Please help me answer this one chemistry question.
LiOH + CO2 → Li2CO3 + H2O how many grams of Li2CO3 are produced from the complete reaction of 71.85 g of LiOH ? |

First of all, I've only posted two questions. That one being my second. So why don't you shut up and go back to jerking your dad off.

why would anyone want to help you do your homework when you haven't contributed anything to the forum?

or why would anyone want to help you if you have a crummy attitude like that towards other members?

Try using a site like this one because this isnt a homework help site. And clean up your attitude a bit if you ever expect help from anyone on here.

It's not that hard of a question. Of all the places you can go for help, you come to a design geared site? And treating people like that isn't going to help.
Moved to School. (where the thread will probably die.) |

I think y'all are being a little unfair because other people have asked for help here before too, so why just attack this guy?
Anyway. It's simple stoichiometry. First you should balance the equation by putting a 2 in front of LiOH. Convert 71.85 g of LiOH into moles. (71.85g / 23.95g/mol = 3 moles of LiOH) Convert moles of LiOH into moles of Li2CO3. Mole ratio according to what is given is 2:1 so it would just be 1.5 moles of Li2CO3. Convert moles of Li2CO3 into grams. (1.5 moles x 73.89 g/mol = 110.8 g of Li2CO3). Answer: 110.8 g of Li2CO3 Mind you I haven't taken Chem in 2 years so I might be wrong. That is if you check this again. |

i think it's fair. if this was a regular posting member asking it then i wouldn't care. it's just the fact this person hasn't done anything on the forums but ask for homework help. i think it's annoying when people come around and don't want to contribute anything and only want someone to do their homework for them.
i don't think i attacked them either way though...i just stated it's not a homework forum i'm pretty sure i was attacked for pointing that out though. |
