Chemistry? 10 points to the first correct answer?


write balanced equation, use stoichiometry calculate number of moles of product. use molar mass calculate mass of product 15.0g of starting material.

2 ch3cooag + cuso4 ==> ag2so4 + cu(ch3coo)2

15.0mg = .015g

ch3cooag = 166.91g / mol

cuso4 = 159.61g / mol

agso4 = 311.80g / mol

cu(ch3coo)2 = 181.63g / mol



divide 0.015g molar mass of reactants.


agch3coo = 0.015g x 1mol / 166.91g = 8.99 x 10^5mol

cuso4 = 0.015g x 1mol / 159.61g = 9.40 x 10^5mol



use chemical equation find number of moles of product. silver acetate limiting reactant.


8.99 x 10^-5 ch3cooag + 9.40 x 10^-5 cuso4 = ag2so4 + cu(ch3coo)2

**made mistake here, fixed**
silver acetate limiting reactant use 4.5 x 10^-5mol of agso4 because of 2:1 ratio of ag. ch3coo has 2:2 ratio don't change it.

8.99 x 10^-5 ch3cooag + 8.99 x 10^-5 cuso4 = 4.5 x 10^-5 ag2so4 + 8.99 x 10^-5 cu(ch3coo)2



multiply number of moles of product molar masses


4.50 x 10^-5mol ag2so4 x 311.80g / mol = 0.014g ==> 14mg

8.99 x 10^-5mol cu(ch3coo)2 x 181.63g / mol = 0.016g ==> 16mg

hey can describe me in detail how find answer problem, have correct answer don't know how find it,
silver acetate , copper(11) sulfate react in double replacement reaction. if 15.0 mg of each reactant used, how of each product forms?

Connections Academy...?

trying go connections academy because of bullying has been going on since second grade. have created presentation, sent multiple emails, printed handouts , packets, , have had family come on discuss issue well....however, mom doesn't focus on initiative taking of information up. completely, 100% against connections academy because feels isn't normal school kids attend , if don't go high school, won't have "high school experience." understand many of disagree persistence on topic. however, bullying hurtful when in situation in , have bad anxiety backfiring.... unfortunately, mom feels private or charter school better option don't think eliminate bullying, many teenagers relatively bullying regardless. instead of allowing me attend connections academy, mom wants other options find insulting , unnecessary because can fixed through online school instead of dealing problem other people causing. example, mom researching physiologists, anti-...

Is there any website which would tell the history if we provide the second name or surname?

http://www.surnamedb.com/ these websites commercial businesses , lots of information taken pinch of salt...that stretch truth, names words , words come languages...so country spoke or influenced langauge, name have come from............ surname taken/given, choice first names now, expect find people called peter had exact same history , came same place....no silly...same surnames http://familytimeline.webs.com/originsof... if provide second name or surname have information place , origin , little other information useful. if know websites kindly provide them Arts & Humanities Genealogy Next
