Answer:

4 L

Explanation:

using general gas equation formula (in blue pen in attached image),

P1 = 1 atm

V1 = 2.5 L

T1 = 25°C

P2 = 0.5 atm

V2 = x

T2 = 20°C

making V2 subject of the formula (in red pen in attached image),

V2 = 1*2.5*20/25*0.5

= 50/12.5

= 4 L

have a great day!!!

What mass of oxygen reacts when 84.9 g of iron is consumed in the following reaction: Fe+O2= Fe2O3
konstantin123 [22]
First we will calculate the number of moles of Iron:
n =  \frac{m}{M}
, where n is the number of moles, m is the mass of iron in the reaction and M is the Atomic weight.
n= \frac{84.9}{55.845} = 1,52 moles of Iron.
The same number of moles of Oxygen will take part in the reaction.
So 1,52= \frac{mOxygen}{32} where 32 is the Atomical Weight of Oxygen (16 x 2).
=>mOxygen=32*1,52=48,64g

<h2>The Answer is option d "polymers"</h2>

Explanation:

  • Polymers are also categorized as plastics.
  • Polymers are usually soft and ductile that is it can be drawn into wires.
  • Polymers have low heat capacity or heat conductivity that is the extent to which a polymer acts as an insulator towards the temperature.
  • Polymers can be opaque ( not be seen through), translucent or transparent (to be seen clearly through).
  • Hence the right answer is option d "polymers".
