How do you calculate the molar mass of a compound?

Back

To calculate the molar mass, sum the atomic masses of all atoms in the compound's formula.

What is the balanced equation for the reaction of PCl5 with H2O?

Back

The balanced equation is: PCl5 + 4 H2O → 5 HCl + H3PO4.

What are the four main types of chemical reactions?

Back

The four main types of chemical reactions are synthesis, decomposition, single displacement, and double displacement.

Front

What is a decomposition reaction?

Back

A decomposition reaction is a type of chemical reaction where a single compound breaks down into two or more simpler products.

Front

What is a single displacement reaction?

Back

A single displacement reaction is a type of chemical reaction where one element replaces another element in a compound.

Front

What is a double displacement reaction?

Back

A double displacement reaction is a type of chemical reaction where two compounds exchange ions or bonds to form two new compounds.

Front

What is the definition of molar mass?

Back

Molar mass is the mass of one mole of a substance, typically expressed in grams per mole (g/mol).

Front

What is the significance of balancing chemical equations?

Back

Balancing chemical equations ensures that the law of conservation of mass is obeyed, meaning the number of atoms of each element is the same on both sides of the equation.
