Answer:

The answer is: A. Photosynthesis

Explanation:

The options B,D and E are examples of exothermic reactions.

An exothermic reaction is a chemical reaction that releases energy to the enviroment.

Option C is an example of the transformation of energy (in this case, chemical energy to electric energy)

Now, the option A  mentions the photosyntesis process.

Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy. Plants take carbon dioxide from the air and water from the soil, and with help of proteins called reaction centres that contain green chlorophyll pigments, the plants can absorb light energy , and transform this elements to sugars and oxygen.

The sugars store the light energy absorbed in the form of chemical energy, in order to be used for the plant energy necessities, and the oxygen is released to the air.

A gas occupies a volume at 34.2 mL at a temperature of 15.0 C and a pressure of 800.0 torr. What will be the volume of this gas
Grace [21]
The answer is 34.1 mL.
Solution:
Assuming ideal behavior of gases, we can use the universal gas law equation
     P1V1/T1 = P2V2/T2
The terms with subscripts of one represent the given initial values while for terms with subscripts of two represent the standard states which is the final condition.
At STP, P2 is 760.0torr and T2 is 0°C or 273.15K. Substituting the values to the ideal gas expression, we can now calculate for the volume V2 of the gas at STP:
     (800.0torr * 34.2mL) / 288.15K = (760.0torr * V2) / 273.15K
     V2 = (800.0torr * 34.2mL * 273.15K) / (288.15K * 760.0torr)
     V2 = 34.1 mL
