SCH3U0 Writing Chemical Formula FOR DUMMIES Name: _____________ Your task is to create a dichotomous key to help students WRITE FORMULAE for all the different types of compounds that we have learnt this unit. Your audience will be students beginning their grade ten who have minimal knowledge on writing chemical formulas. They are able to: • Read the periodic table and identify metals‚ metalloids‚ and non‐metals • Identify polyatomic‚ but don’t have them memorized • Read the oxidation states (charges) on the periodic table

Dasmariñas Dasmariñas‚ Cavite Philippines ABSTRACT This experiment was performed to learn the technique of acid-base titration and to compare the efficiency of commercially available antacids by looking at their weight of HCl and weight of antacid values. The analysis of antacid tablets was highlighted in this experiment. The efficiency of antacid tablets was determined and compared when the number of grams of HCl can be neutralized by 1 gram of the tablet was found. First‚ the two antacid tablets
