Atoms are unstable unless they have a similar number of protons and neutrons. To make the carbon atom stable, add six neutrons to it. What’s the mass number now?

Fill in the coefficients that will balance the following reaction: a0cr2(so4)3 + a1agno3

Asubstance is a good conductor of electricity which of the following best explains a probable position of the substance in a periodic table

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)
