Question:
How many grams of zinc are created by treating 81 g of aluminium with zinc(II) chloride?
How many grams of zinc are created by treating 81 g of aluminium with zinc(II) chloride?
Answer:
Balanced equation is 2 Al + 3 ZnCl2 - 2 AlCl3 + 3 Zn - Use molar mass to find moles of Al used : (81 g Al) x (1 mole Al / 27.0 g Al) 3.0 moles Al - Then use the coefficients of the balanced equation to find the number of moles of zinc produced : (3.0 moles Al) x (3 moles Zn / 2 moles Al) 4.5 moles Zn - Then use molar mass again to convert the moles of Zn to grams : (4.5 moles Zn) x (65.4 g Zn / 1 mole Zn) 294.3 g Zn ~~~~~~ Note that is the theoretical yieldAn actual experiment/reaction would yield lessAlso, my result of 294.3 g Zn may not be correct because of significant figuresThe only number in the given information is 81 g of Al, which has two significant figures, so the result should also be rounded to two s.fRounding my answer to 2 s.fis 290 g Zn .
Trust me, it's safeI have two cockatiels at home, and they LOVE to play with and chew stringSoyeah, as long as your bird doesn't actually swallow it, it would be okay to use string;)
i does no longer tie a string to her footit may decrease her move and reason harmi does no longer take her outside, bothBirds are gentle, and a unexpected temperature replace can deliver forth a moult.
I have an Indian Ringneck Parakeet, and his favourite toy is stringI tie string in knots and add beads and things like that, and they are his all time favourite! Aswell, when you visit a pet store lots of the parakeet toys are made out of string, as birds love to chew all day! I would reccomend making her a few toys and I can assur you she will love them! Aswell, I was cleaning my room and I found an old bag that I was going to bin, but instead I cut off the thin leather arms, washed them, threaded some shower/curtain rail hangers on there, and it is now his favourite toy! (Just an idea for you guys) My indian ringneck loves this sort of things, and so will your parakeet! Hope I have helpedMerry Christmas Jessie!

Yes, string can kill a birdIf you have a quick link that would be much safer.
