Consider the molecule bf3. (a) what is the electron config- uration of an isolated b atom? (b) what is the electron con- figuration of an isolated f atom? (c) what hybrid orbitals should be constructed on the b atom to make the b–f bonds in bf3? (d) what valence orbitals, if any, remain unhybrid- ized on the b atom in bf3?

1. combine iron and copper (ii) sulfate solution. (hint: iron will form the iron (iii) ion) fe + cuso4 → 2. combine lead (ii) nitrate and potassium iodide solutions. pb(no3)2+ kl → 3. combine magnesium metal and hydrochloric acid solution. mg + hcl → 4. electrolysis (splitting) of water. h2o → 5. burning magnesium. mg + o2 →

What are the charges of the subatomic particles by choosing the answer from the drop down menu. protons have a (+1,0,or-1). (protons,neutrons,electrons) have a 0 charge. 3.) electrons have a (+1,0,-1)
