Belong to the group of alkyl sulfates. They can create soap bubbles and are soluble in water. It can be found in fabric softeners, shampoos, shower gels, dishwashing solutions, and detergents. This cleaning product provides the chemical energy to help clean and remove food soil from different types of cooking and serving items. 6. Cleaning product This can prevent the spread of infectious diseases and control allergens, such as dust 7. Detergent Prod- ucts This helps to disinfect and sanitize the materials and fur- niture in our home. 8. Amine oxides Possess a polarity that is similar to that of quaternary ammonium salts, making them extremely polar molecules. 9. Ammonia Is an inherently occurring, colorless, soluble alkali gas in the environment. It is a chemical made up of three hydrogen atoms bound to one nitrogen atom. 10. Sodium hypochlorite An additional alkali disinfectant is bleach. The molecular connections that hold stains and bacteria together are oxidized or broken away by bleach. 11. Phenols They resemble alcohols but create more robust hydrogen bonds. They have higher boiling temperatures and are more soluble in water than alcohols. 12. Ethol Physical Science Reviewer: Part 2 2 / 7 Is a naturally occurring substance that is created by plant fermentation using ethylene's hydration. 13. Quats Also known as quaternary ammonium compounds, are a class of low-level. As per Spaulding, disinfectants are the source of most quats Benzoalkonium. 14. Antibacterial/Dis- infecting Ingredients It provides further reduction in germs on the surfaces in our homes. 15. Sodium Percar- bonate Is a powder that releases oxygen through hydrocarbons, and extremely focused. This powder, which comes in the form of grains, works well for removing stubborn stains and muck off plates. 16. Ammonia Fumes These are strong irritants that might damage your nose, eyes, throat, lungs, and skin. 17. Alcohol Ethoxy- lates Belong to a class of substances that are widely utilized in both commercial and industrial settings. 18. Chemical Reac- tion Happens when reactants and products have sufficient energy to form. 19. Preservatives A substance that is added to a cleaning product in order to make it stable and safe for a longer period. 20. Thickeners Gives soap the proper viscosity (thickness), making sure it can still flow out of a bottle. 21. Greater than 7 pH of a certain product to be considered as basic. 22. Builders It helps the surfactants become more powerful by interact- ing with substances 23. Enzymes It is a powerful stain-removing ingredient 24. Dye A common ingredient do cleaning products use to give them color and make them more interesting to use. 5 / 7 5 48. Non-renewable Source Natural resource that cannot be readily replaced by nat- ural means at a quick enough pace to keep up with con- sumption. 49. Solar power Is a variable energy source that is dependent on the cycle of the sun. 50. Reactant A substance that takes part in and undergoes change during a reaction. 51. Product Refers to the substance that are formed as a result of a chemical reaction. 52. Chemical Reac- Chemical reaction deals with the process that involves tion rearrangement of the molecular or ionic structure of a substance, as opposed to a change in physical form or a nuclear reaction. 53. Chemical Equa- It is used to describe a chemical reaction into formulas and tion symbols. 54. Yield Refers to the amount of product obtained from a chemical reaction compared to the theoretical maximum amount predicted by stoichiometry. 55. Reagent Any substance that is added to a chemical reaction to induce a chemical change. 56. Percentage Yield Is the percent ratio of actual yield to the theoretical yield. 57. Theoretical Yield The maximum amount of product that could be formed from the given amounts of reactants. 58. Actual Yield The amount that is actually produced in a reaction 10. Stoichiometry- is a branch of chemistry that establishes mole and mass relationships between reactants and/or products in a chemical reaction to determine desired quantitative data. 59. Excess Reagent 6 / 7 6 Is a reactant that is not used up when the reaction is finished. 60. Limiting Reagent Is a reagent that is completely used up in a chemical reaction. 61. Mole A mole, similar to the english system, it represents a value of measurement in chemistry, which is avogradro's number 6.022×10 ̂ 23. It is used to measure and compare the amount of particles in a molecule. 62. Mass It is the measure of the amounts of particles of a matter. In chemistry, grams is the unit of measurement used to chemical equations. 63. Ratio A ratio is a comparison between two quantities by division. 64. Grams A unit of mass in the International System of Units (SI) equal to one thousandth of a kilogram. 65. Balanced Equa- An equation that has equal number of atoms of each ele- tion ment on both the sides of the equation. 18. Side Reaction- side reaction is a chemical reaction that occurs at the same time as the actual main reaction, but to a lesser extent. 66. Subscript It is a small number written below and to the right of a chemical symbol. It tells you how many atoms of that element are in a molecule. 67. Coefficient It is a number written in front of a chemical formula. It tells you how many of those molecules or atoms are involved in a reaction. 68. One mole of reac- Defined as occurring when the number of moles given by tion the. coefficients in your balanced equation react. 69. Activation Ener- The minimum energy required for a reaction to occur. gy 7 / 7 7 70. Catalysis The increase in the rate of a chemical reaction by lowering its activation energy. 71. Transition State An intermediate state during a chemical reaction that has a higher energy than the reactants or the products. 72. Maxwell-Boltz- A probability distribution used for describing the speeds of mann various particles within a stationary container at a specific Distribution temperature the distribution is often represented with a graph, with the y axis defined as the number of molecules and the x axis defined as the speed. 73. Concentration Refers specifically t o the amount of reactants or the catalyst itself present in a reaction mixture per unit volume. 74. Catalyst A substance that speeds up a chemical reaction without being permanently changed itself. 75. Temperature Refers to the degree of hotness or coldness of an object. It's a way to quantify how much thermal energy, or heat, is present in something 76. Particle Size Refers to the dimension of individual particles that make up a substance. It's a crucial factor influencing various aspects of chemical reactions and material properties. 77. Enzymes Are molecules that act as biological catalysts. They speed up chemical reaction in living organism without being use of themselves. Are essential for life because they allow cells to carry out many of the chemical reactions that are necessary for growth, repair, and other functions.
