Option C: Introducing sewage in water systems increases the concentration of solids.

Sewage is one of the most concerning sources of water pollution. Sewage, in simple terms, is the wastewater that contains compostable materials from the kitchen, industries, bathrooms, etc.

When untreated sewage is introduced into the water bodies, the microorganisms in it take up the oxygen from water for their aerobic respiration. As a result, the resident organisms of the water body have to struggle to survive due to the lack of oxygen in the water.

Sewage also contributes to the eutrophication of water bodies. Eutrophication is the process by which the nutritional elements, like phosphates and nitrates, in a water body, are enhanced causing the microorganisms to feast over them.

Sewage has some solid particles that can't be dissolved or decomposed. This then leads to the concentration of solids at the base of the water body. This further leads to the growth of various organisms using dissolved oxygen and leads to the deterioration of water quality.

Naddika [18.5K]

Answer:

The more polar bond is C-O.

Explanation:

The greater polarity is due to that the Oxygen atom is more electronegative than the Nitrogen atom, so the negativity of the molecule tends to be on that side.

The Sun is a yellow star that's both average in brightness and temperature and is classified as
Roman55 [17]

Answer:

Classifying stars according to their spectrum is a very powerful way to begin to understand how they work.  As we said last time, the spectral sequence O, B, A, F, G, K, M is a temperature sequence, with the hottest stars being of type O (surface temperatures 30,000-40,000 K), and the coolest stars being of type M (surface temperatures around 3,000 K).  Because hot stars are blue, and cool stars are red, the temperature sequence is also a color sequence.  It is sometimes helpful, though, to classify objects according to two different properties.  Let's say we try to classify stars according to their apparent brightness, also.  We could make a plot with color on one axis, and apparent brightness on the other axis, like this:

Which of the following gases experience the greatest degree of deviation from ideal behavior under high pressures and low temper
xz_007 [3.2K]

A) CH4

In general, methane reactions are difficult to control. Partial oxidation to methanol, for example, is a rather difficult reaction because the chemical reactions that occur continue to form carbon dioxide and water even though the amount of oxygen available is insufficient.

<h2>Further explanation </h2>

Methane is the simplest hydrocarbon in the form of gas with the chemical formula CH4. Pure methane does not smell, but if used for commercial purposes, a bit of sulfur is usually added to detect leaks that might occur.

Methane is a greenhouse gas. Methane is used in chemical industrial processes and can be transported as frozen liquids (liquefied natural gas, or LNG).

Methane is a major component of natural gas, around 87% of volume.

Methane is not toxic, but is highly flammable and can cause explosions when mixed with air.
