The hydrogen ion concentration is .

Explanation:

From the given,

Volume of NaOH = 500 ml = 0.500L

Moarity of NaOH = 0.156M

The number of moles of NaOH is calculated is a follows.

Substitute the given values.

Volume of = 500 ml = 0.500L

Moarity of = 0.100M

The number of moles of is calculated is a follows.

Substitute the given values.

NaOH is a strong electrolyte

The number of moles NaOH left in the solution is

Therefore, hydroxide ion concentration is 0.028 mol

The hydrogen concentration

Therefore, hydrogen ion concentration is ,

- 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
