A 6.00 L container of N_2 has a temperature of 273 K. Calculate the volume if the temperature is doubled.
vfiekz [6]
V1/T1 =V2/T2 (using charles law)

V1=6.00
V2=?
T1=273
T2=273

Making V2 the subject of formula the equation then becomes

V2= V1xT2/T1

6.00x263/273=6.0L

Iron metal reacts with elemental oxygen to form rust according to the unbalanced reaction, Fe(s) + O2(g) → Fe2O3(s),. What is th
pochemuha

Answer:

c. 3

Explanation:

The unbalanced reaction expression is given as:

          Fe  +  O₂  →   Fe₂O₃  

To balance the expression gives the coefficient of oxygen.

Assign the coefficients a,b, c and use a mathematical approach to solve this problem:

             aFe  +  bO₂  →  cFe₂O₃

Conserving Fe: a  = 2c

                    O:  2b  = 3c

Now let c = 1, a  = 2, b  = \frac{3}{2}

  Multiply through by 2,

             a = 4, b = 3 and c  = 2

 

               4Fe  +  3O₂  →   2Fe₂O₃  

The coefficient of O₂ is 3
