1568249806 | Electronegativity | The attraction of a particular atom for the electrons of a covalent bond. | 1 | |
1568249807 | Nonpolar Covalent Bond | An attraction that forms when the electrons are shared equally between atoms that have the same electronegativity. | 2 | |
1568249808 | Polar Covalent Bond | An attraction that forms between atoms with different electronegativities so that the electrons of the bond are not shared equally. | 3 | |
1568249809 | Hydrogen Bond | The attraction between a hydrogen and an electronegative atom. | 4 | |
1568249810 | Van der Waals Interaction | Weak attraction that occurs between molecules in close proximity to each other that have ever-changing regions of positive and negative charge. | 5 | |
1568249811 | Cohesion | The linking together of like molecules, often by hydrogen bonding. | 6 | |
1568249812 | Adhesion | The clinging of one substance to another, often by hydrogen bonding. | 7 | |
1568249813 | Specific Heat | The amount of heat that must be absorbed or lost for 1 g of that substance to change its temperature by 1 degree Celsius. | 8 | |
1568249814 | Heat of Vaporization | The quantity of heat a liquid must absorb for 1 g of it to be converted from the liquid to the gaseous state. | 9 | |
1568249815 | Evaporative Cooling | The process in which the surface of an object becomes cooler during evaporation, a result of the molecules with the greatest kinetic energy changing from the liquid to the gaseous state. | 10 | |
1568249816 | Acid | A substance that increases the hydrogen ion concentration of a solution. | 11 | |
1568249817 | Base | A substance that reduces the hydrogen ion concentration of a solution. | 12 | |
1568249818 | pH | A figure expressing the acidity or alkalinity of a solution on a logarithmic scale | 13 | |
1568249819 | Buffer | A substance that minimizes changes in the concentrations of hydrogen or hydroxide ions in a solution. | 14 | |
1568249820 | Organic Chemistry | The study of compounds containing carbon. | 15 | |
1568249821 | Hydrocarbons | Organic molecules consisting of only carbon and hydrogen. | 16 | |
1568249822 | Functional Groups | A specific configuration of atoms commonly attache to the carbon skeletons of organic molecules and involved in chemical reactions. | 17 | |
1568249823 | Hydroxyl | A functional group that commonly indicates the substance is an alcohol. | 18 | |
1568249824 | Carbonyl | A functional group that commonly indicates the substances is a carbohydrate. | 19 | |
1568249825 | Carboxyl | A functional group that commonly indicates the substance is an acid. | 20 | |
1568249826 | Amino | A functional group that commonly indicates the substance is a base. | 21 | |
1568249827 | Sulfhydryl | A functional group that helps to stabilize protein structure. | 22 | |
1568249828 | Phosphate | A functional group that confers on a molecule the ability to react, releasing energy. | 23 | |
1568249829 | Methyl | A functional group that commonly affects the expression of genes. | 24 |
