Momentum = the product of mass and velocity = unit is kg m/s
Parti: Find the momentum in each picture:
Moss = 2500 kg
Velocity = 25m's
Mass=320
Velocity=12ms
Moss - 85 kg
speed=&m's
Changing the Momentum:
To change the momentum of an object, a
must be applied to the object. This action will
cause the
of the object to change. When the velocity increases, the momentum will
When the velocity
the momentum will decrease. The change in the
momentum of the object is called IMPULSE.

Explanation:

  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
