2 answers:
Answer : The balanced chemical reaction will be,
Explanation :
Photosynthesis : It is a type of chemical process which occurs in the green plants or the living organisms.
During the photosynthesis process, carbon dioxide reacts with the water in the presence of sunlight to gives product as glucose and oxygen.
In this reaction, carbon dioxide and water molecule are the reactants and glucose and oxygen are the products.
The balanced chemical reaction will be,

The efficiency of the scissor is 200%.
<u>Explanation:</u>
Efficiency is defined as the ratio of output of any instrument or device or machine to the input supplied to it. So the greater the output the greater will be the efficiency of the device.
As here the work done by us on the system is said to be 10 J so this will be equal to the input work done on the system. And the work done by the system i.e., the scissor is 20 J, so this will be the output work.
So, the efficiency is the ratio of output to input as shown below.
Efficiency = = 200
So, the efficiency of the scissor is 200%.
