Front

What is the formula for calculating the mass of sodium nitrate formed in a reaction?

Back

Mass of sodium nitrate = Total mass of reactants - Mass of products.

Front

What is the nuclear symbol for lithium-6?

Back

The nuclear symbol for lithium-6 is 6Li.

Front

What is the law of conservation of mass?

Back

The law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction.

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.

Front

What is the balanced equation for the reaction between silver nitrate and sodium chloride?

Back

AgNO3 + NaCl → AgCl + NaNO3.

Front

What is the significance of molar mass in chemistry?

Back

Molar mass allows chemists to convert between grams and moles, facilitating stoichiometric calculations.

Front

How do you find the mass of a product formed in a chemical reaction?

Back

Use the balanced equation and the masses of the reactants to calculate the mass of the product.
