Flammability is what type of property?
What is a chemical property?
This particle has a positive charge.
What is a proton?
These are the starting materials used at the beginning of a chemical reaction.
What are Reactants?
Ionic compounds are formed when these two general types of elements combine.
What are a Metal and a Non-metal?
This symbol means a material can catch fire easily.
What is flammable?

What is the number of protons?
According to this law, the total mass of the products is always equal to the total mass of the reactants.
What is the Law of Conservation of Mass?
This is the correct IUPAC name for the molecular compound N2O4
What is Dinitrogen Tetroxide?
This symbol indicates a compressed gas stored under pressure.
What is compressed gas?
If a substance can be flattened into thin sheets, like aluminum foil, it is said to have this property.
What is Malleability?
Thomson’s model is called the __________ model.
What is the raisin bun (plum pudding) model?
In this type of system, no material can enter or escape, making it easier to prove that mass is conserved.
What is a Closed System?
This is the correct IUPAC name for the ionic compound FeCl3, which must include a Roman numeral because iron is a multivalent metal.
What is Iron (III) Chloride?
If a chemical has the skull and crossbones symbol, it indicates this type of hazard.
What is acute toxicity (poison)?
Sand and water together form what type of mixture?
What is a heterogeneous mixture?
Dalton’s model is often compared to this object.

This substance speeds up a chemical reaction without being consumed or used up itself.
What is a Catalyst?
This is the correct chemical formula for Copper (II) Sulfate, which contains the polyatomic ion SO42-.
What is CuSO4?
While the "Flame" symbol is for general fire hazards, this symbol featuring a flame over a circle (the letter 'O') is used for these specific materials that provide oxygen to a fire.
What are Oxidizing Materials?
This cloudy mixture is one that dosen't split
what is Colloid?
In his Gold Foil experiment, this scientist discovered that the atom is mostly empty space with a dense, positive nucleus.
Who is Ernest Rutherford?
This type of reaction involves one ionic compound and a metal, where the metal replaces an ion to form a new compound.
What is a Single Replacement Reaction?
This is the IUPAC name for CaCo3, a compound containing a metal and a polyatomic ion commonly found in limestone and eggshells.
