceangoing ships, intentional and accidental releases of aquaculture species, aquarium specimens or bait, and other means.
Invasive species are capable of causing extinctions of native plants and animals, reducing biodiversity, competing with native organisms for limited resources, and altering habitats. This can result in huge economic impacts and fundamental disruptions of coastal and Great Lakes ecosystems.

How many moles are there in a 122 gram sample of nickel (Ni)?
7.16 x 103 moles
6.22 mol
2.08 mol
0.481 mol
Answers
The atomic mass of nickel is 58.71 gm and the given mass of nickel is 122 gm. Therefore, 2.08 moles are present in a 122-gram sample of nickel.
Nickel:
The atomic number of nickel is 28.The symbol of nickel is Ni.Density of a nickel 8.908 g/cm3.It is a d block element.It belongs to group 10 and period 4.It is also called transition metal.It is a metal and is located between groups 2 and 3.Mass of nickel given: 122 grams.
Atomic mass of nickel: 58.71 g mol
Number of moles = Mass / molar mass
= 122/ 58.71
= 2.078
= 2.08 moles.
The atomic mass of nickel is 58.71 gm and the given mass of nickel is 122 gm. Therefore, 2.08 moles are present in a 122-gram sample of nickel.

According to Coulomb’s law, what will happen to the electric force between
two identical negative charges as they move closer together?
A. Fe will become negative and decrease in magnitude.
O B. Fe will stay negative and increase in magnitude.
C. Fe will stay positive and increase in magnitude,
D. Fe will become positive and decrease in magnitude.
Answers
Answer:
C. Fe will stay positive and increase in magnitude.
Explanation:
Coulomb's law states that the force of attraction of repulsion between two charged particles is directly proportional to the magnitude of their charges and inversely proportional to the square of the distance of separation between them.
This means that if the size of the charges are large, the force acting on them will be large as well. Also if the distance between the two charges increases the force decreases. However, the force increases when the distance of separation decreases.
Like charges repel, therefore, two negative charges brought together will repel each other, and the distance between the two charges decreases, the force will increase in magnitude. Forces of repulsion are considered positive, therefore, the force, Fe, will stay positive and increase in magnitude.

A car is traveling at 50mph. How long will it take the car to travel 300 miles?
Answers
Answer:
6 hours
Explanation:
If it is traveling at 50mph and needs to reah 300 miles, to figure this problem out you would want to divide 300 by 50 to get 6 hours. So it will take six hours until the car travels 300 miles
Hope this helps.
Answer: A car travels at a rate of 50 miles per hour. how long will it take the car to travel 300 miles?
Explanation: .
Applying the distance formula:
d = rt
where
d is distance (300 miles)
r is rate (50 mph)
t is time (hours)
.
300 = 30t
300/30 = t
10 hours = t

_____________________________________As the option says, the kinetic energy will decrease. the volume decreases because the molecules are slower and collide less. Less molecules make the effective collisions due to which the kinetic energy of molecules is less, so less kinetic energy results in the shrinkage. So decrease in temperature lowers the rate of the reaction and in the volume.
