Question

For Part 1, describe the changes in the colors of the well, if any, as you go from well 1 to well 9—that is, as you go from the well with the least copper(II) nitrate to the well with the most copper(II) nitrate. Which wells had the most distinct precipitate?
For Part 2, describe the changes in the colors of the well, if any, as you go from well 1 to well 9—that is, as you go from the well with the least iron(II) sulfate to the well with the most iron(II) sulfate. Which wells had the most distinct precipitate?
For Part 3, describe the changes in the colors of the well, if any, as you go fr

i need help i don't understand

Answer 2

@JFraser

Answer 3

this is so confusing

Answer 4

yeah i don't like it at all

Answer 5

Answer 21

ok so maybe we can ask @JFraser

Answer 22

answering this is going to depend on you knowing what you did in this lab activity. I can make a few guesses, but what DID YOU DO in these wells?

did you mix each solution together?
did you dilute each solution with water?

I need more specifics

Answer 23

well i need help with this like step by step help @JFraser

Answer 24

and I would like to help you, but I don't know what you're doing in this lab. All you've given is the questions. What did the lab DO?

Answer 27

this is very confusing

Answer 28

ok i got the first question now

here is what i don't understand

Below are the balanced equations for the reactions in Parts 1–3. Review the results of your experiments and look closely over the mole ratios of the chemical reactions. Do your experiments reflect the stoichiometric, molar amounts indicated by the reactions? Discuss this using the evidence from your experiments.
Cu(NO3)2 (aq) + 2NaOH (aq)  Cu(OH)2 (s) + 2NaNO3 (aq) Note: Cu(OH)2 is a blue precipitate.
FeSO4 (aq) + 2NaOH (aq)  Fe(OH)2 (s) + Na2SO4 (aq) Note: Fe(OH)2 is a dark green precipitate.
Fe(NO3)3 (aq) + 3NaOH (aq)  Fe(OH)3 (s) + 3NaNO3 (aq) Note: Fe(OH)3 is a red-orange precipitate.

Answer 29

what did the lab DO in each row?

I could guess, but if you don't know what went on, any answer I give will be useless

Answer 30

ok good. oooooooo thts what u had to do

getting anywhwere?

Answer 40

all most i have to get four more things done that have to be done then i be back to finsh this

Answer 41

i believe i done this before but i am still looking for the right lab

Answer 42

o cool

Answer 43

so the lab will help me with the first question and then i need to find the next lab for the last question

Answer 44

ok

Answer 45

ok 2. Below are the balanced equations for the reactions in Parts 1–3. Review the results of your experiments and look closely over the mole ratios of the chemical reactions. Do your experiments reflect the stoichiometric, molar amounts indicated by the reactions? Discuss this using the evidence from your experiments.
Cu(NO3)2 (aq) + 2NaOH (aq)  Cu(OH)2 (s) + 2NaNO3 (aq) Note: Cu(OH)2 is a blue precipitate.
FeSO4 (aq) + 2NaOH (aq)  Fe(OH)2 (s) + Na2SO4 (aq) Note: Fe(OH)2 is a dark green precipitate.
Fe(NO3)3 (aq) + 3NaOH (aq)  Fe(OH)3 (s) + 3NaNO3 (aq) Note: Fe(OH)3 is a red-orange precipitate.
i know how to do because i found the lab for that

Answer 46

in the lesson there is to labs

Answer 47

first lab deals with Reactants

Answer 48

k

Answer 49

and the second lab deals with this Determine the amounts of reactants that are needed to produce chemical reactions.

Answer 50
