hybridization they have. The three main groups of Hydrocarbons are Alkanes‚ Alkenes‚ and Alkynes (1). Alkanes are sp3-hybridized hydrocarbons characterized by single bonds between carbon atoms included in their chains. Alkanes are also called saturated hydrocarbons because they contain the highest possible H atoms that they can since their single bonds give the Carbon atoms the opportunity to bond with three or two hydrogen atoms. Alkenes on the other hand are sp2-hybridized substances that are

More specifically‚ Calcium is needed for bone and teeth health‚ it gives your bones strength and density. According to BBC reports‚ calcium deficiency causes bones to become less dense and brittle which increases the risk of fractures. Iron is included in red blood cells‚ therefore it is extremely important because red blood cells

In this experiment‚ we took two TUMS tabs and through a back titration‚ we were able to find out how much acid was needed to neutralize two tablets of TUMS. In the first process of the titration‚ we added excess HCl and then we had to back titrate it by adding NaOH. We had to do a standardization test because the NaOH has a high reactivity and that could cause a small change. The NaOH solution was supposed to have a molar concentration of .5 however when we standardized the solution we found the
