Question

complete it, and turn it in to the instructor as part of their laboratory report that is due on March 31, 2018. You must neatly show all your work. You may write on this page (including the back) and/or attach additional sheets, as needed. 1: In the reaction of acetic acid and sodium hydroxide, the stoichiometric coefficient for sodium acetate is: a.y 1 b.y 2 c.y- 3 Explain your answer 2: In the reaction of hydrochloric acid and barium hydroxide, the stoichiometric coefficient for barium hydroxide is: w HCI+x Ba(OH)2 y BaCl2+z H20 Explain your answer

Explanation / Answer

1.

w CH3COOH +x NaOH ---------------y NaCH3COO +z H2O

1 CH3COOH + 1 NaOH --------- 1 NaCH3COO + 1 H2O

according to the stochiometric equation on both sides the masses and atoms are equal

.so equilising the atoms on both sides, i,e equalising the number of atoms of Na,

In the reactant sides 1 mole of Na and 1 mole of CH3COO are present. so the product side also 1 mole of Na and 1 mole of CH3COO are present.

So y=1

The naswer is A

2)

   w HCl + x Ba(OH)2 ---------------y BaCl2 + z H2O

x= 1

The answer is A

According to the stochiometric equation to equalising the atoms on both sides

2 HCl + 1 Ba(OH)2 ------------- BaCl2 + 2 H2O
