If 8 moles of FeCl₃ react with 8 moles of O₂ what is the limiting reactant?

Chemistry
1 answer:
horrorfan [7]3 years ago
6 0

Answer:

FeCl3

Explanation:

We'll begin by writing the balanced equation for the reaction. This is shown below:

4FeCl3 + 3O2 —> 2Fe2O3 + 6Cl2

Thus, the limiting reactant can be obtained as follow:

From the balanced equation above,

4 moles of FeCl3 reacted with 3 moles of O2.

Therefore, 8 moles of FeCl3 will react with = (8 x 3)/4 = 6 moles of O2.

From the calculation made above, we can see that a lesser amount of O2 is needed to react completely with 8 moles of FeCl3. Therefore, FeCl3 is the limiting reactant.

Calculate the mass of 29.6 L of fluorine gas at STP.
Lunna [17]

Answer:

Mass = 25.08 g

Explanation:

Given data:

Volume of fluorine = 29.6 L

Temperature = standard = 273.15 K

Pressure = standard = 1 atm

Mass of fluorine = ?

Solution:

The given problem will be solve by using general gas equation,

PV = nRT

P= Pressure

V = volume

n = number of moles

R = general gas constant = 0.0821 atm.L/ mol.K  

T = temperature in kelvin

n = PV/RT

n = 1 atm × 29.6 L / 0.0821 atm.L/ mol.K × 273.15 K

n = 1.32 mol

Mass of fluorine:

Mass = number of moles × molar mass

Mass = 1.32 mol ×19 g/mol

Mass = 25.08 g

True or False: It is OK to use wet glassware for the aspirin synthesis without potentially affecting your yield
vesna_86 [32]

Answer:

False

Explanation:

Laboratory synthesis of aspirin is done by the acetylation of salicylic acid with the help of acetic anhydride .

As , the  acid anhydride is very sensitive to moisture , as it can hydrolyze into two molecules of  acids,

Hence , the reaction involving acid anhydride  are conducted in anhydrous solvents .

Hence ,

if water is  present in the glassware then , some of the acetic anhydride is wasted , Which in turns reduces the yield than that expected .

Write the condensed formula from left to right, starting with (CH3)x where x is a number.
pochemuha

Complete question:

Write the condensed formula from left to right, starting with (CH3)x where x is a number.

See attached image for the structure formula of the compound

Answer:

(CH₃)₂CHC(CH₃)₃ named as 2,2,3-Trimethylbutane

Explanation:

If we number the longest chain of the carbon starting from the left, we will observe that there are four carbons in the straight chain as shown in the image.

Starting from first carbon from the left of the carbon chain, at carbon number number 2, there two alkyl group, that is two methyl (CH3 is two). Also at carbon number 3, there are three alkyl group, that is three methyl (CH3 is three).

The condensed formula will be written as;

(CH₃)₂CHC(CH₃)₃

This compound is named as 2,2,3-Trimethylbutane, an isomer of Heptane

Calculate the molarity of 90.0 mL of a solution that is 0.92 % by mass NaCl. Assume the density of the solution is the same as p
jeka94
Answer is: molarity is 0,155 M.
V(solution) = 90,0 mL = 0,09 L.
ω(NaCl) = 0,92% ÷ 100% = 0,0092.
d(solution) = 1 g/mL.
m(solution) = V(solution) · d(solution).
m(solution) = 90 mL · 1 g/mL = 90 g.
m(NaCl) = 90 g · 0,0092 = 0,828 g.
n(NaCl) = 0,828 g ÷ 58,4 g/mol.
n(NaCl) = 0,014 mol.
c(solution) = 0,014 mol ÷ 0,09 L.
c(solution) = 0,155 mol/L.
