Monique heated the black substance with some corbon. Copper was formed. what are all the elements in the blue crystals ?

formula: CuSO4*5H20

Those blue crystals are copper sulfate crystals with the formula CuSO4*5H20. It has

To determine the elements present in the blue crystals, we need to analyze the information given. It is stated that Monique heated a black substance with carbon, resulting in the formation of copper. This suggests that the black substance was a copper-containing compound.

Now, let's focus on the blue crystals. Unfortunately, the given information does not provide any direct connection between the black substance and the blue crystals. Therefore, without further details or experimentation, it is not possible to determine the elements present in the blue crystals with certainty.

However, based on general knowledge, blue crystals could be associated with various compounds containing elements like copper, cobalt, or even chromium, depending on the specific circumstances. It is important to note that this is a speculative answer and may not accurately represent the elemental composition of the blue crystals in question.

To obtain a more precise answer, additional information, such as the specific reaction conditions, reactants, or any other relevant details, would be necessary.
