Mass Relationships In chemical Reactions
Purpose:
1. To predict the mass of the Cu(s) that will be produced when 2. ... To react the two substances, purify the Cu(s) and determine its mass. ...
Background/Introduction:
This lab is about using our stoichiometry skills to predict the mass of solid copper Cu(s) in the single replacement equation:
CuSO 5H O (aq) + Zn(s) ZnSO (aq) + Cu(s)
Stoichiometry is a method of predicting the amount or amounts of products using the amount or amounts of reactants. In this lab we will conduct an experiment to determine the exact mass of solid copper Cu(s) produced. ...
CuSO 5H O (aq) + Zn(s) ZnSO (aq) + Cu(s)
Variables:
The manipulated variable in this lab is the amount of CuSO 5H O (aq) while the responding variable is the mass of the solid copper Cu(s). The mass of solid copper is the responding variable because we measure it and it can differ if all the copper is not filtered from the beaker.
