You have two test tubes. One test tube contains Pb 2 (aq) solution and the other test tube contains Cu 2(aq). Predit what will happen when HCl (aq) is added to both test tubes. If a reaction occurs, what is the new chemical fomula?

How does decreasing the gas volume affect the pressure of a gas?

There is a single path for electrons. the current decreases when additional resistors are added. the current will be the same in each resistor. these statements best describe a(n) circuit.

Predict the reactants of this chemical reaction. that is, fill in the left side of the chemical equation. be sure the equation you submit is balanced. (you can edit both sides of the equation to balance it, if you need to.) note: you are writing the molecular, and not the net ionic equation. > cacl2(aq) + h20(l)
