Plz answer this. (No fake please)

120 moles of Mg

Explanation:

We'll begin by writing the balanced equation for the reaction. This is given below:

3Mg + 2H₃PO₄ —> Mg₃(PO₄)₂ + 3H₂

From the balanced equation above,

3 moles of Mg reacted to produce 3 moles of H₂.

Finally, we shall determine the number of mole of Mg needed to produce 120 moles of H₂. This can be obtained as follow:

From the balanced equation above,

3 moles of Mg reacted to produce 3 moles of H₂.

Therefore, 120 moles of Mg will also react to produce 120 moles of H₂.

Thus, 120 moles of Mg is needed for the reaction.

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
