I. Abstract This experiment aimed to determine the composition of Ni2+- ethylenediamine (en) complexes through Continuous Variations method as well as the number of ligands (n values). This nondestructive method is preferred in determining the amount of complexes present which will also not disrupt the equilibria. 0.3M concentrations of nickel sulfate hexahydrate and ethylenediamene are mixed at certain stoichiometric ratios of 0.3‚ 0.4‚ 0.5‚ 0.6‚ 0.7‚ 0.8 and 0.9 to form several complexes.

How does variation play a role in population’s phenotypes? Phenotypes are characteristics of an organism which we notice through different physical features such as hair color‚ body weight‚ capabilities‚ the way someone might behave‚ etc. Variation is the differences in an individual in the population‚ Variation plays an important role in phenotype because it helps us understand life.‚ we see a variety of attributes everywhere each one mirrors an alternative important reason. For example‚ a bear

The first song “Variations on God save the King” was composed by Paganini and played by Ruggerio Ricci on the violin did not sound like there was any tonality. I did hear a pattern which means it had a meter. The dynamics was soft because if I remember correctly it means a small amount of instruments or singers. The tone color was a violin and flute. There was a theme since it kept repeating itself. The tempo was Rubato. I can hear a chord that was all I was able to make out. The song is not pleasing

Although many consider the Old West violent and bad‚ it was actually a mix of the good‚ the bad‚ and the ugly. The Old West began in the 1860’s up until 1890. It was also called the Great Plains and stretched from west of the Mississippi River all the way to Rocky Mountains. Many Americans traveled out west in search of adventure and a fresh start. There were a variety of job opportunities available‚ such as becoming a farmer‚ miner‚ or railroad worker. In the Old West‚ violence was prevalent‚ but
