which statement best explains why rum can be used in cooking to serve flaming food?

rum is a very reactive liquid.
rum is a very dense liquid.
rum is a very volatile liquid.
rum is a very thin liquid.

Rum is a very volatile liquid

Explanation:

Rum is a highly volatile liquid and it catches fire very easily. Banana foster which is a flambe dessert is made by slicing banana and sauteed with brown sugar, cinnamon and butter and liquid rum is poured over it and lit. The rum burns off quickly and it is then served over ice cream. The rum catches fire instantly because it is highly volatile. It is serve to the customers in flaming form.

Thus, option "Rum is a very volatile liquid" is correct.

Explanation:

Elements which belong to same period show similar chemical properties.

This is because elements that lie in the same group have same number of valence electrons. Hence, they tend to show same type of reactivity which makes them exhibit similar chemical properties.

For example, F, Cl, Br and I are all members of group 17 and all of the contains 7 valence electrons.

Hence, they show similar chemical properties.

Thus, we can conclude that atoms of elements in the same group have the same valence electrons.
