Ano ang pag kakaiba ng simposyum at critikal

Ang simposyum ay isang pagtitipon,pagpupulong o kumperensiyakaugnay ng isang paksa kungsaan maraming tagapagsalitaang magbabahagi omaglalahad para sa mgaimbitadong tagapakinig.

Ang critique ay ang paghimay sa iba’t ibangelemento at bahagi ng isang akdaupang makita kung ang bawatisa’y nakatutulong maipaabot angnais sabihin o mensahe ng akda  para sa mga mambabasa.

the first, second, and fifth options

  1.the balanced   chemical equation is as below

cu +   2 ag(no)₃ → cu(no₃)₂   +2 ag

2.the   much silver   produced   is   50.9 g

step 1: find the   moles of cu

moles =   mass÷   molar mass

  from periodic table the molar mass of cu = 63.5 g/mol

moles is therefore = 15.00 g÷ 63.5 g/mol = 0.236   moles

step 2: use the mole ratio to determine the   moles of ag

from equation above   cu: ag   is 1: 2

therefore the moles of ag   =0.236   moles   x 2/1 =0.472   moles

step 3: find the mass   of ag

mass = moles x molar mass

from periodic table   the molar mass of ag =107.87 g/mol

mass   = 0.472   moles x 107.87 g/mol = 50.9 g

3.   the   much   silver   collected worth is   1.797 oz

  convert   50.9 g   to oz

that is   1 gram = 0.0353 oz

          50.9 grams =?   oz

by cross multiplication

={(50.9 grams x 0.0353 oz) / 1   gram}   =1.797 oz
