Barium chloride (BaCl2) is an inexpensive, soluble salt of barium that has wide application in the laboratory, including in the gravimetric determination of the presence of sulfate ions. Solid barium chloride can be produced through the decomposition reaction of solid barium chlorate (Ba(ClO3)2) which also produces oxygen gas. When 7.25 g of barium chlorate decomposes completely, 4.96g of barium chloride is produced.

Write a balanced chemical equation for the decomposition of barium chlorate. (2 marks)

Using your understanding of the conservation of mass, determine how much oxygen is produced. (1 mark)

If 5.00g of barium chlorate was used instead, how much more barium chlorate would be required to produce the same amount of barium chloride? (2 marks)

If you tripled the amount of barium chlorate, what would be the effect on the total mass of products? (2 marks)

If the decomposition of 7.25g of barium chlorate produced only 3.72 g of barium chloride and 1.72 g of oxygen, how much barium chlorate did not decompose? (2 marks)

The diagrams show objects’ gravitational pull toward each other. which statement describes the relationship between diagram x and y? gravity attracts only larger objects toward one another. gravity attracts larger objects only if they are close to one another. if the masses of the objects increase, then the force between them also increases. if distance between the objects increases, then the amount of force also increases.
