mass to mass stoichiometry

what is the first step in mass to mass stoichiometry?

• balance the chemical equation

• find the excess reactant

• find the mean, median and, mode

• 23

what index of measurement is used in mass to mass stoichiometry?

• mol

• kilometeres

• fries per cheeseburger

• grams

How do you balance a chemical equation?

• make sure chemicals from both sides are equal

• Use random numbers as your coefficients.

Balance the chemical equation: Al + O₂ = Al₂O₃

• 2Al + 2O₂ + 2Al₂O₃

• 4Al + 3O₂ + 2Al₂O₃

• 3Al + 2O₂ + 3Al₂O₃

• 2Al + 3O₂ + 4Al₂O₃

Balance the equation: H₂ + O₂ —> H₂O

• 2H₂ + O₂ —> 2H₂O

• H₂ + O₂ —> 2H₂O

• 3H₂ + 2O₂ —> 2H₂O

• median

What is mass to mass stoichiometry used for?

• To find the amount of grams produced a certain chemical reaction..

• To find the molar mass of an element

• To find the amount of grams produced from a physical reaction.

What “thing” are you solving for when finding the “grams” used in the equation

• Molar mass of the given.

• Atomic number of the given.

• Kilometers per hour of the given.

Mole Ratios used for conversions are derived from:

• The molar mass of the reactants in the balanced chemical equation

• the coefficients of the balanced chemical equation

• the subscripts of the products in the balanced chemical equation
