\$400 Answer from Unit 3: - Liquid and gas

\$500 Question from Unit 3: 1. Give the pH scale 2. Provide an example of an acid, a base, and a neutral substance

\$500 Answer from Unit 3: 1. 0-14 2. Acid: coffee, lemon 3. Basic: cleaners, bleach 4. Neutral: water

\$100 Question from Unit 4: What is the name of the following compound: CaCl 2 AND what is the ratio of Ca to Cl atoms?

\$100 Answer from Unit 4: Calcium Chloride 1 Ca : 2 Cl

\$200 Question from Unit 4: Write the correct chemical formula for a compound made up of Ba and F.

\$200 Answer from Unit 4: Ba +2 F -1 = BaF 2

\$500 Answer from Unit 4: A precipitate!!

\$100 Question from Unit 5: A merry-go-round horse moves at a constant speed but at a changing ____________.

\$100 Answer from Unit 5: Velocity.. Constantly changing directions!

\$200 Question from Unit 5: According to Newtons 2 nd Law… For any object, the greater the force that's applied to it, the greater its __________ will be.

\$200 Answer from Unit 5: Acceleration! F = ma

\$300 Question from Unit 5: When you exert force to stand up, an equal and opposite force is exerted by the floor. These forces are called ________ - ___________ forces. Which of Newtons Law does this obey?

\$300 Answer from Unit 5: Action-Reaction Newtons 3 rd Law!
