| chemical interactions | Answer |
|---|---|
| matter | has mass and takes up space |
| chemistry | the study of the properties of matter and how matter changes |
| element | a substance that cannot be broken down into any other substances by chemical or physical means |
| compound | a substance made of two of more elements chemically combined in a specific ration, or proportion |
| mixture | two or more substances that are mixed together but not chemically combined |
| chemical change | a change in matter that produces a new substance |
| physical change | a change that alter the appearance of a material but does not make the material into another substance |
| synthesis | when two or more substances combine to make a more complex substance |
| decomposition | when compounds are broken down into simpler substances |
| replacement | when one element replaces another in a compound |
| valence electron | the electrons that are the furthest away from the nucleus of an atom and are involved in chemical reaction |
| factors that influence a chemical reaction | temperature, catalysts, concentration, surface area, inhibitors |
| covalent bond | electrons are shared |
| ionic bond | electrons are given up and the atoms are attracted because they have opposite charges |
| solution | a well mixed mixture |
| suspension | a mixture in which the particles can be seen easily and filtered out |
| colloid | whip cream, shaving cream |
| solvent | does the dissolving |
| solute | is dissolved |
| increase in freezing point | solute is added |
| water | universal solvent |
| solute | decreases freezing point |
| base | bitter taste, feel slippery, OH- |
| acid | sour taste, react with metals, H+ |
| enzymes | speed up chemical reactions in the body |
| atomic number | number of protons in a atom |
| amino acid | monomer of proteins |
| glucose, fructose | sugars |
| isotopes | same element with different number of neutrons |
| surface tension | created because water molecules are polar and stick together |
| nucleic acids | dna, rna |
| proteins | made of amino acids |
| polysaccharides (starches) | made of sugars |
| lipids | fats, oils, waxes |
| use of sugar | energy |
| use of protein | serve as to build tissue, control speed of reactions (enzymes), transports substances into and out of the cell, and help fight disease. |
| uses of lipids | components of the cell membranes, energy use |
