Answer:
Rhombic sulphur and monoclinic sulphur.
<span>According to Le Chatelier's Principle, the position of
equilibrium moves to counteract the change, the position of equilibrium
will move so that the concentration of
products of chemical reaction increase, if:</span>
<span>1) increase temperature, because this endothermic reaction.</span>
<span>2) increase concentration of reactant.</span>
<span>3) decrease pressure of the system, so reaction moves to direction where is more molecules.</span>

Answer:
Magnesium bromide, MgBr2, and water, H2O.
Explanation:
Hello!
In this case, since HBr is an acid and Mg(OH)2 is a base, an acid-base reaction is undergone, by which a salt and water are produced as neutralization products:
However, it need to be balanced since two bromine atoms are produced, therefore we write:
Thus, the products are magnesium bromide, MgBr2, and water, H2O.
Best regards!
