Question

Which answer below correctly identifies the type of change and the explanation for the heating of copper sulfate pentahydrate?
1) physical change because even though the change caused the temperature of the copper sulfate pentahydrate to increase, the compound’s physical properties remained exactly the same
2)physical change because even though gas formation was observed, the copper sulfate pentahydrate was undergoing a state change, which means that its properties are preserved
3)chemical change because gas formation was observed along with a color change, which indicated that the copper sulfate pentahydrate was transformed into a different substance
  4)chemical change because a temperature change was observed, which indicated that the copper sulfate pentahydrate was transformed into a different substance

Answer 1

Answer:

chemical change because gas formation was observed along with a color change, which indicated that the copper sulfate pentahydrate was transformed into a different substance

Explanation:

i took a test

Answer 2

While heating copper sulfate pentahydrate chemical change occur because the gas formation was observed along with a color change, which indicated that the copper sulfate pentahydrate was transformed into a different substance, therefore the correct answer is the option C.

What is a chemical reaction?

A chemical reaction is a process in which one or more substances, also known as reactants are converted to one or more different substances, known as products. A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products.

As we heat copper sulfate pentahydrate it changes its color which indicated that the copper sulfate pentahydrate was transformed into a different substance,

Thus, The copper sulfate pentahydrate underwent a chemical change during heating because gas was formed and the color of the copper sulfate pentahydrate changed, indicating that it was changed into another substance. Therefore, option C is the correct response.
