- Q1In order to perform a stoichiometry calculation you must always havea periodic tablethe molar mass for every compound and elementa balanced equationan electronic balance30s
- Q2To find the molar mass of an element or compound you needthe molar ratioa periodic tablea balancea balanced equation30s
- Q3What is stoichiometry?The quantitative relationships between amounts of reactants used and products formed by a chemical reactionThe relationship between the periodic table and the molar massThe relationship between you and your best friendThe relationship between moles of each substance in a reaction30s
- Q4The coefficients in a chemical equation tell youthe percent compositionthe molar ratiothe amount of productthe molar mass30s
- Q5Stoichiometry is based on theAvagadro's numberLaw of Conservation of Mattermolar massconversons30s
- Q6What is a limiting reactant?is the reactant the is "left over"is always oxygendoes not reactthe reactant that "runs out' first30s
- Q7What is an excess reactant?The reactant that is "left over".the reactant that "runs out" firstthe reactant that reacts lastthe reactant that dos not react30s
- Q8The limiting reactant determineshow much excess reactant is usedhow much product is madeall of thesehow much excess reactant remains30s
- Q9You want to make hamburgers for a cookout. You have 12 burger patties and 10 hamburger buns. How many complete hamburgers can you make and what is you limiting ingredient.10 hamburgers, burger patties12 hamburgers, burger patties12 hamburgers, hamburger buns10 hamburgers, hamburger buns30s
- Q10When calculating percent yield, the theoretical yield iswhat you got in the labthe percentagethe total of all the reactantsWhat you were supposed to get according the math/stoichiometry30s
- Q11When calculating percent yield the actual amount would bethe measurement you got in labthe amount you got using stoichiometrythe molar massthe percentage30s
- Q12What is the equation of percent yield?part/whole X 100actual yield/ theoretical yield X 100theoretical yield/actual yield X 100whole/part X 10030s
- Q13
When setting up a stoichiometry problem, how do know what number to put in front of "g" on the right hand side of the equation?
Use the molar mass of the element/compound X the coefficient from the balanced equation
