| For a classical name what does (-ous) mean? | It is the cation with the smaller charge |
| For a classical name what does the (-ic) mean? | It is the cation with a larger charge |
| What do the names of polyatomic anions end in? | -ite or -ate |
| The -ite indicates what in a polyatomic chemical formula? | it has one less oxygen atom than the -ate ending |
| All anions with the names ending in what, contain oxygen atoms? | -ite or -ate |
| What did the French chemist Antoine-Laurent Lavoisier determine? | Determined the composition of many compounds in his experiments to show how chemical compounds form. He developed a systematic method for naming chemical compounds. |
| What is an acid consisted of? | An anion combined with as many hydrogen ions needed to make the molecule electrically neutral. |
| What is the general form of chemical formulas for acids? | HnX |
| What does the general form of chemical formulas of acids stand for? | H- hydrogen, n is the subscript showing the number of hydrogen atoms that are combined with the anion and X is a mono or polyatomic anion |
| How is the law of definite proportions consistent with Dalton's atomic theory? | Dalton postulated that atoms combine in simple whole-number ratios. |
