Write word & balanced chemcial equations for Solid calcium reacts with solid sulfur to produce solid calcium sulfideĬalcium + sulfur -> calcium sulfide 8Ca(s) + Sg(s) -> 8CaS(s) Teh temperature at which reaction is carried out in this case 0 degrees Cįormula of catalyst, in this case manganese dioxide, used to alter teh rate of the reaction Preasure at which reaction is carried out exceeds normal atmospheric pressureĪn arrow with 0 degrees C above it indicates Preassure at which reaction is carried out in this case 2 atmĪn arrow with the word pressure written above it indicates Writing two arrows pointing in opposite directionsĪ reactant or product in a solid state also used to indicate a precipitateĪ reactant or product in an aqueous solution (dissolved in water) The word heat symbolized by a Greek capital deltaĪ substance that changes the rate of a chemical reaction but can be recovered unchangedĪ chemical reaction in which the products re-form the orignal reactants. To show the formation of a Precipitate during a reaction in solution The relative amounts of reactants and products represented in the equation must be adjusted so that the numbers and types of atoms are the same on both sides of the equation is calledĬounting atoms of elements that are combined with atoms of other elements and that appear only once on each side of the equationĬhanging the subscripts of a chemical formula changes the The corresponding substnce is in the gaseous state In a formula equation the g in parentheses after each formula indicates

Represents the reactants and products of a chemical reaction by their symbols or formulas. React to yield or yield (also produce or form The first steps in writing in a chemical equation isĪ word equation has only what type of meaning If no coefficiet is written, the coefficient is assumed to beĪn equation in which the reactants and products in a chemical reaction are represented by words The relative number of moles of the substance Placing a coefficient in front of a formula specifies The law of conservation of mass must be satisfied.Ī small whole number that appears in front of a formula in a chemical equation. The equation must contain the correct formulas for the reactants and products.ģ. The equation must represent known facts.Ģ. What aides you in writing and reading chemical equations correctlyġ. True or False: Heat or light by itself is not necessarily a sign of a chemical change because many physical changes also involve either heat or lightĪ solid that is produced as a result of a chemical reaction in solution and that separates from teh solution Represents with symbols and formulas the identities and relative molecular or molar amounts of the reactants and products in a chemical reaction.Ĭhanges which usually indicate that a chemical reaction has occurred.

The total mass of reactants must equal the total mass of products for any given chemical reactions In any chemcial reaction, the resulting substances are known as In any chemical reaction, the original substances are known as The process by which one or more substances are changed into one or more different substances.
