Explanation:

This problem deals with balancing of chemical equations.

   Every chemical equations obey the law of conservation of matter which states that "in chemical reactions, matter is usually conserved and are not produced, they are simply recombined".

  Equation of reaction:

      BaO₂   +   H₂SO₄  ⇒  H₂O₂  +  BaSO₄

Let us use a mathematical approach to balance this equation by setting up simple algebraic equations:

        aBaO₂   +   bH₂SO₄  ⇒  cH₂O₂  +  dBaSO₄

a, b, c and d are the number of moles that will balance the equation;

 Conserving Ba:   a = d

                       O:   2a + 4b = 2c + 4d

                        H:    2b = 2c

                         S:    b  = d

now let a = 1

              d = 1

               b = 1

                c  = 1

we see that the equation is already balanced

At 189k a sample of gas has a volume of 32.0cm. what does the gas occupy at 242k
sattari [20]
<h2>Answer:</h2>

At 189 K volume = 32.0 cm

As volume of gas is directly proportional to temperature.

As the temperature increase the volume of gas will also increase.

so

Volume at 1 K =  32/189

Volume at 242 K = 32/189 * 242 = 40.97 cm.

Gas occupy 40.97 cm volume at 242 K.
