Answer:
The correct answer is B. causes environmental acidification due to production of sulfuric acid.
Explanation:
Sulphur causes environmental acidification due to production of sulfuric acid. For example,
Sulphur can be oxidized to sulphur dioxide according to the equation:
S +O2 ==> SO2
The sulphur dioxide combines with rain water and is washed down in form of weak acid according to the equation;
SO2 +H2O ==> H2SO3
The product is an acid known as trioxosulphate (V) acid which is a sulphuric acid. And so acidification of environment is possible.
Also as Sulfur can be found in the air in many different forms. It can cause irritations of the eyes and the throat with animals, when the uptake takes place through inhalation of sulfur in the gaseous phase. Sulfur is applied in industries widely and emitted to air, due to the limited possibilities of destruction of the sulfur bonds that are applied.
The damaging effects of sulfur with animals are mostly brain damage, through malfunctioning of the hypothalamus, and damage to the nervous system.
The plant produces oxygen which the animals need (may also be food source), and the animals produce waste products and carbon dioxide which the plants need, so theoratically the system can be left on its own without external support(self sustaining).
Answer:
Find the molar mass of all the elements in the compound in grams per mole.
Find the molecular mass of the entire compound.
Divide the component's molar mass by the entire molecular mass.
You will now have a number between 0 and 1. Multiply it by 100% to get percent composition.
Explanation:
At the core of the sun, it can be more than 27 million degrees Fahrenheit (15 million degrees Celsius).
From the core, energy moves to the radiative zone, where it bounces around for up to 1 million years before moving up to the convective zone, the upper layer of the sun's interior. The temperature here drops below 3.5 million degrees F (2 million degrees C). Large bubbles of hot plasma form a soup of ionized atoms and move upwards to the photosphere.
