Answer:
Explanation:
As the bacteria are capable of surviving in the hot temperatures as thermophiles they can speed up their respiration rate and hence, will produce more carbon dioxide and potentially accelerating the climate change within a region. The other prokaryotes can also become the significant contributors of the carbon output and these are those which are highly sensitive to the temperature. Methane oxidizing bacteria are also responsible for the contribution in carbon and nitrogen cycles. These bacteria converts the important greenhouse gas methane into carbon and nitrogen compounds like CO2 and NO2 − respectively. Thus methane can be considered as precursor of the temperature rise.
The balanced chemical equation for the reaction between copper(II) sulfate and ammonium sulfide is CuSO4 + (NH4)2S → CuS + (NH4)2SO4.
The balanced chemical equation for the reaction between copper(II) sulfate and ammonium sulfide is:
CuSO4 + (NH4)2S → CuS + (NH4)2SO4
This equation shows that when copper(II) sulfate (CuSO4) reacts with ammonium sulfide ((NH4)2S), copper(II) sulfide (CuS) and ammonium sulfate ((NH4)2SO4) are formed.

The chemical reaction between copper(II) sulfate and ammonium sulfide producing copper(II) sulfide and ammonium sulfate is balanced when written as CuSO4 + (NH4)2S → CuS + (NH4)2SO4. This adheres to the principle of conservation of mass, ensuring an equal number of each type of atom on both sides.
The balancing chemical equation in question, copper(II)sulfate + ammonium sulfide = copper(II) sulfide + ammonium sulfate, starts off with the substances copper(II) sulfate and ammonium sulfide on the left side of the equation. In the process being described, these compounds engage in a chemical reaction, resulting in the formation of new substances, copper(II) sulfide and ammonium sulfate, which are represented on the right side of the equation. The balanced form of this equation is: CuSO4 + (NH4)2S → CuS + (NH4)2SO4.
An important concept in Chemistry is the principle of conservation of mass, which states that the total mass of substances does not change during a chemical reaction. Therefore, for a chemical equation to be balanced, there must be an equal number of each type of atom on both the left and right sides of the equation.
Applying this to the equation, we have 1 atom of copper (Cu), 1 atom of sulfur (S), 4 atoms of oxygen (O), 2 atoms of nitrogen (N), and 8 atoms of hydrogen (H) on both sides of the equation, which confirms that it is properly balanced.

The substance that combined with the oxygen to form a greenhouse gas has been carbon (C). Thus, option E is correct.
The greenhouse gases have been responsible for the entrapment of the sun's energy in the atmosphere, leading to the increase in the temperature of earth and making earth an appropriate place to live.
The greenhouse gases have been the carbon dioxide, methane, sulfur etc. that are able to entrap the energy.
The reaction of carbon with oxygen has been resulted in the formation of carbon dioxide. It has been a green house gas.
Thus, the substance that combined with the oxygen to form a greenhouse gas has been carbon (C). Thus, option E is correct.

B
It changes direction when it passes through an opening
С
It changes its speed and wavelength when it passes through an opening
D
It changes direction when it passes from one medium to another
E
It changes its speed and wavelength from one medium to another.
F
It changes direction when it bounces off of a solid surface.
If a sound wave refracts,It changes its speed and wavelength when it bounces off of a solid surface,It changes its speed and wavelength when it passes through an opening, and It changes direction when it passes from one medium to another. Therefore, option A, C and D are correct.
An important case in which sound waves change form or spread out is called refraction. This phenomenon affects the bending of a sound wave owing to changes in the wave's speed.
Refraction is the reason ocean waves near a shore parallel to the beach and why glass lenses can be used to focus light waves.
If the air above the earth is warmed than that at the surface, sound will be change shape back downward toward the surface by refraction. Soundpropagates in all directions from a point source.
Thus, option A, C and D are correct.
