Mass Changes When a Reactant or a Product is a Gas January 2022

Explain any observed changes in mass in nonenclosed systems during a chemical reaction Recall how to balance chemical equations. Identify changes in mass in a nonenclosed system. Apply the particle model to explain changes in mass in non-enclosed systems.

Mass Changes When a Reactant or a Product is a Gas January 2022 What do you predict the final mass of magnesium oxide is? Why might this not be the case?

Mass Changes When a Reactant or a Product is a Gas January 2022 A small amount of marble chips was added to hydrochloric acid in a flask. 25 g of carbon dioxide was produced. The flask and contents originally weighed 270 g. What will be the mass of the flask and its contents now? How do you know?

Mass Changes When a Reactant or a Product is a Gas January 2022 A small amount of marble chips was added to hydrochloric acid in a flask. 25 g of carbon dioxide was produced. The flask and contents originally weighed 270 g. Since the total mass of products (and flask) must be 270 g, and 25 g of this is the carbon dioxide, there must be 270 – 25 = 245 g of products (and flask) left

Mass Changes When a Reactant or a Product is a Gas January 2022

Mass Changes When a Reactant or a Product is a Gas January 2022 Why might mass be lost in a chemical reaction? How could you measure the loss of mass in a chemical reaction? Using the particle model theory explain how mass is lost in a chemical reaction, even though the Law of conservation of mass means this should not be the case.
