Answer:
Decrease
Explanation:
The lower you go, the colder because the sun can't reach lower levels of the ocean.
Answer:
decrease
Explanation:
less sunlight will be able to reach the farther down you go and the less sunlight there is the colder it gets
Which salt is produced when NH OH reacts with HNO3?
A: KNO2
B: NaNO3
C: NH4NO3
D: NH4NO2
Answer:
C. NH4NO3 ammonium nitrate is formed when the two acid and base react
What kind of reaction is this?
Answer:
Single replacement
Explanation:
Chemical equation:
2Al(NO₃)₃ + 3Ca → 3Ca(NO₃)₂ + 2Al
Single replacement:
It is the reaction in which one elements replace the other element in compound.
AB + C → AC + B
All other options are incorrect because,
Double replacement:
It is the reaction in which two compound exchange their ions and form new compounds.
AB + CD → AD +CB
Synthesis reaction:
It is the reaction in which two or more simple substance react to give one or more complex product.
Decomposition reaction:
It is the reaction in which one reactant is break down into two or more product.
AB → A + B
Combustion reaction:
Reaction in substance react with oxygen and form carbon dioxide and water.

diffusion in solids
have a great day
Answer: Well,diffusion does not happen in solids because the particles are not free to move around and so they cannot inter-mix.

The amplitude of a wave is
A. the distance between the crest and the trough of the wave
B. the distance the wave moves in one second
C. the distance equal to one wave length
D. the distance the wave moves in one time period of the wave
Answer:
the answer is A.
Explanation:
I hope this helps have a fantastic day!
Answer:
None of these
Explanation:
Amplitude is the distance from rest to crest.
Option A isn't the right answer
Option A is wavelength
JJ thomson experiment the atomic theory?
How many moles of Zn are there in 4.50 x 1024 atoms?
Answer:
7.48 molesExplanation:
To find the number of moles in a substance given it's number of entities we use the formula
[tex]n = \frac{N}{L} \\[/tex]
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
[tex]n = \frac{4.5 \times {10}^{24} }{6.02 \times {10}^{23} } \\ = 7.475083...[/tex]
We have the final answer as
7.48 molesHope this helps you
Roller coaster cars move slowly at the top of the hill, so they have little kinetic energy. The speed of the cars increases as they move down the hill. This increased the cars' kinetic energy. Where might this extra kinetic energy have come from?
a.) kinetic energy was added by pushing the cars
b.) potential energy was transformed into kinetic energy
c.) the cars always had kinetic energy
d.) kinetic energy was transferred into potential energy
Answer:
b.) potential energy was transformed into kinetic energy
Explanation:
According to the law of conservation of energy, energy is neither created nor destroyed but transformed from one form to another in a system.
So, in this system, energy is not created neither is it destroyed.
The increase in kinetic energy of the car is due to the conversion of potential energy to kinetic energy. Potential energy is due to the position of a body. As the car winds down the hill slope, the potential energy is transformed to kinetic energy. Also, the velocity of the body increases.
