100

What is the measure of how acidic or basic a solution is?

pH

100

How many elements are present in the following chemical formula: AlBr.

2

200

Name three signs that a chemical reaction has taken place. 

Apperance of bubbles, formation of a precipitate, change in color, change in odor

200

What is the difference between a saturated and an unsaturated solution?

A saturated solution contains the most solute that can be completely dissolved in a given amount of solvent. An unsaturated solution can still dissolve more solute in the solvent. 

200

Name three properties of acids. 

Taste sour, increase hydronium in water, corrosive, turn blue litmus paper red. 

200
Substances with a pH of 7 are said to be?

Neutral

200

Name two products of a neutralization reaction. 

Salt and water

300

How many molecules of oxygen are present in 4CO2

4

What is a name for a solution that has a small amount of solute in a given amount of solvent? 

Dilute 

300

What is the name for a reaction between an acid and bases in a water solution?

Neuralization reaction

300

The burning of fossil fuels releases sulfur oxides and nitrogen oxides, which combine with water in the air to produce sulfuric acid and nitric acid. What can this cause?

Acid Rain

300

What is the value range for bases on the pH scale? Be specific! 

7.1 - 14

400

What does the law of conservation of mass state?

Matter is neither created nor destroyed in chemical changes. The left side of a chemical equation must show the same number and kinds of atoms as the right side. 

400

Explain what a suspension is. 

Large particles are distributed in a gas or a liquid, they do not dissolve so they block light, they can be separated by a filter. 

400

Chemicals that are caustic and slippery are called what?

Bases

Name three things that can affect the rate of a chemical reaction. 

Concentration, surface area, temperature, and presence of a catalyst.

500

A chemical reaction that requires an input of energy is called?

An endothermic reaction. 

500

Name three factors that can affect solubility. 

Temperature, surface area, motion

500

How do strong acids and bases behave differently than weak acids and bases?

Strong acids and bases break apart completely in water and weak acids and bases do not. Weak acids and bases remain mostly intact.

Milk - 6.5

Ammonia - 12
