They sound like they should mean something similar! However, chemistry uses words very carefully, and these words have very specific meanings. Strong acids completely dissociate in water....
a) 2.8.7 (A chlorine atom has 17 protons and therefore 17 electrons. The first shell holds 2 electrons, and those after hold 8 electrons) b) Chlorine exists as a diatomic molecule at room temperatur...
Balancing chemical equations requires the same quantity of products as reactancts. There are two atoms of H on the left and therefore two on the left; one SO4 on the left thus one on the right; however wh...
Bonding is about the movement of electrons-electrons are NEGATIVELY charged-the electrons move to allow atoms to become more STABLE by having a full outer shell of electrons-The periodic table is useful t...
As the question is 2 marks, show working to ensure you get a mark even if answer is slightly wrongFrom periodic table you can see that the relative atomic masses are oxygen = 16; aluminium = 27; sulfur = ...
