Question:

What is the basic difference between sp, sp2, and sp3 hybridization on a carbon atom?

Mia E.

A carbon atom always needs 4 bonds for it to be stable. Sp hybridization is a carbon with a single bond and a triple bond. Sp2 hybridization is a carbon atom with two single bonds and one double bond. Sp3 hybridization is a carbon atom with four single bonds.

Question:

What term is used to describe the minimum energy needed by particles when they collide on order to cause a reaction?

Mia E.

Activation Energy. Imagine two basketballs hit each other and simply bounce off each other: This is similar to what happens when two molecules come into contact. However, for a collision to be successful, a chemical reaction needs to occur and the molecules colliding hav e to have enough energy to break chemical bonds. This is because in any chemical reaction, chemical bonds in the reactants are broken and chemical bonds in the products are formed. So to create a reaction, the reactants need to be moving with enough speed that they can collide with enough force to break the bonds. The minimum energy that these molecules/particles need to be moving in order to cause a reaction is called activation energy.

Question:

Solve for the value of a using the equation a = 2 - 9a

Mia E.

First put all alike variables on the same side of the equation. Thus a + 9a = 2, which makes the equation 10a = 2. Then get a by itself by dividing 10/2. Thus a = 10/2 which simplified equals a = 1/5
