The Valence Shell Electron Pair Repulsion (VSEPR) Theory is a model used to predict 3-D molecular geometry based on the number of valence shell electron bond pairs among the atoms…

Alkanes are saturated open chain hydrocarbons containing carbon - carbon single bonds. Methane (CH4) is the first member of this family....

The term ‘hydrocarbon’ is self-explanatory which means compounds of carbon and hydrogen only. Depending upon the types of carbon-carbon bonds, they can be classified into three main.....

Balance a chemical equation. Recognize that the number of atoms of each element is conserved in a chemical reaction. Describe the difference between coefficients and subscripts in a chemical equation.....

Describe the relationships between volume and amount of solute to concentration. Explain how solution color and concentration are related. Calculate the concentration of solutions in units of molarity (mol/L).......

Explain how two gases mix. Design an experiment to find the factors which affect the rate of diffusion...

Determine how changing a variable among P, V, N, and T influences other gas properties. Describe the relationship between particle-wall collisions and pressure......

Explain how attractive and repulsive forces govern the interaction between atoms. Describe the effect of potential well depth on atomic interactions......

Recognize that molecule shape is due to repulsions between atoms. Recognize that bonds are not fixed in place, but can rotate around in response to repulsions.

Recognize that molecule geometry is due to repulsions between electron groups. Recognize the difference between electron and molecular geometry. .....
