Chemical Reaction: Formation of Phosphoric Acid
How many grams of phosphoric acid must form?
When diphosphorus pentoxide and water combine to form phosphoric acid, how many grams of phosphoric acid must form if 23.1 grams of diphosphorus pentoxide and 8.8 grams of water are used?
Answer:
When diphosphorus pentoxide and water combine, they form phosphoric acid. The total mass of the reactants is equal to the total mass of the products in line with the law of conservation of mass. Therefore, given 23.1g of diphosphorus pentoxide and 8.8g of water, 31.9g of phosphoric acid must form.
When diphosphorus pentoxide and water combine under certain conditions, they form phosphoric acid in a chemical reaction. This reaction follows the law of conservation of mass, which states that mass is neither created nor destroyed in a chemical reaction. According to this principle, the total mass of the reactants (diphosphorus pentoxide and water) is equal to the total mass of the products (phosphoric acid).
Thus, the mass of phosphoric acid formed must be equal to the sum of the mass of the reactants. Given 23.1 grams of diphosphorus pentoxide and 8.8 grams of water, this sums up to 23.1 g (reactant) + 8.8 g (reactant) = 31.9 g. Therefore, 31.9 grams of phosphoric acid must form.
