Why is melting a physical property of the wax, but flammability is a chemical property?

Chemistry

Fiesta28 [93]3 years ago

Melting is a physical property and a physical change to wax. We know this because although the wax might melt, it will resolidify into its original form. Flammability, however, is a chemical change because the act of burning involves a chemical reaction between the gases in the air and heat, which cannot be reversed.

When she introduced CO(g) and Cl2(g) into a 1.00 L evacuated container, so that the initial partial pressure of CO was 1.86 atm
cupoosta [38]

Answer:

Kp is 0.00177

Explanation:

We state the equilibrium:

CO(g) + Cl₂(g)  ⇆  COCl₂(g)

Initially we have these partial pressures

1.86 atm for CO and 1.27 for chlorine.

During the reaction, x pressure has been converted. As we have 0.823 atm as final pressure in the equilibrium for COCl₂, pressure at equilibrium for CO and chlorine will be:

1.86 - x for CO and 1.27 - x for Cl₂.

And x is the pressure generated for the product, because initially we don't have anything from it. So pressure in equilibrium for the reactants will be:

1.86 - 0.823 = 1.037 atm for CO

1.27 - 0.823 = 0.447 atm for Cl₂

Let's make, expression for Kp:

Partial pressure in eq. for  COCl₂ / P. pressure in eq. for CO . P pressure in eq. for Cl₂

Kp = 0.823 / (1.037 .  0.447) → 0.00177

The gas in a balloon has a volume of 7.5 L at 100, kPa. The balloon is released into
erik [133]

Answer:

please rate my answer 5 Star

Explanation:

Using Boyle's Law,

The pressure exerted by a gas is inversely proportional to the volume the gas is occupying provided the temperature is constant

p*v = constant

100*1000*7.5 = p * 11

p = 750000/11
