Juan inflates a balloon and then releases its end to let the balloon go free as air comes out. The balloon then flies around the room. Which statement describes how this example is an application of Newton’s laws of motion?

According to Newton’s first law of motion, the balloon continues moving until the forces on it are unbalanced.
According to Newton’s third law of motion, the balloon is pushed forward as the air is forced out.
According to Newton’s third law of motion, the balloon resists any change of motion unless an unbalanced force acts upon it.
According to Newton’s second law of motion, the balloon exerts a force on the air, which exerts a force back on the balloon.

  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
