Crust
Core
Explanation:
For any terrestrial planet, the crust would be the coolest layer and the core would be the hottest layer.
Terrestrial planets or the inner planets made up rocky balls. They have layers that are differentiated.
Typically, they are made up of crust, mantle and the core.
The crust is the outermost layer.
The mantle is the middle layer and core is the inner most layer.
These planets are Mercury, Venus, Earth and Mars.
The outermost layer is usually the coldest part.
The innermost layer is the hottest part which is the core

The answer is ( The concentrations of the products and reactants do not change.)
Answer:
Single replacement reaction
Explanation:
By right, it should be called displacement reaction or redox reaction. Metal ion A in solution is reduced to form solid metal A while metal solid B is oxidised to form metal ion B.
Only 1 type of replacement occurred so it should be single replacement reaction
<u>Answer:</u> The result of the given calculation is 
<u>Explanation:</u>
Scientific notation is defined as the notation in which a number is expressed in the decimal form. This means that the number is always written in the power of 10 form.
We are given an expression:
The operation carried out in the above expression is division operation. The units are also treated in the same way.
The solution for the above expression is:
The value in scientific notation is
Hence, the result of the given calculation is
Answer:
A. 0.65g/mL, float
Explanation:
Mass: 325g
Volume: 500mL
D = m/v
D = 325/500
D = 0.65
Therefore, the block has a density of 0.65g/mL and it will float since the density of water is greater than the density of the block.
