vigorous exercise. During cellular respiration, glucose is broken down into CO2 (carbon dioxide). As CO2 (carbon dioxide) is bubbled through water, H2CO3 (carbonic acid) is formed. Because H2CO3 (carbonic acid) is a weak acid and dissociates in water, it forms HCO3- and H+ ions. As a basic solution is partially neutralized by an acid, phenolphthalein turns clear. Measuring the relative rates of the production of carbon dioxide before and after exercise can help us compare the rates of cellular respiration

Determination of an Equilibrium Constant Joseph Denning Group Participants: Maycie Hestand, Austin Prinkki, Kellen Wright Meeting Time: Friday 10:00 AM TA: Hannah Colmer Date: 26 February 16 Introduction In this lab, the equilibrium constant is determined for the following reaction between iron cations and thiocyanate anions: Fe3+ (aq) + SCN- (aq) ⇌ FeSCN2+. First of all, equilibrium is the balance of the macroscopic variables in a reaction; they don’t change over time. The reaction still

typically the pH of pure water. Plants typically have a specific tolerance for pH ranges in which they can flourish. Human activities such as coal mining have led to an increase in acid rain. According to Cary Institute of Ecosystem studies (2016), acid rain has caused the soils across the northeastern US to become increasingly acid which has had a detrimental effect on the growth rate of

Our task is to find out the number of pre-1982 pennies and post-1982 pennies inside a sealed vial. Firstly, we need to gather all materials that we need: Digital Scale, empty vial, and a sealed vial with pennies inside. If we’re supposed to estimate the number of old pennies and the number of new pennies, we have to measure what both of them weigh. We also needed to measure the weight of the vial itself, that is why we needed an empty vial. After we did the measurements, we found that an old penny

Of course, exotic oils-your basic Frankincense and Myrrh, for example-exert indescribable allure, magnetic attraction like the needle to the lodestone. Among essential oils for hair, however, two of the humblest herbs are exalted above the rest. Save the allure for later. Save your hair with jojoba oil and burdock. Jojoba Please, pronounce it "ho-HO-ba," and move it to the very tippy top of you're A-list; make it number one in your personal catalogue of essential oils for hair. You may have seen

pain, fever, and can also help prevent arterial and venous thrombosis (blood clots). In dry air it's quite stable, allowing it to be stored for long periods of time in medicine cabinets so it can be available whenever you need it. Acetylsalicylic acid binds to the serine in cyclooxygenases, which is how it can prevent inflammation and platelet accumulation- which can lead to blood

Use 25 pipette filler by attaching a 25 ml tube, pulling up the water by pushing the button on the pipet to make it go up to 25 ml and let go of the button. 250ml of water You pour 250 mls of water in a 250 ml graduated cylinder or you can use the pipette filler by attaching a 100 ml, 100 ml, and 50 ml serological pipettes to the pipet gun. Attach the one tube at a time (Do not use the same tube more than once) Pull the water up by pushing the botton up and when it reach the measurement then stop

Statement of the problem: In this experiment, we are trying to figure out how many droplets of water a penny can hold while face up. Before we began the experiment, we already knew that water molecules stick together as long as gravity isn't stronger than the water. In the experiment we had water, soapy water, and rubbing alcohol. Hypothesis: My hypothesis was that the water will have the most amount of drops and the soapy water will have the least amount of drops. Materials: The materials that

Task 1: a) Acids and bases play a large and important role in our body through various biological processes. After a human being consumes food, the food gets transported to the stomach where the border cells located there start producing Hydrochloric Acid (HCl) which is an acid that aids in the digestion of the food. In order to buffer or neutralize this highly-acidic chemical, those same border cells also secrete a base called Sodium Bicarbonate (NaHCO3) at the same time thanks to their dual function
