Answer:
D Earth's hot interior
Explanation:
The internal heat engine of the earth is the energy source that powers plate movement.
The sun drives the surface process and provides energy for the external heat engine
- The earth's interior sources it heat from:
- decays of radioactive isotopes
- remnant heat from the formation of the earth
- frictional heating from the movement of the earth
Therefore, the heat is used to melt rocks and set up convection currents that drives plate movements.
<u>Answer:</u> The concentration of comes out to be 0.16 M.
<u>Explanation:</u>
To calculate the concentration of acid, we use the equation given by neutralization reaction:
where,
are the n-factor, molarity and volume of acid which is
are the n-factor, molarity and volume of base which is NaOH.
We are given:
Putting values in above equation, we get:
Hence, the concentration of comes out to be 0.1862 M.
