It is true that methane, which is a greenhouse gas and contributes to global warming.
A greenhouse gas is a gas that absorbs and emits radiant energy within the thermal infrared range.
Global warming is rise in the average temperature of the Earth's climate system.
Most often greenhouse gases are carbon dioxide (CO2) and methane (molecular formula CH4). These gases come from burning multiple substances: coal, petroleum, plastic and natural gas.
Balanced chemical reaction of combustion of methane:
CH₄ + 2O₂ → CO₂ + 2H₂O
Greenhouse gases are so difficult to measure, because carbone dioxide, methane, chlorofluorocarbons comes from multiple sources, some of which are relatively hard to measure.

Answer:
None of the above
Explanation:
The (−OH) group on phenol can form hydrogen bonds, and the −CH3 group on toluene cannot.
Phenol has only one hydrogen on the −OH group available to form hydrogen bonds, so the hydrogen bond is stronger. In toluene, the hydrogen bond is spread over all three hydrogens on the methyl group, so the interaction is weaker overall.
Phenol has a higher molecular mass than toluene.
Given :
Compared with a mole of oxygen-16, a mole of sulfur-32 contains:
A. twice as many atoms .
B. half as many atoms .
C. an equal number of atoms .
D. 8 times as many atoms .
To Find :
The correct option .
Solution :
One mole of atoms of oxygen-16 has a mass of 16 g, as 16 is the atomic weight of oxygen, and contains 
atoms of oxygen.
Same, one mole of sulfur-32 has 32 g mass , and contains same atoms of sulfur .
So , both have equal number of atoms .
Therefore , option C. is correct .
Hence , this is the required solution .
They are like carried by the convection in the mantle which is pulsing or pushing the plates upwards. the earth kind of "floats" in ways. mostly its just pressure from the mantle and center of the earth pushing the plates upward and out.
Given what we know, we can confirm that mercury sulfide is the mineral that provides the red coloring used by artists for thousands of years.
<h3>What is mercury sulfide?</h3>
This is a compound that can be quite toxic. It has come to be known as Cinnabar. This mineral has a distinct property in which it will provide red coloring, which drew the attention of ancient artists that used it for art and decorations.
Therefore, we can confirm that the mineral known as Cinnabar, which is mercury sulfide, is the mineral that provides the red coloring used by artists for thousands of years.
