(a)
Interpretation:
A balanced chemical equation for the reaction between
Concept introduction:
In a balanced chemical equation, the total mass of reactants and products are equal in a balanced chemical equation, thus, it obeyed the law of conservation of mass. Also, the amount of substances in a balanced
Following are the steps to determine the moles of a chemical substance when the moles of another chemical substance present in the chemical reaction are given,
Step 1: Write the names and molecular formulas of the substances involved in the chemical reaction.
Step 2: Write the balanced chemical equation by using
Step 3: Determine the molar ratio from the balanced chemical reaction between the chemical substance whose amount is given and the chemical substance whose amount is to be calculated.
Step 4: Use the molar ratio and the given amount to calculate the unknown amount of the other substance.
(b)
Interpretation:
A balanced chemical equation for the reaction between liquid disilicon hexachloride reacts with water to form solid silicon dioxide, hydrogen chloride gas and hydrogen gas is to be written.
Concept introduction:
In a balanced chemical equation, the total mass of reactants and products are equal in a balanced chemical equation, thus, it obeyed the law of conservation of mass. Also, the amount of substances in a balanced chemical reaction are stoichiometrically equivalent to each other.
Following are the steps to determine the moles of a chemical substance when the moles of another chemical substance present in the chemical reaction are given,
Step 1: Write the names and molecular formulas of the substances involved in the chemical reaction.
Step 2: Write the balanced chemical equation by using stoichiometric coefficients.
Step 3: Determine the molar ratio from the balanced chemical reaction between the chemical substance whose amount is given and the chemical substance whose amount is to be calculated.
Step 4: Use the molar ratio and the given amount to calculate the unknown amount of the other substance.
(c)
Interpretation:
A balanced chemical equation for the reaction of nitrogen dioxide bubbled into the water to form nitric acid solution and nitrogen monoxide gas is to be written.
