Front

What is the balanced equation for the reaction of NaF and Br2?

Back

The balanced equation is 2 NaF + 1 Br2 -> 2 NaBr + 1 F2.

Front

How many moles of NO are produced from 1 mole of O2 in the reaction 4NH3 + 5O2 -> 4NO + 6H2O?

Back

0.8 moles of NO are produced when 1 mole of O2 is completely consumed.

Front

What is the definition of a mole in chemistry?

Back

A mole is a unit of measurement that represents 6.02 x 10^23 particles of a substance.

Front

How do you convert moles to grams?

Back

To convert moles to grams, multiply the number of moles by the molar mass of the substance (grams/mole).

Front

What is the molar mass of water (H2O)?

Back

The molar mass of water is approximately 18.02 g/mol.

Front

What is the significance of balancing chemical equations?

Back

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

Front

How do you determine the limiting reactant in a chemical reaction?

Back

The limiting reactant is the substance that is completely consumed first, limiting the amount of product formed.
