when working with newton’s third law, there has to (s) involved.

a. four

b. one

c. three

d. two

When working with Newton’s Third Law, there has to be two objects involved.

Option D

Explanation:

Third law by Newton defines that the action and the reaction forces acting on different bodies. For any object under action, there will be an opposite force called reaction acting on the body.  Let us consider the movement of a car onto the home way.

A car seems to be well-equipped with wheels which rotate. While rotating or spinning, the wheel grips the road and instantly, the road is pushed backwards. Since force results due to mutual interactions, the road acts to push the wheels forward. Likewise, we have many examples like moving fish, motion of birds, etc.

  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
