Answer:
A physical property is a characteristic of matter that is not associated with a change in its chemical composition.Examples of physical properties include density, color, hardness, melting and boiling points, and electrical conductivity. We can observe some physical properties, such as density and color, without changing the physical state of the matter observed.
Explanation:
sulphur has a low melting point.
sulphur has a low boiling point thus it can be extracted by pumping hot water which turns it ito solution form
In a reaction with bromine, antimony will oxidize itself to +III oxidation state forming {antimony (III) bromide
Sb(s)+Br2(l)→SbBr3(s)
Balance the equation by balancing Bromine.
2Sb(s)+3Br2(l)→2SbBr3(s)
A balanced equation is an equation for a chemical reaction in which the number of atoms for each element in the reaction and the total charge is the same for both the reactants and the products side. In other words, the mass of the elements and the charge on them are balanced on both sides of the reaction.
A chemical equation needs to be balanced because a chemical reaction is just a rearrangement of atoms of the given elements. The chemical equation needs to be balanced to follow the law of conservation of mass.
