chemical reactions. General properties of a base are Concentrated or strong bases and are caustic on organic matter and react violently with acidic substances. Also bases can are bitter in taste. And the pH of a basic solution at standard conditions is greater than seven. Strong bases are a basic chemical compound that can remove a proton (H+) from (or deprotonate) a molecule of a very weak acid in an acid-base reaction. Example of a strong base is lithium hydroxide‚ calcium hydroxide and strontium hydroxide

Introduction A complex ion consists of a metal ion with Lewis bases attached to it. These Lewis bases form strong coordinate covalent bonds with the central complex ion in which both electrons of the bond are donated by the Lewis base. The Lewis bases that form this complex are referred to as ligands and they are typically either neutral molecules or anions. Polydentate ligands have multiple lone pairs of electrons that enable them to bond multiple atoms to the central metal atom. The stability

Experiment A Spectroscopic determination of Iron with Phenanthroline Unknown # 2 Mass of Mohr’s Salt: 0.2040 1. 5mL of 6M acetic acid was measured and transferred into a 100mL volumetric flask with a pipette and diluted to the mark. Concentration = [0.2040(±0.0001)g/100(±0.08)mL]*[(1mol/392.16g)/(1L/1000mL)] = 0.005202(±0.09382%) = 0.005202(±0.000005)mol/L 2. 10mL of the above stock solution was transferred to a 250 mL volumetric flask and diluted to the mark.

1. The Strong Interest Survey was developed in 1927 by E. K. Strong Jr. This test assesses a person’s interest in four main areas. Those areas are general occupation themes‚ basic interest scales‚ personal style scales‚ and occupational scales. Each of these categories has a different number of questions but that total number of questions is 291. This test is done online only and takes 30-45 minutes to complete. The age range that is appropriate for this test is 14 and older. The survey is an individually

Throughout my years of school‚ I had always been a strong math and science student getting very high grades on mostly every test. From eighth grade till tenth grade I did well in math classes including algebra‚ geometry‚ and trigonometry. Going into my junior year I didn’t expect my honors pre calculus class to be a struggle. I assumed it would be similar to trigonometry and algebra and relatively more of a review class. Starting with the first test I did not receive a high grade like I was expected
