Answer #1

part A: (B) End to end overlap of p orbitals

part B:   (A) Side by side overlap of p orbitals

part C:    (E) Occurs when water is evaporated

part D: (B) Occurs when methane gas is burned

sigma bond is always formed with end on overlap of two p orbitals .

pi bond formed by side ways overlap always

physical change means the change which does not causes any change in composition of substance during evaporation of water it will not change in its composition.

chemical change is the chenge by which composition of substance will change.

Chemical Reactions Types and Their Equations Making Heat with Chemical Reactions Have you ever wondered how an instant heat pack works? A disposable heat pack works by a chemical reaction that combines iron in the package with oxygen from the air when the outer packaging is removed producing iron oxide. You have probably seen the product of this reaction in what is commonly called rust. The reaction releases heat, which allows the pack to reach a sufficient temperature that is...
