Question

60.00 grams of hydrochloric acid react with sodium hydroxide.
- write the balanced reaction with the correct products
- what is the reaction type?
- what is the theoretical yield of sodium chloride (in grams)? using dimensional analysis
- what is the percent yield of 84.05 grams of sodium chloride are actually produced?

Answer 1

NaOH + HCl -->
switch the cations to get

NaCl + HOH (better to write HOH as H2O, though) as the products

Answer 2

"reaction type" honestly depends on what level of chem this is, if they're talking about the movement of ions this is a double replacement (since both of them swap their cations with each other), if they're talking about what actually is happening, chemically, this is an acid-base neutralization reaction

Answer 3

theoretical yield of sodium chloride:

start with 60.00g HCl as stated in the problem
divide by the molar mass of HCl to get moles of HCl

you have a 1:1 ratio of HCl and NaCl according to the equation.
so moles of NaCl = moles of HCl

so from there you can just multiply by molar mass of NaCl to get theoretical yield

Answer 4

percent yield = divide (actual yield)/(theoretical yield) and multiply by 100%

don't forget sig figs on questions 3 and 4

Answer 5

thank you..
can you check my work for theoretical yield?
60.00g / 36.36
= 1.65 * 58.44
= 96.42
I might be missing a step here ^

Answer 6

generally you don't want to round until the very end

60.00g / 36.36 * 58.44 = 96.44g

Answer 7

otherwise good

Answer 8

ah okay! thanks!

Answer 9

Hi, sorry coming back to this question. For theoretical yield its right but I need to do dimensional analysis for it. Are you able to help me with it?

Answer 10

thank you!!
