susana heats up a sample of red crystals. while the sample is being heated, a gas is released and a blue powder is left after the heating. is the sample of red crystals an element or a compound? explain your answer.
Answer
Brief Explanations:
Elements cannot be broken down into simpler substances by chemical means. Since the red - crystal sample decomposes into a gas and a blue powder upon heating, it is not an element. Compounds can be decomposed into simpler substances through chemical reactions like heating. So, the red - crystal sample is a compound.
Answer:
The sample of red crystals is a compound because it decomposes into a gas and a blue powder upon heating, which indicates it is made up of two or more elements chemically combined.
