    was to determine the mass percent composition of the mixture using a chemical reaction and stoichiometry mixture Na2CO3 and NaHCO3. To do the lab by using the constant mass. Constant mass is a quantitative chemistry technique where a single chemical species or group reactants is heated with constant weighing until the mass does not change. After heated the Na2HCO3 will undergo a decomposition and Na2CO3 will not undergo reaction. The balanced equation is 2NaHCO3NaCO3+H2O+CO2. Find the mass…

    information about chemical reactions and how a catalyst is used to speed up reactions. We have learned that enzymes (proteins) in eukaryotic cells work as a catalyst to make this possible. Each enzyme in a eukaryotic cells has specific molecules it binds to, as they have a specific frame work. This specific frame work of the enzyme is known as the active site, designed to fit very specific substrates (molecules). This creates the enzyme-substrate complex where the chemical reaction takes place.…

    In this experiment, the effects of environmental conditions on enzyme activity are explored. An enzyme is better known as an element produced by a living organism that acts as a catalyst to bring about a specific biochemical reaction. The environmental condition that was examined were the effects of temperature on enzyme activity. The raw materials that were used in this experiment were potato pile used to create catechol oxidase, catechol, and water which added as the solution. With Pipets and…

    could have negative effects on the cell, and could pose a health threat to the organism. Enzymes proteins that speed up chemical reactions by lowering the activation energy. They do this by acting as a template for substrate orientation, stressing the substrates and stabilizing the transition state, providing a favorable microenvironment, or participating directly in the reaction. All of these methods are implemented by the enzyme binding to the substrate or substrates. Substrates bind…

    Describe, briefly two cellular reactions that involve ATP hydrolysis (you will probably find the answer more quickly on Google than in your book). ATP is simply a renewable resource which is actually rejuvenated when adenosine diphosphate is mixed with a phosphate group. On the other hand, ATP hydrolysis is basically a method used by the human body to be able to release energy chemically to some other body parts in order for life to be sustained. In the process, ATP is actually converted…

    What does an award mean to a person? An award could mean a person was successful; such as, moving to the next step in a career. A reward could also mean recognition for a simple action given; such as, showing up to class. These rewards for showing up to class, one may feel that these are participation trophies. While participation trophies may boost a child's self-esteem, children grow up believing goals in life are easy to come by and no matter how hard they try, they still receive credit;…

    In the chemical reaction baking soda and vinegar, many different things are happening. When baking soda is added to vinegar almost instantaneously the reaction starts. One of the first observations a white foaming substance. This occurs because one of the products CO2(g) is releasing causing bubbles to form. Once the reaction settles a clear-ish liquid can be seen the products that are left behind to form this liquid are H2O+NaCH3COO(aq). The full balanced chemical equation is…

    living things, which makes it hard for biochemical reactions to happen at a faster rate. Enzymes help biochemical reactions speed up.An enzyme works by lowering the amount of activation energy needed to start a chemical reaction.Activation energy is the minimum amount of energy needed for the reactants to begin a chemical reaction. Normally, biochemical reactions would take many days, but with enzymes doing their job correctly, the same reaction is able to happen in seconds. The different jobs…
