Protons and Neutrons are made up of even smaller particles, called what?

Quirks

Unit 1 Continued

100

The smallest particles that make up matter while still maintaining their chemical and physical properties:

atoms

200

When two or more atoms are bonded together, it makes up a:

Molecule

300

When a solid turns directly to a liquid, it is called:

Sublimation

400

Explain what happens at absolute zero

all energy is gone and there is no kinetic energy in the atoms/molecules

500

Less Pressure

Unit 2

100

Reactants

200

Name 4 of the 5 signs of chemical change that we discussed in class (and demonstrated in labs)

Formation of gas, Light production, heat production, color change, formation of a precipitate

300

Would burning methane be a chemical or physical change? Would this be endothermic or exothermic?

Chemical, Exothermic

400

C₅H₁₂ + 7O₂ --->  4 CO₂ + 5 H₂O

Is this chemical reaction balanced?

No

500

2(H₂SO₄)₃

How many Oxygen are represented in the formula above?

Unit 3

100

What is the name of the process plants use to create glucose

Photosynthesis

200

What two things are created via photosynthesis

O_{2 and glucose}

300

Explain why photosynthesis is important (What do pants create with photosynthesis, and what do they use that to make)

They make glucose, which in turn is used to create ATP for energy

400

 Explain Commensalism and give an example

One organism benefits, one is unaffected

500

Explain the difference between a decomposer and a scavenger

Scavengers metabolize food similar to the way predators do, while decomposers break them down at a molecular level
