PART 4 – Controlling the Concentration Press Reset then Select CuSO4. Add enough to create a .5 Molar Solution in the ½ liter of water originally in the beaker. Create a 0.5 M solution using the copper(II) sulfate dropper. Then drain the solution, so that there is 0.5 L of this solution. If you were to now add water up to the 1L mark, what would the concentration of the solution be? Predict the concentration if the solution is diluted to a volume of 1 liter. Show the calculation of this concentration, include units in all your work.

- calcium has greater affinity to bond with electron receptors than hydrogen does and hence, it has the ability to replace hydrogen in most of its compounds.

- lithium has 2 valence electrons in the product because it can make only 1 bond with hydrogen. beryllium has 4 valence electrons in the product because it can only make 2 bonds. it has fewer electrons than neon and can react with electron donors. each hydrogen has 2 valence electrons, the same as helium.

- the covalent bond formed between carbon and hydrogen is polar because carbon is more electronegative than hydrogen and it attracts the bonded electron pair closer to itself, thus giving hydrogen a partial positive charge.

- a hydrogen bond is a relatively weak bond that hydrogen atoms make with the electronegative atoms nitrogen, oxygen or fluorine.

so the best choice is a.) 2 calcium (ca) atoms
