pH & Water Chemistry

4. forms when electrons are shared between atoms
10. (chemicals being created) are written on the right side of a chemical equation.
11. mixtures of water and non-dissolved materials
12. found in the nucleus with no charge
13. a solution that contains a higher concentration of H+ ions than pure water and has a pH value below 7
15. a substance formed by the chemical combination of two or more elements in definite proportions
16. water slowly heats and resists temperature change
20. Water is attracted to other molecules/substances
21. is a measure of the concentration of H+ ions in a solution

1. formed when one or more electrons are transferred from one atom to another
2. When molecules are close together, a slight attraction can form between the oppositely charged regions of nearby molecules
3. found circling the nucleus with a positive charge
5. (chemicals being combined) are written on the left side of a chemical equation.
6. material composed of two or more elements or compounds that are physically mixed together, but not chemically combined
7. a pure substance that consists entirely of one type of atom
8. weak acids or bases that react with strong acids and bases to keep pHs within a certain range
9. a mixture where a solid is dissolved into a liquid.
10. found in the nucleus with a positive charge
13. the smallest particles of an element that still have all the properties of an element
14. Water is attracted to water (makes water “sticky!!”).
17. when the electrons Between atoms in a molecule are shared unequally
18. atoms of the same element that have the same number of protons but a different number of neutrons
19. a solution that contains a lower concentration of H+ ions than pure water and has a pH value above 7
