Question

Is mass conserved when 10 g of sodium hydroxide undergoes a chemical change during an interaction with 57 g of copper sulfate? Use complete sentences to support your answer by explaining how this can be demonstrated.

Answer 1

In fact, it actually conserves mass. To illustrate this, we could use the sodium hydroxide reaction with copper sulphate. Simply place the sodium hydroxide solution beaker on the weighing balance along with the copper sulfate solution beaker and evaluate their total mass. After that, inject one mixture into the other and place the complete beaker with the reactor & product and also the empty beaker back on the balance scale, then weigh their combined mass. If you perform the calculations correctly, the total masses before and after the reaction will be equivalent. And note for every chemical reaction, there is neither mass produced or destroyed. Hope this helps you out.
