How many moles of SnCl2 will be produced if 85.3 g of FeCl3 is reacted with an excess of Sn for the following reaction:2 FeCl3(s
Ronch [10]

Answer:

The answer to your question is 0.79 moles of SnCl₂  

Explanation:

Data

moles of SnCl₂ = ?

mass of FeCl₃ = 85.3 g

excess Sn

Balanced chemical reaction

                 2 FeCl₃  +  3 Sn  ⇒   3 SnCl₂  +  2 Fe

Process

1.- Convert the mass of FeCl₃ to moles

Molar mass of FeCl₃ = 56 + (35.5 x 3)

                                  = 56 + 106.5

                                  = 162.5 g

Use proportions to find the moles of FeCl₃

                       162.5 g -------------------- 1 mol

                         85.3 g -------------------  x

                         x = (85.3 x 1) / 162.5

                         x = 0.525 moles

2.- Find the number of moles SnCl₂

                     2 moles of FeCl₃ ----------------- 3 moles of SnCl₂

                     0.525 moles        ----------------- x

                     x = (0.525 x 3) / 2

                    x = 0.79 moles of SnCl₂

Consider the following reaction where Kc = 154 at 298 K.2NO(g) + Br2(g) 2NOBr(g)A reaction mixture was found to contain 4.64×10-
IgorLugansk [536]

Answer:

The reaction is not at equilibrium and reaction must run in forward direction.

Explanation:

At the given interval, concentration of NO = \frac{4.64\times 10^{-2}}{1}M=4.64\times 10^{-2}M

Concentration of Br_{2} = \frac{4.56\times 10^{-2}}{1}M=4.56\times 10^{-2}M

Concentration of NOBr = \frac{0.102}{1}M=0.102M

Reaction quotient,Q_{c} , for this reaction = \frac{[NOBr]^{2}}{[NO]^{2}[Br_{2}]}

species inside third bracket represents concentrations at the given interval.

So, Q_{c}=\frac{(0.102)^{2}}{(4.64\times 10^{-2})^{2}\times (4.56\times 10^{-2})}=106

So, the reaction is not at equilibrium.

As Q_{c}< K_{c} therefore reaction must run in forward direction to increase Q_{c} and make it equal to K_{c}.

45) George is making spaghetti for dinner. He places 4.01 kg of water in a pan and brings it to a boil.
lesya692 [45]
On adding salt.....The boiling temperature increases.....

So ∆t= KB * molality
=O.52*(58/58)/4
= O.52*1/4
= 0.13
So increase is 100+.13=100.13°c
