- Find the reaction stoichiometry and use it to predict expected mass of products.
Consider the reaction: CH2O→CO2HO - Find the reaction stoichiometry and use it to predict the mass of chemicals used in a reaction.
Consider the reaction: HCINaOH→NaClHO - Find the reaction stoichiometry and use it to predict the mass of chemicals used and produced in a reaction.
Consider the reaction: 2CH7O→4CO6HO- How many moles of O would react with 1 mole of CH?
- If 15 moles of HO were produced in this experiment, how many moles of CH were used?
- What is the mass of this amount of CH used?
- A total of 0.19 mol of reactants and products combined were involved in this reaction. What is the number of moles of HO produced?
- Find the percentage composition by mass of chemical compounds and use percentage composition to find empirical formula.
