Discovering Design with Chemistry Chapter 8 part 1

Repeating an experiment again and again or having others repeat it again and again is called:

The Author of the books asks, Is there something wrong with stoichiometry? What is the answer?

Which formula shows the actual number of each element in a compound?

What decreases when combining 50 mL vinegar with 2 grams sodium bicarbonate without containment?

What formula shows the simplest ratio of elements present in a compound?

What is the empirical formula of C₈H₁₂O₄?

When calculating chemistry, a person should be sure to check significant numbers at each step in the calculation.

Some compounds are both molecular and empirical formulas.

Experimental error is unavoidable.

Stoichiometry says 10g of product should be made. An experiment is run 4xs. Which has the most experimental error?

Experimental error is a real thing.

Things that work well on paper in our calculations always work out just as well in our experiments.

50g Ti burned in excess O. It produces a mass of 83.3g. What is the empirical formula?

What kind of formula is C₈H₁₂O₄?

In this course, calculating percent yield is an important skill to have.

The difference between a quantity's measured value and its true value is . . .
