Help Me With My Daughter's Homework Please!


Recommended Posts

Does anyone know what the product of zinc and ethanoic acid (formerly known as acetic acid) is? I am, officially, thick. We've done internet searches and we can't find it. Apparently I am even too thick to do an internet search in order to find the answer. I have suggested that she writes, 'Who knows' as the answer to this question but she seems loathe to do that. The bright spark who knows the answer to this question will receive an imaginary box of chocs, bouquet of flowers, weekend at a health spa...

acid on a metal will corrode so I would think thats ascetic acid on zinc will fizz and bubble and eat into the metal.

Did a bit of a search but to tired to do one in depth if i find out more i'll let you know

is the answer zinc chloride and hydrogen gas I am sure some very wise person will be along soon who is more knowledgeable than I am Good Luck

try going to wpbschoolhouse.btinternet.co.uk they have a chemistry section that might help seems that ethanoic acid is used in fizzy drinks i think

I'm not being cheeky Moose :(

That is wht I googled :(

 

Do you think its the zinc cream you put on babies bottoms for nappy rash :oxD

might help

 

or this?

 

Don't know if I've passed the Google search test and get virtual chocs ( great for weightwatcher like me :o )

As for Chemistry, the only Chemistry I know is the type between my husnabd and I :( and no we don't create gas xD

husnabd :oxD:(

 

my keyboard skills are not to GCSE level either, seem to be making a lot of these mistakes lately. :(:(

Well, we must be really thick too!!!

 

Hubby was determined to be the one to find the answer - trust a bloke and their competitive streak!

 

He's been all round the net and can only find what happens when the two come into contact!

 

He was really miffed - but I did chuckle!!

 

Hope you have more luck with someone else!! :o

It is Y9 chemistry. How do you know the answer you clever old thing?

Posted

Does it make a difference whether it's just zinc or zinc oxide? I have no idea but my daughter wonders if it makes a difference.

Posted

You don't happen to know the chemical formula too, do you? I'm taking the michael now, aren't I?!

Posted

I would like to say I understand but that would be a lie! I am very dense. Where did you find the answers or are you just a family of geniuses or should that be geni? I've sent your imaginary prizes and hope you're enjoying them. What the hell - imaginary prizes to everyone who helped - enjoy!

 

And do you know the formula? Extra prizes will be sent!

I'll ask my hubby - he is a science teacher- at secondary level and is a whizz- being a deputy head .. very good at science

...hang on a mo...

Posted

Sorry not sure of the formular as that is not one of the questions on Amys work sheet! I do have her teachers son in my class but I dont think he would appreciate me phoning him!!The rest of the answers were in her work book. At a guess next weeks prep will be on Reactions of metals!

I don't think there can be a direct product. I think there mat be a misunderstanding in that Zinc forms a salt with ethanoic acid and another acid.An example is below

CH3COOH + 2HCl + Zn --> CH3CHO + H2O + ZnCl2

Ethanoic acid + Hydrochloric acid + Zinc - Acetaldehyde + water plus zinc chloride

Lost as to all this foreign language and lost to why? Why does a 13 year old need to know this? I mean in the grand scheme of things :oxD

Posted

I thought I was in the wrong forum for a minute!

 

I am told on good authority:

 

Zn + 2(Ch3COOH) >> Zn(CH3CO2) + H2 (zinc ethanoate/acetate and hydrogen)

 

Incidentally its sometimes used in throat tablets as well as to treat wilson's disease.

 

Zinc oxide and ethanoic acid would give zinc ethanoate and water.

 

tales me back to Alevel Chemistry days...

 

Moose do tell us how your daughter gets on
