How many liters of 
Kruka [31]
The balanced equation for the above reaction is as follows
C₆H₁₂O₆(s) + 6O₂(g) --> 6H₂O(g) + 6CO₂<span>(g)
the limiting reactant in the equation is glucose as the whole amount of glucose is used up in the reaction.  
the amount of </span>C₆H₁₂O₆ used up - 13.2 g
the number of moles reacted - 13.2 g/ 180 g/mol  = 0.073 mol
stoichiometry of glucose to CO₂ - 1:6
then number of CO₂ moles are - 0.073 mol x 6 = 0.44 mol
As mentioned this reaction takes place at standard temperature and pressure conditions, 
At STP 1 mol of any gas occupies 22.4 L
Therefore 0.44 mol of CO₂ occupies 22.4 L/mol  x 0.44 mol = 9.8 rounded off - 10.0 L
Answer is B) 10.0 L CO₂

I am a metal which can be drawn into thin wires
Gwar [14]

Answer:

Silver and copper

Explanation:

Siliver

Electrical conductivity=62000000(s/m)

Boiling point=2162

Melting point=961.78

Phase=solid

Copper

Electrical conductivity=59000000(s/m)

Boiling point =2927

Melting point=1084.62

Phase=soild

Metals like gold, silver and copper are drawn into thin wire and are used in an electric circuit because of their high electrical conductivity

Mostly Siliver and copper are used since using gold is much expensive.
