In the balanced molecular equation for the neutralization of sodium hydroxide with sulfuric acid, the products are:
earnstyle [38]

The balanced molecular equation for the neutralization of sodium hydroxide with sulfuric acid is:

Sodium hydroxide + Sulfuric acid →  Sodium sulfate +water

<h3>What is the balanced molecular equation?</h3>

A balanced equation is an equation for a chemical reaction in which the number of atoms for each element in the reaction and the total charge is the same for both the reactants and the products. In other words, the mass and the charge are balanced on both sides of the reaction.

In the given reaction, the reactants have been sulfuric acid and sodium hydroxide. Thus, these are written on the left side of the right arrow. The sodium sulfate and water have been the products and written on the right side of the right arrow.

The balanced molecular equation for the neutralization of sodium hydroxide with sulfuric acid is:

Sodium hydroxide + Sulfuric acid →  Sodium sulfate +water

Starting with a vessel of temperature 50.1°C, a pressure of 6263.MmHg and volume 461.1mL, what is its final volume, in liters, i
il63 [147K]

Answer:

The value of final volume inside the vessel  V_{2} =  5.17 ml

Explanation:

Initial pressure P_{1} = 6263 mm Hg = 8.24 atm = 835 K pa

Initial temperature T_{1} = 50.1 ° c = 323.1 K

Initial volume V_{1} = 461.1 ml =  0.0004611 m^{3}

Final temperature T_{2} = - 95.8 ° c = 177.2 K

Finial pressure P_{2} = 411 atm = 41644.6 K PA

We know that

P_{1} \frac{V_{1} }{T_{1} }  = P_{2} \frac{V_{2} }{T_{2} }

Put all the values in the above equation

⇒ 835 × \frac{0.0004611}{323.1} = 41644.6 × \frac{V_{2} }{177.2}

⇒ V_{2} = 5.07 × 10^{-6} m^{3}

⇒ V_{2} =  5.17 ml

This is the value of final volume inside the vessel.
