Please help fast. Only serious answer. Activity
of the remaining eligible members, 20 are interested in being the historian. To pick one of the 20, you decide to use the 6 lots numbered 0
through 5 and pick 3 of them to form a 3-digit number regardless of the order (in other words, 1-2-3 is the same as 3-2-1). For this activity, you will
use the fifth counting rule.
Rule 5: The number of ways of selecting r objects from Nobjects when order doesn't matter is
FICT
Question 1
How many outcomes will you have if you pick 3 numbers without the order mattering? Does the number of outcomes match the number of
candidates? Is this a fair method for picking the historian?

  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

hope this !
