Question

Barium chloride has various uses, such as manufacturing pigments and the bright green
color in fireworks (however, not recommended due to its toxicity). However, barium
chloride is highly toxic to human health. Assume that Barium Chloride and Sodium
Sulfate are the starting substances (reactants) in a reaction:

Answer 1

Write a balanced chemical reaction between Barium Chloride and Sodium Sulfate. Be
sure to include physical states.

Answer 2

is it BaC1(aq)+Na204(aq)---> BaSO4(s)+2Nacl (aq) ?

Answer 3

you have the right idea just be sure to correct typos

BaCl(aq) + Na2SO4(aq) ---> BaSO4(s) + 2NaCl (aq)

Answer 4

b. State the names of the products that are produced from this reaction.


Would that be BaSO4(s) ---> Barium Sulfate & 2NaCI (aq) ---> Sodium Chloride ?

Answer 5

yup good

Answer 6

Write complete total ionic and net ionic reactions for the balanced molecular equation in
part (a).

Complete Ionics--->Ba^+2 (aq) +2CI^-1(aq)+2Na^+1(aq)+SO4^-2(aq)---> 2Na^+1 (aq) +2CI^-1(aq)+BaSo4(s)
Net Ionics ----> Ba^+2(aq) +S04^-2(aq)---> BaSO4(s)

Answer 7

yup good

just want to correct something from before, the equation from part a should be

BaCl2(aq) + Na2SO4(aq) ---> BaSO4(s) + 2NaCl (aq)

(change BaCl to BaCl2 if you haven't already. Ba has a +2 charge so it should be BaCl2)

Answer 8

What (if any) precipitate (name and formula) forms in the reaction that you wrote in part
(a)?


Double Displacement Reaction?

Answer 9

it's asking for which compound is the precipitate (the solid compound that forms from the reaction) which means it's asking for BaSO4(s) since that's your solid product.

Answer 10

yeah I understand that but isnt that a double displacement reaction?

Answer 11

it's asking for the name and formula of your precipitate, which is barium sulfate/BaSO4.

double replacement reaction is the reaction type, not the precipitate name

Answer 12

okay is it insoluble precipitation? lol im confused

Answer 13

let's re-read the question

What (if any) precipitate (name and formula) forms in the reaction that you wrote in part
(a)?

it is asking what precipitate was made. or in other words, what solid compound was made from this reaction.

the name and formula of the precipitate are barium sulfate and Ba2SO4. that's what the question is asking for. simply "barium sulfate and Ba2SO4".

Answer 14

d. What (if any) precipitate (name and formula) forms in the reaction that you wrote in part
(a)?
e. What type of reaction(s) is/are being represented by the chemical reaction you wrote in
part (a)?



these were the question im little lost

Answer 15

you had the right idea for part e), it's a double replacement reaction since the two compounds "swapped" ions

Answer 16

okay so e is double replacement reaction
but now im still confused on part d

Answer 17

it is asking for the name and formula of your precipitate

the precipitate is the solid compound that forms from a precipitation reaction

your precipitate name is barium sulfate. its formula is BaSO4. that's all it's asking for.

Answer 18

So basically I put the precipitate is the solid compound that forms from a precipitation reaction. thats all for d?

Answer 19

it is asking for the name (barium sulfate) and the formula (BaSO4).

therefore, your answer is simply barium sulfate and BaSO4.

Answer 20

What is the % yield if 0.287 g of the solid product was actually obtained?


BaSO4 =1.401 g
0.287g/1.401 x 100% =20.49%

Answer 21

does it say how much reactant you started with?

Answer 22

nope

Answer 23

where did you get 1.401g then?

Answer 24

wait let me check my work im rushing through the question and I did some earlier

Answer 25

f. 1.25 g of barium chloride and 2.75 g of sodium sulfate are combined. Theoretically, what
mass of solid product could be formed from these amounts of reactants? What is the
limiting reactant?


this is the question before
lol this is all 1 question just parts

Answer 26

ok, I ran through your calculations and they look good

minor thing - 3 sig figs, so 20.5% not 20.49

Answer 27

Thank you

Answer 28

its weird but im lost on f

Answer 29

the limiting reactant?

1.25g barium chloride is 0.00600 moles barium chloride
2.75 sodium sulfate is 0.0471 moles sodium sulfate

based on the balanced equation, 1 mol barium chloride makes 1 mol barium sulfate

also, 1 mol sodium sulfate makes 1 mol barium sulfate

so 0.00600 moles barium chloride makes 0.00600 moles barium sulfate, and 0.0471 moles sodium sulfate makes 0.0471 moles barium sulfate, and since barium chloride makes the lower amount of product, barium chloride is your limiting reactant

Answer 30

woah you people are smart

Answer 31

So basically I answer barium chloride is the limiting reactant?

Answer 32

yeah

Answer 33

okay Im done with all my other questions I just want you to view them theyre much shorter

Answer 34

h-h-how? what grade are you in?

Answer 35

I want to vote both of you as best response
