10.) mega-bubble
phineas and ferb know what they are going to do today. they are going to compete in
the danville mega-bubble contest. in order to win, they need to know which bubble
gum will make the biggest bubbles. to prepare for the contest, they purchased five
different brands of bubble gum. they need your to decide which brand to use
during the contest. write an experiment to test the bubble size of the five bubble pum
brands so they can win the contest. where's perry?

c, 1a hope this

  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

considering the bohr theory, the type of connection that requires the transfer the answer conuldn't be right
