Answer 7

Write the balanced equation for the reaction of acetic acid ( ) and sodium bicarbonate ( ).
HC2H3O2 + NaHCO3 ===> NaC2H3O2 + H2CO3
What type of reaction(s) took place?
acid-base reactions

2. Calculate the number of moles of that were required to neutralize the in the vinegar.
1 mole HC2H3O2 required for 1mole NaHCO3.

There is missing information to answer question 3 to 6.

7)HBr is a strong acid, ionizes completely;

Mole = (0.250 mol/L )( 0.0264 L) = 0.0066 mol

HBr> H+ + Br-
0.250 M . 0.250 M 0.250 M
0.0066 mol .. 0.0066 mol


H+ + OH- > H2O
0.0066 mol H+ neutralizes 0.0066 mol OH^- ion

CsOH is a strong base and it dissociates completely;

CsOH(aq) > Cs^+(aq) + OH^-(aq)
0.0066 mol < 0.0066 mol

Answer 8

I have no clue what I just said lol
