you need ten quarters
metal kitchen foil
blotting paper
two pieces of copper wire
cider vinegar
salt
bowl
LED- light emitting diode
&masking tape
1.Mix vinegar and a little salt together in the bowl. Vinegar is acetic acid and all acid can be used as an electrolyte.common salt is sodium chloride,a combination of a positive and negative ion (Na+ and Cl-). These will separate in the electrolyte, increasing it's strength.
2. Soak your circles of blotting paper in the ion-rich electrolyte.
3. With the masking tape, attach the end of one wire to the underneath of a foil disk. This is the negative terminal.Now stack in this sequence-foil,paper,coin,foil,paper,coin.
Each combination is it's own tiny battery-but light an LED you'll need quite a few of these cell's
4. When you have a stack,you can attach a wire to the last coin with tape. This will be the positive terminal.
Get the right attachment named the " Living Quarters Key" and solve it with the steam battery.
16 Quarters to make 4 dollars $1=0.25 $1= 4 Quarters. 4 x 4=16 Quarters Therefore 16 quarters make $4.00
160 quarters 4 quarters = 1 dollar 160 quarters = 40 dollars
4 quarters make$1.00
there are ten quarters in two and a half. two quarters make a half and eight quarters make two. 8quartesr+2quarters=10quarters
4 quarters make up a dollar.
Two quarters go together to make one half.
4 quarters make one. ¼+¼+¼+¼=1. Also four quarters make a dollar: 25¢ + 25¢ + 25¢ + 25¢ = $1.00
Two quarters make a half.
4 quarters make a whole thus 11 quarters make up 2 wholes and 3 quarters left over.1 quarter is 25% and therefore 3 quarters = 75% which is the same as 0.75Thus 11 quarters = 2.75 as a decimal.
12 quarters make 3.00 .
32 quarters
