What is the ideal gas constant?
AURORKA [14]

Answer:

Ideal gas constant is a universal constant used for all gases

Explanation:

In Ideal Gases Law, the Ideal gas constant is called R.

It can also be used in Van der Waals equation or, in thermodynamic equations.

R = 0.082 l.atm/mol.K

It is related to the Boltzmann constant, a number that links energy units with temperature units.

25.55 grams of tetraphosphorus decaoxide could be produced by the reaction.

Explanation:

First the balanced chemical reaction of the production of tetraphosphorus decaoxide is to be known.

The chemical equation is

10 KClO3 + 3P4⇒ 3 P4010 + 10 KCl

The number of moles of KCLO3 will be calculated by the formula:

number of moles = mass of the compound given ÷ atomic mass of the compound

n = 37.1 ÷ 122.55     ( atomic mass of KClO3 is 122.55 gm/mole)

   = 0.30 moles

From the stoichiometry

10 moles of KClO3 is required to produce 3 moles of P4O10

when 0.30 moles of KClO3 is used x moles of P4O10 is formed

thus, 3 ÷ 10 = x ÷ 0.30

   = 0.09 moles of KClO3 is produced

To know the mass of P4O10 apply the formula

mass = number of moles × atomic mass

        = 0.09 × 283.886   ( atomic mass of P4O10 is 283.88 gram/mole)

         = 25.55 grams of P4O10 could be produced.
