I don't know sorry I really need point
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.

False. Alkaline earth metals react with oxygen.
Explanation:
chromatoghraphy is a laboratory technique for the separation of mixture... ...
chromatoghraphy may be preparative or analytical. The purpose of preparative chromatoghraphy is to separate the components of a mixture for late use, ans is thus a form of purification..... I is your answer it may help you
Answer:
Einsteinium is heavier
Explanation:
Atomic weight is what we are referring to when figuring out how heavy an element is and is measured in amu (atomic mass units)
(This is also the same as the molar mass how heavy 6.022 x 10^23 atoms of a substance or element is which is measured in grams)
The atomic weight of an element can be found on a periodic table.
Europium has an atomic mass of approximately 152 amu (atomic mass units)
Einsteinium has an atomic mass of approximately 252 amu.
Einsteinium has a higher atomic weight so it's heavier.
There's another easier way of going about it where you don't even have to think about the actual number and basically just look at the element's atomic number and position on the periodic table.
Eu is 63
Es is 99
As the atomic number increases on the periodic table this means it's number of protons is greater.
Protons lie in the nucleus which has most of the atom's weight so the more protons the heavier it is.
Einsteinium has a higher atomic number meaning it has more protons so we can assume it's the heavier one.
Hope this helps!
