Chemistry
1 answer:
Leni [432]3 years ago
7 0

Answer:

3

Explanation:

Al + CuSO₄ → Al₂(SO₄)₃ + Cu

two aluminum atoms in products. put 2 in front of Al in reactants.

2 Al + CuSO₄ → Al₂(SO₄)₃ + Cu

three sulfur atoms and twelve oxygen atoms in products. put 3 in front of CuSO₄ in reactants.

2 Al + 3 CuSO₄ → Al₂(SO₄)₃ + Cu

three copper atoms in reactants. put 3 in front of Cu in products.

2 Al + 3 CuSO₄ → Al₂(SO₄)₃ + 3 Cu

The equation is balanced. Hope that helps.

______________ is a durable material and is widely used for casting, which is a process by which the melted material is poured i
podryga [215]

The material that has been widely used in casting has been copper. Thus, option C is correct.

Casting has been the process of molding the liquid into a specific shape with the mold. The casting involves the heating of elements and converting them into liquid. The liquid has been poured into the mold and cooling results in the casted material.

The casted material has been selected based on the boiling temperature, cooling temperature, resistivity, cost-effectiveness, and damping ability.

The material that has been consisted of these characteristics has been copper. Thus, copper has been commonly used for casting. Thus, option C is correct.

Two solids of identical mass, A and B, are analyzed using identical calorimeters. Each calorimeter contains the same amount of w
DIA [1.3K]

Answer:

Specific heat of solid A is greater than specific heat of solid B.

Explanation:

In the calorimeter, as the temperature is increasing, the vibrational kinetic energy will increase and this means that additional amount of energy will be needed to increase the temperature by the same value. Therefore, we can conclude that specific heat increases as temperature increases.

Now, we are told that the final temperature of solid A's calorimeter is higher than that of B.

This means from our definition earlier, Solid A will have a higher specific heat that solid B.
