When you cook food like eggs, this is a chemical change. Agree.
The runny egg turns into a solid. One type of matter must be changing into another type
When you cook food like potatoes, this is a chemical change. Agree.
Boiling potatoes causes changes in the structure of the starch. Higher heat as in baking, roasting, or frying causes the development of a harder crust on the potato. This suggests that chemical changes have taken place.
When a candle burns, the wick of the candle and wax turn into nothing. Disagree.
The <em>Law of Conservation of Mass</em> says that <em>you can’t turn matter into nothing</em>. What must be happening is that the wick and the wax are changing into other substances that we can’t see, such as colourless gases of carbon dioxide and water vapour.

"H2" is the one among compound the following choices given in the question that is a molecule. The correct option among all the options that are given in the question is the third option or the penultimate option. The other options are all salts. I hope that this is the answer that you were looking for and the answer has actually come to your desired help.
Answer:
Dependent variable
Explanation:
In every experiment, there must be a dependent variable and an independent variable.
The independent variable is that variable that you have to manipulate in order to receive a response. E.g, in the experiment described in the question, the amount of sunlight a sunflower plant receives is the independent variable.
The dependent variable is the number of seeds produced. It is the response obtained by carefully manipulating the amount of sunlight
