Proteins are an essential part of all living organisms. Proteins are macromolecules made up of amino acid chains. These chains of amino acids are held together by peptide bonds to from polypeptide chains. Each proteins function is determined by its own unique three dimensional shape and active site. Proteins have multiple functions that are important to all cells.
The white candle burned faster because it has chemical materials in it. Result: The white candle burned slower than the coloured candle. The candles was 5.0cm before I burn it.
The question is, how does a physical or chemical change affect the mass of a substance within a closed system? To respond to this question, my group did a lab to determine whether or not the mass would change or not. Our lab was to have a plastic bag containing baking soda, then add a cup of vinegar and a block of clay to the mix. We made sure to weight every element separately and then add them up for our total mass of 31 grams before the reaction. During the reaction, as soon as the vinegar was poured in there was a gas produced, bubbles.
Different Mole Ratios And It’s Reactions Introduction: Chemical reactions play an important role when it comes to mole ratios.
In the experiment, the chemical rate will be between the baking soda and citric acid as state before. The temperate of the water will have a great effect on the reaction rate because it will either speed up the process or slow it down. The article the effect of temperature on reaction rates states, “As you increase the temperature the rate of reaction increases. As a rough approximation, for many reactions happening at around room temperature, the rate of reaction doubles for every 10°C rise in temperature” (The effect of temperature on reaction rates, 2013). The water that the scientist will be placing the bath bombs in will be room temperature and as soon as you increase that temperature, the rate will increase.
Lab Report By: Amiya Kamal 7B Purpose: The purpose of this experiment is to analyse different substances and see their reaction with each other substances. This experiment is also to examine the particle theory of each mixture.
Equation 3.1 can be simplified to the following equation γ(t,m;m_m )= e^(α-βm)/〖(t+c)〗^p (3.2) Where a_0=a+bm_m , α=a_0 ln10 and β=b ln10 are defined. |γ_m (t,m;m_m )|=|∂γ(t,m;m_m )/∂m|=e^α/〖(t+c)〗^p βe^(-βm) (3.3) Where |γ_m (t,m;m_m )| represents the absolute value of the partial derivative of γ(t,m;m_m ), and it is the instantaneous daily rate density of aftershocks of magnitude m at time t following a main-shock of magnitude m_m. e^α/〖(t+c)〗^p denotes the mean instantaneous daily rate of aftershocks at time t following the main-shock of magnitude m_m. βe^(-βm) is the exponential probability density function of aftershock magnitudes.
What type of chemical reaction will a balloon receive when filled with an acid and base? Acids and bases are around us everywhere in various types of liquids. They are in the foods we eat and the things we use on a daily basis, for example liquid dishwashing soap. Acids are usually sour and bases are silky, giving it a bitter taste. Water can act like both, depending on the situation.
The purpose of this experiment is to see which specific types of flammable liquid burns longer when contacted with
The second reason is that the nonmetals have smaller atomic sizes making it easy to attract electrons but difficult to pull them away. 12. A lot of energy is required to break a strong intermolecular bond. This is because atoms in certain compounds have very strong bonds that require energy to break.
Introduction The purpose of this lab is to use control variables to help identify different macromolecules. Biological systems are made up of these four major macromolecules: carbohydrates, lipids, proteins and nucleic acids. Carbohydrates are sugar molecules (monosaccharides, disaccharides, and polysaccharides) which make them the most abundant macromolecule on the earth. Lipids (oils and fats, phospholipids and steroids) are insoluble in water and perform many functions such as energy source, essential nutrients, hormones and insulators (Lehman, 1955).
Introduction Chiral molecules chemical structures that are non-superimposable mirror images of one another, much like the way a person’s hands are. Also known as stereoisomers, these compounds have the same molecular formula with different spacial orientation. Each chiral molecule contains a pair of enantiomers, each of which represents the two structures for each molecule (ie left hand and right hand). Chiral molecules play a huge part in pharmaceutical compounds, making up 56% of the drugs currently on the market with around 88% of these being classified as racemic ie. Has an equal amount of left and right hand enantiomers.
Proposed Work: The research that I am involved in is exploring the role and structure of the protein Perilipin 5, which is involved in lipolytic activity in oxidative muscles. The goal of my research is to uncover the N-terminal structure of the protein Perilipin 5. The value behind knowing the structure of a protein is great. Once the structure of a protein is fully comprehended, we can more fully grasp the impact and interactions that it has on other molecules in cells and, therefore, how the cell uses this protein in lipolytic activity.
Also, salt is an ionic compound and not a polar covalent compound, even though it did not melt last, due to the fact that the elements Na and Cl, both lose or gain an electron and then bond because of their opposite charges, which is a property only ionic bonds possess. The wax was the only substance whose results were synonymous with my hypothesis, since it required a low temperature for its melting point and was not soluble in water, both properties of nonpolar covalent compounds. Potential sources of error included not labeling the spots each substance was placed in the aluminum foil boat, seeing as the result for sugar seemed to be the correct conclusion for salt and vice versa. A future experiment would involve individually testing each substance in an aluminum foil boat, of the same brand, on a heat plate in order to avoid uncertainty. Each substance should be timed to record the precise time each substance began to melt or burn.
Properties of Substances Express Lab 1)The purpose of this lab was to compare the physical properties of different types of solids and how the properties of solids are determined by their intermolecular forces and their intramolecular bonds. Then we were to classify each type of solid as either ionic, metallic, non-polar molecular, polar molecular, or network. Paraffin wax classified as a non-polar molecular, Silicon dioxide was classifies as a network, Sodium chloride was classified as ionic, Sucrose was classified as polar molecular and Tin was classified as metallic. (2)The intermolecular forces that are present in Paraffin wax are dispersion forces, because it is non-polar and carries a negative charge. Followed by Sucrose that has
