Ashley Huston ILab‚ Week #2 CATIONS AND ANION LAB Introduction The purpose of this lab is to demonstrate a double-replacement reaction of ionic compounds. In this experiment‚ you will combine two ionic compounds. Both compounds are soluble in water. If a response happens between these two compounds‚ then a precipitate will form because one of the two resultant compounds is not soluble in water. This is a hint that a reaction took place. Cations are positively charged ions that are attracted

African Diaspora and the World After reading the short story “Diaspora” by Joanne Hyppolite‚ I got a vivid understanding of how diaspora can have an effect on one’s identity. Over the past month we have studied many theories and concepts concerning race‚ gender‚ and politics. There are three theories that capture the essence of Joanne Hyppolite’s worldview as a Haitian growing up in America: intersectionality‚ identity‚ and diaspora. Individuals oftentimes experience the theory of Intersectionality

identifying the cations is called qualitative analysis. The purpose of this experiment is to identify which cations are present in unknown solutions. A data sheet was not prepared for this experiment‚ so you must record your observations in the lab notebook as you do the experiment. This experiment will last several laboratory periods. A.

Density (Linearized plot) TA: Blue Rex rex Group Members: Billy and Mandy Tuesday; 1200-1350 Abstract: In this lab the density of hand-made clay balls were calculated to understand how scientists model physical effects and to understand logarithmic plots. The hand-made balls ranged from diameters of 2cm to 6cm and were measured with vernier calipers by each member of the group. A total of 6 independent measures of each diameter were taken to establish uncertainty. The clay balls were then

certain task. In this lab we examined motor unit recruitment and muscle fatigue by electromyography (EMG) with dynamometry (DYN). When the motor unit in the muscle is activated signals are then generated‚ which result in muscle contraction. The impulse generated are a bit weak‚ yet can still be detected by the electrodes‚ EMG and is coupled by a measurements of power‚ DYN. When all the motor units reach its maximum strength the muscles will fatigue. Finally‚ the objectives of this lab were to determine
