This question is about copper(II) sulfate.
Blue hydrated copper(II) sulfate turns white when it is heated. The word equation for the reaction is: hydrated copper(II) sulfate (blue)⇌anhydrous copper(II) sulfate (white)+water\text{hydrated copper(II) sulfate (blue)} \rightleftharpoons \text{anhydrous copper(II) sulfate (white)} + \text{water}hydrated copper(II) sulfate (blue)⇌anhydrous copper(II) sulfate (white)+water
What does the symbol ⇌\rightleftharpoons⇌ mean?
A student heats 7.50 g7.50\text{ g}7.50 g of hydrated copper(II) sulfate in a crucible. 2.70 g2.70\text{ g}2.70 g of water is given off as steam. The remaining solid is anhydrous copper(II) sulfate.
Calculate the mass of anhydrous copper(II) sulfate produced.
