How many liters of 4.0 M NaOH solution will react with 1.8 mol H2SO4? (Remember to balance the equation.) H2SO4 + NaOH → Na2SO4 + H2O

The correct answer is 0.9 Liters.

Explanation:

Based on the given reaction:  

2NaOH (aq) + H₂SO₄ (aq) ⇒ Na₂SO₄ (aq) + 2H₂O (l)

It is clearly evident from the reaction that one mole of sulfuric acid reacts with two moles of sodium hydroxide. So, 1.8 moles of H₂SO₄ will react with,  

2/1 × 1.8 mol = 3.6 moles of NaOH

The molarity or M of NaOH given is 4.0 M, the moles of NaOH given is 3.6. Now the volume of NaOH can be determined by using the formula,  

Molarity = no of moles/volume in Liters

4.0 = 3.6/V

V = 3.6/4.0 = 0.9 L

Hence, 0.9 Liters of 4.0 M NaOH will react with 1.8 moles of H₂SO₄.  

- 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
