Answer:
Explanation:
Let suppose that air inside the tire behaves ideally. The equation of state for ideal gases is:
As tire can be modelled as a closed and rigid container, there are no changes in volume and number of moles. Hence, the following relationship is constructed:
The final pressure is:
Answer:
Explanation:
The reaction only takes place if the reactants are in contact, then the surface exposed is very important because as the exposed surface of the reactants increases, the reaction velocity also increases. If the lumps are not broken up, a big amount of baking soda would be only available to react after the surrounding soda has already reacted.
A Polymer is a substance which has a molecular structure built up mainly or completely from a large number of similar units bonded together, e.g. Many synthetic organic materials used as plastics and resins.
