The practical examples i would suggest are:
Try pouring palm oil into a container when thick and when heated, when heated the viscosity is higher than when cooled
Try starting your car in winter and summer, during the winter the viscosity of the engine oil is very high making it difficult for the car to start but reverse is the case during summer
Chlorophyll is the answer
I think we need more information
The balanced chemical reaction is:
<span>2 I2 + KIO3 + 6 HCl ---------> 5 ICl + KCl + 3 H2O
</span>
We are given the amount of the product to be produced from the reaction. This will be the starting point of our calculations.
28.6 g ICl (1 mol / 162.35 g ICl ) ( 2 mol I2 / 5 mol ICl ) ( 253.81 g I2 / 1 mol I2 ) = 17.88 g I2
