Answers 1. I would report that the company was profitable but only because Carmen did not pay herself $1‚300 per month or pay back any of the $10‚000 short term loan. The assets in the company increased by $1‚768 meaning that the company generated a Profit. The investment of Cash into machinery (Computer and sowing machine) caused the negative bank balance‚ if these assets were sold and put back into the company the bottom line would be better. It is hard to tell whether things are getting better

iLab‚ Week # 3 ATOMIC WEIGHT OF MAGNESIUM LAB Introduction The purpose of this lab experiment is to determine the atomic weight of magnesium by measuring the amount of hydrogen gas evolved when hydrochloric acid reacts with magnesium. The reaction is as followed: Mg + 2HCL H2 + Mg2+(aq) + 2Cl-(aq) In this experiment there is a one to one relationship between the number of moles of hydrogen gas evolved and the moles of magnesium metal consumed in the reaction. Therefore in the finding of the

Magnesium Oxide: Origin‚ Production and Utilization Magnesium oxide is a basic or alkaline kind of earth metal that naturally originates from seawater. The compound is odorless and colorless that makes it difficult to see by the naked eye. To produce such compound‚ extraction from the seawater by electrolysis and several chemical processes id done. The compound is formed from the thermal processes which make uses of air and oxygen. Magnesium hydroxide is also produced. The versatility of uses of

COMBUSTION OF MAGNESIUM OXIDE DESIGN Aim/Purpose: To calculate the number of moles and the empirical formula of magnesium oxide. Safety precautions: 1) Wear lab coat 2) Wear gogles. 3)Make sure the bunsen burner is working properly and their is no leakage. 4) Wear gloves. Hypothesis: The weight of the magnesium ribbon increases after burning‚ so this indicated that their was a change in mass. This change happened because of the magnesium ribbon inside the crucible which reacted with Oxygen

ATOMIC WEIGHT OF MAGNESIUM LAB Introduction The main purpose for this experimental lab is to determine the atomic weight of magnesium‚ as well as an underlying purpose in determining the relationship between moles evolved and consumed. This can be demonstrated by measuring the hydrogen gas evolved by performing a chemical experiment when hydrochloric acid reacts with the magnesium. The formulated reaction includes; Mg + 2HCl → H2 + Mg2+(aq) + 2Cl- (aq) The major findings contributing
