TRUE!

300

What are the 4 states of matter included in a chemical equation? 

Solid (s), Liquid (l), Gas (g), and Aqueous (aq)

300

When balancing equations, do we change the coefficients or the subscripts in a chemical equation?

coefficients!!

300

How can you easily identify a combustion reaction?

A hydrocarbon fuel combining with oxygen and producing water and carbon dioxide. 

300

400

Given the following description, what are the states of matter for each compound/element.

Solid potassium reacts with water to form hydrogen gas and potassium hydroxide dissolved in water.

Potassium = solid

Water = liquid

Hydrogen = gas

Potassium hydroxide = aqueous

400

What is missing from this chemical equation to make it complete?

NaCl(l) 🡪    Na(l) +   Cl2 (g)

It's not balanced!!

2NaCl(l) 🡪  2Na(l) +   Cl2 (g)

400

What's the difference between a single replacement and double replacement reaction? 

Single Replacement:

A + BC --> AC + B

Double Replacement:

400

Does sound travel faster in the air or in water?

Water!

500

What's the difference between aqueous and liquid?

"Aqueous" refers specifically to a substance dissolved in water, meaning it's a solution where water is the solvent, while "liquid" simply describes a substance in its liquid state, which could be any liquid, not necessarily water
