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.

romanna [79]

The extent of sewage treatment required mostly depends on the control of suspended solids and BOD of the sewage. Hence, option C is correct.

<h3>What is Inorganic matter?</h3>

Inorganic matter is substances of mineral origin that are not characterized by primarily carbon-based structures.

Sewage treatment (or domestic wastewater treatment, municipal wastewater treatment) is a type of wastewater treatment which aims to remove contaminants from sewage to produce an effluent that is suitable for discharge to the surrounding environment or an intended reuse application, thereby preventing water pollution from raw sewage discharges.

The main goal of wastewater treatment facilities is to protect humans and the ecosystem from harmful and toxic elements found in wastewater.

Hence, option C is correct.

Fill in the coefficients that will balance the following reaction a0h2so4 + a1koh → a2k2so4 + a3hoh
Anuta_ua [19.1K]
A0 = 1
a1 = 2
a2 = 1
a3 = 2

This can be solved by guessing and checking and making sure that all atoms on the left side are accounted for on the right side. Both sides must have the same amount of atoms or the balancing is not correct.
