1. The yeast plays the role of a catalyst, assisting in expediting the break down
of H2O2 into 2H2O and O2. Unlike the sodium bicarbonate that combines with
Chlorine to make NaCl, the yeast is not fully used up. Also, it does not

Lab # 1 Questions 1.
Looking at the class results, can you make any generalizations? For example, do potato chips have more or less fat than tortilla chips? Looking at the other results from our classmates on the data sheet, it can be
Lab #7 Questions To Be Answered: 1. The tetrahedral shape is one of the most fundamental shapes in chemical compounds. How would you describe it in words to someone ho has never seen it? Basically it is one atom surrounded by four others, that are pl
