Using the reaction below determine the amount of Sulfur proceduced in grams (this is a limiting reaction question) 2 H2S + SO2 -
marusya05 [52]

Answer:

<u>= 2.2 g pf S. produced</u>

Explanation:

Balanced Reaction equation:

2H_{2} S + SO_{2} →  3S + 2H_{2} O

1 mole of H2S - 34.1g

? moles - 3.2g

= 3.2/34.1 =<u> 0.09 moles of H2S</u>

Also,

1 mole of S02 - 64.07 g

? moles - 4.42g

= 4.42/64.07 <u>= 0.069 moles of SO2</u>

<u />

<em>Meaning SO2 is the limiting reagent</em>

Finally, 3 moles of S -  32g of sulphur

0.069 mole = ? g of Sulphur

= 0.069 x 32

<u>= 2.2 g pf S.</u>

If the volume occupied by 0.500 mol of nitrogen gas at 0°C is 11.2 L, then the volume occupied by 2.00 mol of nitrogen gas at th
Paraphin [41]
Avagadros law states that volume of gas is directly proportional to number of moles of gas at constant pressure and temperature.
\frac{V1}{n1} =  \frac{V2}{n2}
where V -volume , n - number of moles 
parameters for the first instance are on the left side and parameters for the second instance are on the right side of the equation 
substituting these values in the equation 
\frac{11.2 L}{0.500 mol} =  \frac{V}{2.00 mol}
V = 44.8 L 
answer is C. 44.8 L

PLEASE HELP FAST! How many grams of NO are formed if 8.3 g of ammonia react with 11.8 g of oxygen? The reaction is 4NH3 + 5O2 --
stepan [7]

The mass of NO produced is 9.3 g; option D.

<h3>What mass of NO is produced from the reaction?</h3>

The mass of nitrogen (ii) oxide, NO, produced from the reaction is determined from the mole ratio of the reaction.

The mole ratio of ammonia to oxygen from the equation of the reaction is 4 : 5.

moles of oxygen = 11.8/32 = 0.368

moles of ammonia = 8.3/17 = 0.488

Oxygen is the limiting reactant.

Mass of NO produced = 0.369 * 4/5 * 30 = 9.4 g NO

In conclusion, approximately 9.3 g of NO is produced.
