3 Physical Properties of Carbon Dioxide

1. Colourless, odourless, tasteless gas.

2. Slightly soluble in water.

3. More dense than air.

3 Chemical Properties of Carbon Dioxide

1. Does not support combustion.

2. Turns limewater from clear to milky.

3. Dissolves in water to form carbonic acid (turns litmus from blue to red)

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.
