Answer: -
Magnesium reacts very slowly to form magnesium hydroxide and hydrogen gas. The balanced chemical equation for the reaction is
Mg + 2H₂O → Mg(OH)₂ + H₂
Explanation: -
Chemical symbol of magnesium = Mg
Chemical formula for magnesium hydroxide = Mg(OH)₂
Chemical formula for hydrogen gas = H₂
The other reactant with Mg must be water H₂O.
Thus the balanced chemical equation for the reaction is
Mg + 2H₂O → Mg(OH)₂ + H₂
Au^2S^3+ 3H^2 = 2Au + 3H^2S
M = 22.1 g
V = 52.3 mL
D = ?
D = m/V
= 22.1/52.3
= 22.1*10/52.3*10
= 221/523
= 0.4
There. I’m sorry i forgot what exactly was the S.I. unit of density :(
Most likely the equation yields a new compound XY. This is a synthesis reaction. <span>Synthesis
reaction is a reaction where two or more substances combine to form a new
compound. It is a reaction which releases energy in the form of heat and
light. Therefore, it is an exothermic reaction.</span>
