Answer:
You can react it with water to produce energy-rich hydrogen gas, or with hydrogen to produce useful chemicals, such as hydrocarbons or alcohols. If there were a sustainable, cost-efficient route to transform CO2 to CO, it would benefit society greatly.
Explanation:
Hi
I think a very important thing while working in a scientific laboratory is to have cooperation along with a sense of individual responsibility. There are many times when you are not expert in one scientific technique but your senior or fellow worker is because of his/her prior experience. At that point, the people of laboratory should cooperate with each other in giving some tips regarding performing a specific technique and getting the results with minimum time wastage. This does not mean that you take help from some one without giving them credit.
There should be a lab attendant in every lab who should be consulted for every problem so that he can assign some relevant worker to help you in the work. After you get the help, the attendant should confirm from both persons and keep a log about it which they should appreciate and give a fair credit about inquiries of higher authorities like supervisors.
Another important factor that is important for people is to have a sense of respect for each other. This is important to listen to others without just thinking about our own perspective and our own understanding. This also enables to understand a point from larger view and can help to bring a point in mind which we otherwise might skip.
