It is known that chlorine is more electronegative than bromine, and thus chlorine is more reactive, and less discriminatory as to what it will react with, thus making bromine more “selective”. Another pertinent piece of information to look at would be stability. The stability of a free radical increases as the number of carbon substituents increases. Therefore, primary is the least stable and tertiary is the most stable. Also, the more stable the free radical that is left behind, the weaker its C-H bond strength will be.
AS substrates are initially added, the activity is higher and then it reaches a plateau with increase. NO. Sucrase activity reached a plateau. Correct Predictions: Optimal temperature: 40 °C (104 °F), Sucrase activity increases with increasing sucrose concentration until a plateau is reached. Incorrect predictions: Sucrase will have highest activity at ph 6 not ph 7 Warm up exercise increases body temperature making it ideal for enzyme activity Increasing myosin activity makes muscles tougher and stiff and limits free movement for performance.
So I guess that wrapping the candy makes it melt more slowly. I was right that smaller candies melted more quickly. The small M&M only took 2 minutes to melt, but the bigger M&M lasted 5 minutes. All of the unwrapped,
In conclusion, the data from the goldfish respiration lab supports my hypothesis. My hypothesis was that if I were to put the goldfish in the 27OC water then the goldfish will breathe faster because the water is hotter and the molecules move further apart. Therefore, the fish will have to take more breaths. In 10OC water, the goldfish will take fewer breaths because in colder water the molecules move slower and they are closer together. As a result, it will have to take fewer breaths.
This causes the enzyme to be denatured and stop chemical reactions to further occur. The change of pH disrupts the fragile hydrogen bond in the secondary structure of the enzyme, also resulting the change in the tertiary structure of the enzyme. When the enzyme is deformed, it does not match up with the molecules anymore; as a result, the reaction
Puropose The purpose of this experiment is to see whether breaking the alka- seltzer into smaller pieces will decrease the time of making the canister cap pop. Hypothesis My theory about this experiment is that the more we break the reactant which in this case is the alka- seltzer into smaller pieces and then putting it to water will decrease the time it takes to pop the canister cap. This is because of the more we break something into smaller pieces the surface area increases causing more molecules to become available for collision. Apparatus/ * Digital weight * Canister * Scoopula Materials * Alka- seltzer * 10 ml Water * Stop watch Procedure 1.) Get all the materials and apparatus u need.
Liana Ortiz December 12, 2012 Balloon War In this project I will determine the effect on the rate of reaction. The rate of most chemical reactions will increase in higher temperatures, however this is not true for many other chemicals. The best temperature for each chemical reaction needs to be researched. Excess heat in many cases can lower the rate of reaction or even reverse the reaction. In some other cases excess heat may result in a different product other than what is expected.
For example, I always try to but Scotty’s toilet paper over other brands because I love the quality and it lasts longer than generic brands. 2. The Law of Supply-The relationship between price and quantity supplied, called the law of supply which can be summarized as follows: “At higher prices, a larger quantity will generally be supplied than at lower prices, all other things held constant. At lower prices, a smaller quantity will generally be supplied than at higher prices, all other things held constant (Miller, 2012, p.58). I’ve noticed that when items go on sale, they go faster than normal, and when it’s gone that’s it.
High-fructose corn syrup metabolizes to fat in the human body much faster than other sugars, resulting in increased fat gain. Since the fructose is consumed in liquid form, the negative effects on human metabolism are even greater (Barrett). High fructose corn syrup is not digested by the body as easily as natural sugar is. It takes the human body one day to digest natural sugar, while it takes up to four days to digest a serving of high fructose corn syrup. This means that your body is continuously working to digest high fructose corn syrup if the body consumes processed foods or drink soda on a regular basis.
Exercise increases your heart rate, which strengthens your heart HDL (high density lipids) “good" cholesterol and reducing your triglycerides, which can help lessen the buildup of arterial plaque. These benefits decrease your risk of developing heart disease in the future.Pulmonary changes Exercise not only increases your heart rate, it also increases your breathing rate. Like the heart, as your lungs work harder, they become stronger. This increases your ability to take breaths during rest times as well as during exercise. Stronger lungs mean you can similarly take more oxygen in.
