Answer:
How do we know what the temperature of the Earth was in the past? - One way to measure past temperatures is to study ice cores. Whenever snow falls, small bubbles filled with atmospheric gases get trapped within it. In some places, so much snow falls that the older layers become buried and compressed into ice, locking away air bubbles in ice sheets and glaciers
What is the relationship between CO2 (carbon dioxide) and temperature on Earth? - When the carbon dioxide concentration goes up, temperature goes up. When the carbon dioxide concentration goes down, temperature goes down.
What is the greenhouse effect? - the trapping of the sun's warmth in a planet's lower atmosphere, due to the greater transparency of the atmosphere to visible radiation from the sun than to infrared radiation emitted from the planet's surface.
Why are global sea levels rising? - Global warming is causing global mean sea level to rise in two ways. First, glaciers and ice sheets worldwide are melting and adding water to the ocean. Second, the volume of the ocean is expanding as the water warms.

Answer: xx xx
xxOxxCxxSxx
Explanation:
Sorry for the structure, but since Oxygen and Sulfur belong to group of six they want to share two electrons. Carbon belonging to group four wants to share 4 since its valence shell has four electrons.
Therefore the resulting Lewis structure is linear (like carbon dioxide) with two pairs of lone pairs in each O and S atoms and 0 lone pairs in carbon and two double bond.
Answer:
CH4+2O2→CO2+2H2O
Moles of oxygen=3232=1
Moles of carbon dioxide=4422=0.5
Moles of water=1818=1
1 mole of methane reacts with 2 moles of oxygen to give 1 mole of CO2 and 2 moles of water so 0.5 mole of methane will be required which is equal to 0.5×16=8g.
Explanation:
8g
