This term refers to the sum of the atomic masses of all the atoms in one mole of a compound.

What is Molar Mass?

200

Chemical equations must be balanced to satisfy this fundamental law, stating matter cannot be created or destroyed.

What is the Law of Conservation of Mass?

200

Like two people deciding to go on a date and becoming a "couple," this reaction involves two or more substances combining to form one single product.

What is Synthesis

200

This small subscript letter in parentheses indicates that a substance is a gas.

What is (g)?

200

When an HCl reacts with a NaOH (Neutralization), the products are always a salt (NaCl) and this common liquid.

What is water (H2O)?

400

Calculated by adding one Carbon and two Oxygens, this is the molar mass of CO2 (rounded to the nearest whole number).

What is 44 g/mol?

400

This is the coefficient needed for O2 to balance:

CH4 + H2O → CO2 + 2H2O.

What is 2?

400

The ultimate "break-up": In this reaction, a single complex compound simplifies by splitting into two or more smaller products.

What is Decomposition?

400

This is the chemical formula for the common substance known as Sodium Chloride.

What is NaCl?

400

If you start with Li + NaCl, the Lithium will kick out the Sodium, resulting in these two products.

What are LiCl and Na?

600

To find the number of particles in a mole, you use this famous number: 6.022 x 1023.

What is Avogadro’s Number?

600

To balance the equation for making ammonia 

(N2 + H2 → NH3), these three coefficients are needed in order.

What are 1, 3, and 2?

600

Think of this as "stealing your friend's date." One lone element replaces another element that was already part of a compound.

What is Single Replacement?

600

Translated to "Chem-ish," the phrase "Magnesium reacts with Chlorine to form Magnesium Chloride" looks like this.

What is Mg + Cl2 → MgCl2?

600

In a synthesis reaction between Calcium (Ca) and Nitrogen (N2), this is the only possible product.

What is calcium nitride? (Ca3N2)

800

If you have 2 moles of Water, you have approximately this many grams.

What is 36 grams?

800

DAILY DOUBLE: In the balanced equation 2H2 + O2 → 2H2O, this is the total sum of all coefficients (including the invisible 1).

What is 5?

800

This "wife swap" or "partner trade" occurs when the cations and anions of two different compounds switch places to form two entirely new compounds.

What is Double Replacement?

800

In a chemical word equation, these substances are written on the left side of the arrow.

What are reactants?

800

If Calcium Carbonate (CaCO3) undergoes double replacement with Silver Nitrate (AgNO3), it typically produces Calcium Nitrate (Ca(NO3)2) and this compound.

What is Silver Carbonate? (Ag2CO3)

1000

This number is used for the mass of a single atom, and it is numerically identical to grams per mole.

Atomic mass

1000

Balance this: Fe + O2 → Fe2O3.

What is 4Fe + 3O2 → 2Fe2O3?

1000

This reaction is the "toxic flame" of chemistry: a substance reacts with Oxygen gas, usually releasing energy in the form of light and heat.

What is Combustion?

1000

Using Roman Numerals for charge, this is the correct formula for the product "Iron(III) Oxide."

What is Fe2O3?

1000

In a double replacement reaction between CsNO3 and (NH4)3PO4 , these products are formed.

What are Cs3PO4 and NH4NO3?
