Which of the following tasks might they ask a
chemist to do? Explain your answer.
a. Determine the materials used to make the pots.
b. Explain what the designs on the pots represent.
c. Recommend how to store the pots to prevent
further damage.
Answer:
a. Determine the materials used to make the pots.
Explanation:
Workers digging a tunnel through a city who find some ancient pots decorated with geometric designs will employ the services of a chemist.
The chemist would help to determine the materials which were used to make the pots . This is usually done by various type of experiments and observations. After the constituent of the pot is gotten then more information would be derived from the possible source and use of the pot
2: Chlorine free radicals are produced in the upper atmosphere when ultraviolet radiation interacts with chlorofluorocarbons (CHCs). The free radicals catalyze the conversion of ozone to oxygen. How is this catalysis harmful to humans
1. By using less energy, reactions that are catalysed are also more sustainable, and therefore better for the environment.
2. By catalysing the conversion of ozone into oxygen, the ozone layer sees a reduction, also reducing the amount of protection from direct UV rays given to humans and other forms of life by the ozone layer.
b. 3d
c. 3s
d. 2f
