Answer: 5.66 dm3

Explanation:

Given that:

Volume of neon gas = ?

Temperature T = 35°C

Convert Celsius to Kelvin

(35°C + 273 = 308K)

Pressure P = 0.37 atm

Number of moles N = 0.83 moles

Note that Molar gas constant R is a constant with a value of 0.0082 ATM dm3 K-1 mol-1

Then, apply ideal gas equation

pV = nRT

0.37atm x V = 0.83 moles x 0.0082 atm dm3 K-1 mol-1 x 308K

0.37 atm x V = 2.096 atm dm3

V = (2.096 atm dm3 / 0.37atm)

V = 5.66 dm3

Thus, the volume of the neon gas is 5.66 dm3

0.50 mol A, 0.60 mol B, and 0.90 mol C are reacted according to the following reaction
algol [13]

Reactant C is the limiting reactant in this scenario.

Explanation:

The reactant in the balanced chemical reaction which gives the smaller amount or moles of product is the limiting reagent.

Balanced chemical reaction is:

A + 2B + 3C → 2D + E

number of moles

A = 0.50 mole

B = 0.60 moles

C = 0.90 moles

Taking A as the reactant

1 mole of A reacted to form 2 moles of D

0.50 moles of A will produce \frac{2}{1} = \frac{x}{0.50}

thus 0.50 moles of A will produce 1 mole of D

Taking B as the reactant

2 moles of B reacted to form 2 moles of D

0.60 moles of B reacted to form x moles of D

\frac{2}{2} = \frac{x}{0.6}

x = 2 moles of D is produced.

Taking C as the reactant:

3 moles of C reacted to form 2 moles of D

O.9 moles of C reacted to form x moles of D

\frac{2}{3} = \frac{x}{0.9}

= 0.60 moles of D is formed.

Thus C is the limiting reagent in the given reaction as it produces smallest mass of product.

A cr3+(aq) solution is electrolyzed using a current of 7.40
oee [108]
When Cr+3  + 3e-  → Cr(s)

So according to the charge formula:

charge Q = I * t 

when we have I (the current) = 7.4 a

and t (the time in seconds) = 1.85d * 24h * 60 min*60sec=  159840 sec

by substitution:

Q = 7.4 a * 159840 sec = 1182816 C

now to get the mass we have to use Faraday constant which is:

F = e NA

   = 1.602 x 10^-19 * 6.022 x 10^23

  = 96485 C mol^-1

when e is the electron charge & NA Avogadro's number for the charge in on mol 

and as we can see from the equation Cu3+ reacts with 3 electrons so,

the mass of Cr(s) = Q* (1mole-/F) * (1molCr / 3 mol e-)

                            = 1182816 * (1/96485) * (1/3)

                            = 4.1 g
