Lab 4: Le Chatelier’s Principle Name: Cammey Mahowald Lab Partners: None Date of Experiment: March 16‚ 2015 Course: CHE 112 Abstract: The purpose of this experiment is to understand the components of a reaction at chemical equilibrium and use Le Chatelier’s principle to predict the direction an equilibrium position will shift upon changes in the concentration‚ temperature‚ and pressure. It was determined that in the equilibrium of chromate and dichromate it is an exothermic reaction and in the

Lab 4: Endocrine System Physiology | 1. | | Refer to Activity 1: Determining Baseline Metabolic Rates. How did the baseline metabolic rates of the three rats differ? Answer: | The metabolic rates for the thyroidectomized and hypophysectomized rats were lower than that of the normal rat. | | | 2. | | Why did the metabolic rates differ? Check all that apply: Answers: | The hypophysectomized rat lacked thyroid-stimulating hormone. The thyroidectomized rat lacked thyroxine hormone.

I lab Week 4 Exercise 1 As most countries in the Asian and Pacific region‚ contemporary Mongolia is undergoing mobility transitions. Mongolia is in the midst of its demographic transitions and has pursued model of economic growth that has been more focused on import-substitution. In other hand‚ Mongolia is in demographic transition‚ witnessing a moderate‚ but decreasing‚ population growth‚ sustained decline in fertility and a steep increase in the number of young adults entering the labor market

The University’s systems and security infrastructure has given the IT analysis team a good start in building a security plan by gathering information about the University’s systems from the network diagram. A security control is any mechanism that you put in place to reduce the risk of compromise of any of the three CIA objectives: confidentiality‚ integrity‚ and availability. When you plan your network addressing scheme‚ consider the following factors: The type of IP address that you want

That is‚ the entering group does not for the most part have the same position on the ring as that purged by the halogen substituent. Case in point‚ the hydrolysis of 4-chloromethylbenzene at 340° gives an equimolar mix of 3-and 4-methylbenzenols: Significantly all the more striking is the elite development of 3-methoxybenzenamine in the amination of 2-chloromethoxybenzene.

Question 2.1: (i) Calculate the number of electrons which will together weigh one gram. (ii) Calculate the mass and charge of one mole of electrons. * ------------------------------------------------- Answer (i) Mass of one electron = 9.10939 × 10–31 kg Number of electrons that weigh 9.10939 × 10–31 kg = 1 Number of electrons that will weigh 1 g = (1 × 10–3 kg) = 0.1098 × 10–3 + 31 = 0.1098 × 1028 = 1.098 × 1027 (ii) Mass of one electron = 9.10939 × 10–31 kg Mass of one mole of
