To determine the percentage by mass of Calcium carbonate in an egg shell Aim: is to find and work out the percentage of calcium carbonate by mass in eggshells by using acid base “back titration” Introduction: Calcium Carbonate‚ CaCO₃‚ is a compound which is polymorphic and therefore means that it can be found in a variety of different objects or organisms. For example: Rocks (limestone‚calcite)‚ sea snail shells‚ Eggshells‚ pearls and many more. This investigation will focus on finding out the

Problem 1 c) Notes to the Financial Statements: 1. The company uses the straight-line depreciation method. The rental equipment is estimated to have a useful life of eight years. Thus‚ the monthly depreciation of the rental equipment is 240‚000/96‚ or $2‚500 per month. 2. The note payable to Rent-It is good for one year. $100‚000 and the accumulated interest are due on November 30‚ 2012. The account payable for office supplies is due in thirty days‚ or January 2‚ 2012. The account payable

production. Overhead can be fixed‚ variable and semi variable. As volume changes‚ the different overhead cost behavior patterns cause per-unit manufacturing cost to fluctuate considerably. As a result‚ some method is needed to determine an amount of overhead charged to the units produced. ❖ Use of a Predetermined Overhead Rate ▪ Because of the impossibility of tracing overhead to specific jobs or specific products‚ overhead cost is allocated across jobs and units.

its constituent elements. The purpose of this lab was to test for law of definite proportion through determining percentage composition of each element in Magnesium oxide. I hypothesized that the composition mass of magnesium will be more than oxygen and this would be the result for other groups as well. My null hypothesis was that if the experiment is done accurately‚ the percentage composition of magnesium shouldn’t exceed 65%. Material: -Refer to lab manual on page 180 in Nelson Chemistry 11
