Calculate the volume of 0.684mol of carbon dioxide at s.t.p. show working
solong [7]

Answer: The volume of 0.684 mol of carbon dioxide at s.t.p. is 15.3 L

Explanation:

According to ideal gas equation:

PV=nRT

P = pressure of gas = 1 atm (at STP)

V = Volume of gas = ?

n = number of moles = 0.684

R = gas constant = 0.0821Latm/Kmol

T =temperature =273K   (at STP)

V=\frac{nRT}{P}

V=\frac{0.684\times 0.0821L atm/K mol\times 273K}{1atm}

V=15.3L

Thus the volume of 0.684 mol of carbon dioxide at s.t.p. is 15.3 L

1. In a bowl, is 1/4 cup of water is added to 1 oz. of glue. Add coloring if you wish to.

2. 1/4 cup of Borax solution, also known as Sodium Tetraborate is added to the mixture and gradually stirred.

3. The mixture is kneaded with the hands to ensure a smooth consistency.

4. Water remnants are discarded and the slime is stored in a plastic bag and kept in the fridge.

B.

What each ingredient does

Polyvinyl acetate present in the glue acts as a liquid polymer.

Borax binds the liquid polymers together.

Water eases the mixing process

C.

If lesser ingredients are used, the slime will not have its characteristic slimy nature. If excess of the ingredients are used, the slime becomes very sticky.
