Data is presented in tables and all data is recorded Each data table is clearly labeled/titled All data has the correct number of significant digits All data has the correct units All calculations are clearly labeled/titled Equations are written in words or clearly recognized symbols for all calculations (for stoichiometry – make sure to label each factor with a unit and identify substance) Show all work for each calculation (if there are repeat calculations for several trials you may do one sample calculation and report your answer for the other calucations…make sure to label each trial) All answers must have the correct number of significant figures All answers must have the correct units Correct calculation for CuSO4 experimental Correct calculation for CuSO4 theoretical Correct calculation for percent yield Correct calculation and formula for the empirical formula of the copper sulfate hydrate Correct calculation for experimental molar mass of copper sulfate hydrate Correct calculations for the experimental and theoretical percent of Cu2+ in the hydrate Correct calculations for the experimental and theoretical percent of SO42- in the hydrate Correct calculations for the experimental and theoretical percent H2O in the hydrate analysis Written in paragraph form – correct use of the third person, spelling and grammar Each analysis includes experimental and theoretical data for support (analysis of hydrate percent yield, percent Cu2+ in hydrate, percent SO42- in hydrate, percent of H2O in hydrate) Each analysis includes a plausible error inherent in the procedure that coincides with the data. Thoroughly explain the causal relationship between the proposed error and the data (analysis of hydrate percent yield, percent Cu2+ in hydrate, percent SO42- in hydrate, percent of H2O in hydrate) Thoughts are organized coherently
