Intensive: yellow
Extensive: 5g, 10 cm, etc.
300
Mixing corn starch with water to make goop. P or C? AND EXPLAIN.
Physical - you are only changing the texture, that is not a sign of a chemical change.

What is one unit for the density of a liquid?
g/mL
400
Is density an intensive or extensive property? Explain.
Intensive. It does not change if the size or amount changes.
400
Mowing the lawn. Intensive, extensive or chemical? AND EXPLAIN
Extensive - you are only changing the size of the pieces of grass. There is nothing new created.

You have 40 seconds to give 4 intensive and 3 extensive (descriptive, not exact) properties of the SMART BOARD
In lab we added vinegar to baking soda and observed bubbles, a acidic odor, a liquid substance, fizzing sound and a colder temperature.
What are the 6 signs of a chemical change and how many signs of a chemical change occurred above?
1. color change 2. odor change
3. bubbles/gas 4. sound/light
5. temp. change 6. cannot be reversed'
3, 4, 5 are correct. 2 is not, the smell was there beforehand.

If the density of soy sauce is 1.5g/mL and I have 600g of it. What is the volume of the soy sauce?
400mL, 600/400 = 1.5
500
Describe in detail how you would find the density of a cup of soy sauce .
What is find the volume by putting it into a graduated cylinder. Then find the mass by placing the cylinder in a scale and subtracting the mass of the empty cylinder. Then divide the mass by the volume.
