Sodium chloride is produced from its elements

Chemistry
1 answer:
Kisachek [45]3 years ago

Answer:

                     Mass of Sodium  =  574.75 g

                     Mass of Chlorine  =  886.25 g

Explanation:

                   The  balance chemical equation for the synthesis of NaCl is,

                                        2 Na + Cl₂ → 2 NaCl

Step 1: <u>Find out moles of each reactant required,</u>

According to balance chemical equation,

                 2 moles of NaCl is produced by  =  2 moles of Na

So,

         25 moles of NaCl will be produced by  =  X moles of Na

Solving for X,

                     X  =  25 mol × 2 mol /  2 mol

                     X  =  25 moles of Na

Similarly for Cl₂,

According to balance chemical equation,

                 2 moles of NaCl is produced by  =  1 mole of Cl₂

So,

         25 moles of NaCl will be produced by  =  X moles of Cl₂

Solving for X,

                     X  =  25 mol × 1 mol /  2 mol

                     X  =  12.5 moles of Cl₂

Step 2: <u>Convert each moles to mass as;</u>

Mass  =  Moles × Atomic Mass

For Na,

Mass  =  25 mol × 22.99 g/mol

Mass  =  574.75 g

For Cl₂,

Mass  =  12.5 mol × 70.90 g/mol

Mass  =  886.25 g

A tank of oxygen has a volume of 1650 L. The temperature of the gas inside is 35?C. If there are 9750 moles of oxygen in the tan
Paul [167]

Answer:

2192.64 PSI.

Explanation:

  • From the general law of ideal gases:

<em>PV = nRT.</em>

where, P is the pressure of the gas in atm.

V is the volume of the container in L (V = 1650 L).

n is the no. of moles of the gas in mol (n = 9750 mol).

R is the general gas constant (R = 0.082 L.atm/mol.K).

T is the temperature of the gas in (T = 35°C + 273 = 308 K).

∴ P = nRT/V = (9750 mol)(0.082 L.atm/mol.K)(308 K)/(1650 L) = 149.2 atm.

  • <u><em>To convert from atm to PSI:</em></u>

1 atm = 14.696 PSI.

<em>∴ P = 149.2 atm x (14.696 PSI/1.0 atm) = 2192.64 PSI.</em>

Type the correct answer in the box. The pressure inside a tire is measured as 28.0 . What is its pressure in ? 1 pound = 4.45 ne
posledela

The pressure is 19.3 N/cm².

<em>p</em> = (28.0 lb/1 in²) × (4.45 N/1 lb) × (1 in²/6.45 cm²) = 19.3 N/cm²
