Percent Error occurs due to many factors. In this lab by the graph I can state that there was a 100% error in all three unknown substances‚ Pure Leaf Lemon Tea‚ Sprite‚ and Tree Ripe Lemonade. This could be a result of not having properly zeroed the scale or the scale glitching when it came to zeroing it‚ which would have added extra mass and skewed the results. Another factor that could have resulted in a high percent error would have been the scale itself glitching which would have caused the wrong

result we predicted. In chemistry‚ this discrepancy is compared by calculating the percent yield. In this lesson‚ we will define percent yield‚ and go over a few examples. !!!What is Percent Yield? Sometimes you look at a recipe and it says how many servings it will make if you follow the amounts listed on there. There are times‚ however‚ that the number of servings after you have made the food is not the same as the one in the recipe. Different things may account for this difference – food spillage

Percent Copper in Brass Background The scientific concepts involved in this lab include Spectroscopy‚ Beer’s law‚ Calibration curve‚ concentration‚ and electronic transitions. The main objective of this experiment is to see how the percent composition of brass can be determined to verify the properties influenced by copper and zinc. Brass is a generic term for alloys of copper and zinc. The main technique used in this experiment is Spectroscopy. The three equations used in this lab are: Y = mx

Percent Composition Report Hypothesis : By using seperation techniques properly‚ the 3 substance such as; water‚ sand‚ and salt can be seperated and the percent composition of each substance. Which will then be calculated theoritically and after comparison with the actual result‚ the accuracy of the 2 result can be found. Aim : The aim of this experiment is to compare the gravimetric result of the original mixture and the separated substance. The other objective is to calculate each percent

Renewables contributed 19 percent to our energy consumption and 22 percent to our electricity generation in 2012 and 2013‚ respectively. Both‚ modern renewables‚ such as hydro‚ wind‚ solar and biofuels‚ as well as traditional biomass‚ contributed in about equal parts to the global energy supply. Worldwide investments in renewable technologies amounted to more than US$ 214 billion in 2013‚ with countries like China and the United States heavily investing in wind‚ hydro‚ solar and biofuels.
