A student heats 2.796g of zinc powder with 2.414g of sulphur.He reported that he obtained 4.169g of zinc sulfide and recover 1.0
Sati [7]

Answer:

The mass of reactants and products are equal hence the reaction obeys law of conservation of mass

Explanation:

The law of mass conservation states that for a closed system to all transfer of mass, the mass of system must remain constant over time. This means for a chemical reaction, the mass of reactants must equal the mass of products.

if 2.796g of Zn reacts with 2.414g of sulphur to produce 4.169g of ZnS ad 1.041g of unreacted sulphur, then it means that accorfing to the law of mass conservation, the mass of reactants (zinc and sulphur), must be equal to mass of products (zinc sulfide and unreacted sulphur)

Mass of reactants = 2.796g + 2.414g =5.21g

Mass of products = 4.169g + 1.041g=5.21g

A battery has chemical energy, which can be used to generate thermal and radiant energy in a lightbulb. Which best explains what
WARRIOR [948]

Answer is: The total energy in the system remains the same as the decrease in chemical energy equals the increase in thermal and radiant energy.

The law of conservation of energy states that the total energy of an isolated system remains constant; energy can neither be created nor destroyed; it can only be transformed or transferred from one form (in this example chemical energy) to another (in this example thermal and radiant energy).

Radiant energy or light is the only kind of energy we can see with our eyes. Light have different wavelenght and different color.

Chemical energy - this type of energy is often found in things like batteries or food.
