let me know when u find out plz because i would like to know as well its one of my chemistry qustions in an assiment. :)
Answer:
2 moles of MgCl2.
Explanation:
We'll begin by writing the balanced equation for the reaction. This is given below:
Mg + 2HCl —> MgCl2 + H2
Now, we can determine the number of mole MgCl2 produced from 4 moles of HCl as follow:
From the balanced equation above,
2 moles of HCl reacted to produce 1 mole of MgCl2.
Therefore, 4 moles of HCl will react to produce = (4 x 1)/2 = 2 moles of MgCl2.
Therefore, 2 moles of MgCl2 were produced from the reaction of 4 moles of HCl.
Heat pumps most do work on a refrigerant in order to reverse the normal flow of thermal energy.
Answer:
Boiling occur as a result change in temperature
Explanation:
When a liquid is subjected to heat, the vibration between the liquid molecule started to moves.
The kinetic energy of the vibrating molecules increase as temperature increases. The molecules then begin to collide with each other. Effective collision also occur.
Thus the collision of the molecules as the result from vibration particle result in boiling
