Greenhouse gases released from the burning of fossil fuels are responsible for global warming.
<h3>What is the atmosphere?</h3>
The atmosphere is the region of region of the planet above its surface area where gases envelop the planet.
Based on the effect of greenhouse gases on global warming;
- Planet A has a higher surface temperature due to the higher amount of carbon dioxide in the atmosphere since carbon dioxide is a greenhouse gas.
- Methane is the main constituent of natural gas. Humans increase the contribute to increase in methane gas by raising cattle,
- Pollutants come from both natural sources and human activities.
- Sulfur Dioxide is produced by the combustion of fuels in automobiles. Once in the atmosphere, it combine with water to form acid precipitation.
- Nitrogen and oxygen do not contribute to the greenhouse effect because they are made up of 2 atom molecules that are bound tightly so they CANNOT vibrate to absorb energy.
- Greenhouse gases contribute to global warming by absorbing infrared energy that reflects off Earth's surface and reemitting the energy in all directions. This keeps the infrared energy close to the Earth's surface.
- Most of the greenhouse gases produced come from burning fossil fuels in factories, ships, cars, trains.
Therefore, pollutants such as greenhouse gases are responsible for global warming.

Answer:
Explanation:
CuCO3(s) ====> Cu(ii)O(s) + CO2(g)
Nothing else needs to be done. The equation is balanced.
Bond dissociation energy is inversely proportional to Bond length.
The longer the bond is, lesser the energy it requires to break the bond.
Therefore, it is easier to break single bond.
Single bond>double bond>triple bond -------(Bond length)
Answer:
Answer:
Explanation:
(A) Heavier members of group 1A are usually more reactive than the lighter members e.g. lithium react very slowly with liquid bromine whereas CS react violently.
Similarly Be of group 2A has smaller size, heavier member of this group show different colour in flame test but Be and Mg emit light when heated. Reactivity of group 2A metals decreases down the group
(B) In ethylene polymerization, the stronger catalytic action is shown by the alkyl of metal having less diameter e.g Be, Li etc.
A lithium alkyl in a hydrocarbon solvent is stereospecific catalyst for polymerisation of isoprene
