Propane (C3H8) can be burned to produce heat for homes. The products of the reaction are CO2 and H2O. For complete combustion to
Natalija [7]

Answer:

1- 3 Moles of CO2  

2- 132 g of CO2  

3- 105,6 g of CO2

4- Limiting Reagent O2

<u>Products form based on limiting reagent (384g O2) :</u>

CO2: 316,8 g

H2O: 172,8 g

<u>Products form based on C3H8 (132,33 g):</u>

CO2: 396,99 g

H2O: 216,54 g  

Explanation:

<u>Atomic Masses:</u>

C: 12

H: 1

O: 16

<u>Molecular weights:</u>

C3H8: 44 g

O2: 32 g

H2O: 18 g

CO2: 44 g

C3H8 + 5 O2⇒ 3 CO2 + 4 H2O

C3H8 (44g)+ O2 (160 g) ⇒ CO2 (132 g) + H2O (72 g)

In 5 moles of O2 are produced 3 moles of CO2, equivalent to 132 g

For 160g of O2 are produced 132 g of CO2, so 128 g of O2

160 g  O2 ⇒ 132 g CO2

128 g  O2⇒ × = 105,6 g CO2

(128×132÷160= 105,6)

The limiting reagent is the substance that is totally consumed when the chemical reaction is complete. The amount of product formed is limited by this reagent, because the reaction cannot continue without it.

If I have 132,33 g of C3H8 and 384 g O2 we can calculate:

For          44 g of CH3H8  ⇒160 g of O2

With   132,33 g of CH3H8 ⇒ ×= 481,2 g of O2

(132,33×160÷44=481,2)

As this amount exceeds the quantity of O2 that we have, we can assume that the 384 g O2 will be totally consumed.

<u>Calculations of the products formed in base of quantity of O2 (limiting reagent):</u>

160 g  O2 ⇒ 132 g CO2

384 g  O2⇒ × = 316,8 g CO2

(384×132÷160= 316,8)

160 g  O2 ⇒ 72 g H2O

384 g  O2⇒ × = 172,8 g H2O

(384×72÷160= 172,8)

<u>Calculations of the products formed in base of quantity of C3H8 (excess reagent):</u>

     44 g  C3H8 ⇒ 132 g CO2

132,33 g  C3H8 ⇒ × = 396,99 g CO2

(132,33×132÷44=396,99)

     44 g C3H8 ⇒ 72 g H2O

132,33 g  C3H8⇒ × = 216,54 g H2O

(132,33×72÷44= 216,54)

Purification of chromium can be achieved by electrorefining chromium from an impure chromium anode onto a pure chromium cathode
miskamm [114]

Answer:

544.522 Hours

Explanation:

a) Mass = 12.5 kg = 12500 g

Now, Number of moles is given as

No of moles = Mass of Cr / Molar mass of Cr

=\frac{12500}{52}

= 240.38 moles

Cr^{3+}\Rightarrow 3 mols of electrons are required

\Rightarrow 240.38\times3 =721.14\text{mol of e-}

Converting moles of e- to coulombs of charge, (1 mol of electrons = 96500 C )

Q =721.14 mol×96500 C/mol

=69590010 of charge

We know that, Q = I×t

where Q is charge, I is current and t is time required.

\Rightarrow t =\frac{Q}{I}

=\frac{69590010}{35.5}

=196281.97 seconds

=\frac{1.96281\times10^5}{3600}

=544.522 Hours
