It begins with heating of phenol and formaldehyde in the presence of a catalyst such as hydrochloric acid, zinc chloride, or the base ammonia. This creates a liquid condensation product, referred to as Bakelite A, which is soluble in alcohol, acetone, or additional phenol.

Fill in the coefficients that will balance the following reaction:
vfiekz [6]

6NaC₂H₃O₂   +  Fe₂O₃   →   2Fe(C₂H₃O₂)₃  +  3Na₂O

Explanation:

Given equation;

      NaC₂H₃O₂   +  Fe₂O₃   →   Fe(C₂H₃O₂)₃  +  Na₂O

To find the coefficient that will balance this we equation, let us set up simple mathematical algebraic expressions that we can readily solve.

Let us have at the back of our mind that, in every chemical reaction, the number of atom is usually conserved.

      aNaC₂H₃O₂   +  bFe₂O₃   →   cFe(C₂H₃O₂)₃  +  dNa₂O

a, b, c and d are the coefficients that  will balance the equation.

 conserving Na;    a  = 2d

                       C:     2a  = 6c

                       H:     3a  = 9c

                       O;      2a + 3b  = 6c + d

                       Fe:     2b = c

let a = 1

    solving:

      2a = 6c

       2(1) = 6c

          c = \frac{2}{6}  = \frac{1}{3}

      2b = c

          b = \frac{1}{2}  x \frac{1}{3} = \frac{1}{6}

     d = 2a + 3b - 6c = 2(1 ) + (3 x\frac{1}{6}  )  - (6  x  \frac{1}{3}) = \frac{1}{2}

Now multiply through by 6

  a = 6, b = 1, c = 2 and d = 3

             

                6NaC₂H₃O₂   +  Fe₂O₃   →   2Fe(C₂H₃O₂)₃  +  3Na₂O

Which state of matter consists of particles that can be partially compressed? Gas Liquid Plasma Solid
son4ous [18]

Answer: Option (b) is the correct answer.

Explanation:

In liquid state, particles do have kinetic energy that helps in partially overcoming the intermolecular forces between the molecules. But still the particles are close together and they are able to slide past each other.

So, when we apply pressure on a liquid then its molecules partially gets compressed.

On the other hand, molecules of a solid are held together by strong intermolecular forces of attraction. Hence, they have definite shape and volume. As a result, solids do not get compressed.

In gases and plasma state of matter, molecules are gar away from each other. So, they are able to get completely compressed when a pressure is applied.

Thus, we can conclude that liquid is the state of matter which consists of particles that can be partially compressed.
