3. In this experiment, the percent yield was 90%. This number implies that there was little error in this experiment. However, this result could have been caused by certain external factors.
In the end, my results were very close to the actual values, which produced my low percent error of -3.0%. In conclusion, this lab experiment went well. I completed the objectives successfully, concluding with fairly accurate data, and thus a low percent error. However there is a small space for improvement within the construction of this lab, which possibly could have prevented the negative error I obtained.
The mass production of sugarcane had multiple effects on the American society, some of which were beneficial for the society while others caused issues and problems. Sugar became a new ingredient for daily uses, a way to earn money, caused an increase in slavery, and issues with the economy and environment. Overall, whether the outweighed effect was beneficial or harmful, the effect was a major impact on the American society. One effect sugar had on American society was its use as an ingredient. In the text it states, “...over the centuries it’s been a medicine, a spice, a symbol of royalty, and an instrument of disease, addiction, and oppression.”
The experiment went on for 26 days, and we fully observed on 3 days. To try to make the test fair, we tried to do what made the most sense considering that there can’t be a small jar’s worth of grass and water in a big jar. We kept the ratios of grass and water simple and mostly proportional to the size of the jars. Also, when observing, we took observations from multiple
How does sugar concentration affect yeast respiration rates? Hypothesis If I increase the sugar concentration then the yeast will produce more CO2 because the
Joshua Miller 12/18/17 Fermentation Lab report Introduction The term fermentation refers to the chemical breakdown of a substance by bacteria, yeasts, or other microorganisms, typically involving effervescence and the giving off of heat (wikipedia). Sugars are converted to ethyl alcohol when fermentation happens. In this experiment we determined if yeast cells undergo fermentation when placed in a closed flask with no oxygen. Glucose and yeast are mixed together in a closed flask and allowed to incubate for about one hour.
Hypothesis: An increase in the concentration of the acetic acid vinegar will cause a correlating increase in the volume of CO2 bubbles produced. Variables: Independent variable: 20%,40%,60%,80% and 100% concentrations of 20 ml vinegar Dependent: The volume (ml) of Co2 bubbles formed Controlled variables: 5 grams of Sodium Bicarbonate 20 ml of vinegar acid Apparatus used during the
Sugar is everywhere, often hard to escape from. As we focus on cutting out fat we look for low fat foods that often are just replaced with sugar. If we try and cut out sugar from our diet and read labels food industries hide the word sugar into many larger words that we don’t think anything when we see it. The label might say so much sugar but what sugar are you actually eating? These sugars are in ketchup, soups, breads, cookies, and almost all processed food.
From the very first traces of the chemical elements necessary for the creation of sugar, to the necessity of sugar for life, allowing the human race to survive and thrive, sugar was a profound discovery. Back when chemical elements were first created, select elements created a carbohydrate called sucrose, the basis of sugar. When life began appearing on Earth, plants that create sugar grew. When humans stopped moving around, they began to farm and harvest plants like sugar. And finally, humans took sugar and made it into something more and essentially something much better, and used it to interconnect societies during the modern revolution.
Yeast in dough is a catalyst. It causes a chemical reaction that makes the dough expand and rise. Jesus said that the Kingdom of God is like yeast mixed into dough to leaven it. You can't see it working, except in its effects. Without yeast the dough becomes a flat stone.
The proposed study is to seek a greater understanding on the awareness of added sugars in the diet of Americans and how they have a negative effect on the health of these consumers. Over the years, numerous studies (AHA, 2009; Dovey, 2015; Gunnars, 2013; The President and Fellows of Harvard College, 2018; Sack, 2013; Sergev, 2018; Stork, 2005; WSRO.org, 2012) have been conducted on sugar consumption and its effect on health. Simple vs. Complex Sugars According to The Dangers of Hidden Sugars, there are simple sugars and there are complex sugars. "Simple sugars are bad for you, and there are complex sugars that are excellent for you."
What is the effect of temperatures 10°C , 20°C, 40°C, 60°C and 70°C ± 1/°C on yeast fermentation when baking bread? ii. Aim: The focal aim of this experiment is to investigate the effect that temperature has on the growth and respiration of yeast (Saccharomyces cerevisiae) fermentation. iii.
