  1. displacement- the chemical reactions in which one component each of both the reacting molecules is exchanged to form the products
  2. reaction- a process that involves rearrangement of the molecular or ionic structure of a substance, as opposed to a change in physical form or a nuclear reaction.
  3. equation- An expression of equality between two formulas in mathematics
  4. of conservation mass- the atoms of an object cannot be created or destroyed, but can be moved around and be changed into different particles.
  5. a chemical reaction in which an acid and a base react quantitatively with each other. In a reaction in water, neutralization results in there being no excess of hydrogen or hydroxide ions present in solution.
  6. scale- is a measure of how acidic or basic a substance is
  7. Chemical Equation- represents a chemical reaction using coefficients (numbers in front of reactants and products) that tell how much of the reactants are used and how much of the products are made
  8. displacement reaction- A single-displacement reaction, also named single-replacement reaction, is a type of oxidation-reduction chemical reaction when an element or ion moves out of one compound and into another - that is, one element is replaced by another in a compound.
  9. a compound that tastes sour, corrodes metals and tissue, and turns blue litmus paper red.
Down
  1. make (a liquid) thinner or weaker by adding water or another solvent to it.
  2. any substance that in water solution is slippery to the touch, tastes bitter, changes the colour of indicators (e.g., turns red litmus paper blue)
  3. reaction- analysis or breakdown is the separation of a chemical compound into elements or simpler compounds. It is sometimes defined as the exact opposite of a chemical synthesis.
  4. reaction- is a reaction where two or more elements or compounds
  5. indicator- a substance that changes colour when added to an acid or base
  6. non-toxic base that is used to neutralize stomach acid; relieves the pain of excess stomach acid
  7. reactant-They are the things that are present at the starting point. By convention, the chemical symbols for the reactants are written on the left hand side of the chemical reaction equation. The products are the substances that are formed during the chemical change
  8. formula- a set of chemical symbols showing the elements present in a compound and their relative proportions, and in some cases the structure of the compound.
  9. an atom or molecule with a net electric charge due to the loss or gain of one or more electrons.
