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:
The atomic number tells us how many protons and electrons are in the element we are looking at.
Answer:
The amount of electric power produced for each unit of thermal power gives the plant its thermal efficiency, and due to the second law of thermodynamics there is an upper limit to how efficient these plants can be.
Answer:
SiO2
Explanation:
'Si' is the label given to silicon on the periodic table.
Answer:
Density, melting point. and magnetic properties
Explanation:
I can think of three ways.
1. Density
The density of Cu₂S is 5.6 g/cm³; that of CuS is 4.76 g/cm³.
It should be possible to distinguish these even with high school equipment.
2. Melting point
Cu₂S melts at 1130 °C (yellowish-red); CuS decomposes at 500 °C (faint red).
A Bunsen burner can easily reach these temperatures.
3. Magnetic properties
You can use a Gouy balance to measure the magnetic susceptibilities.
In Cu₂S the Cu⁺ ion has a d¹⁰ electron configuration, so all the electrons are paired and the solid is diamagnetic.
In CuS the Cu²⁺ ion has a d⁹ electron configuration, so all there is an unpaired electron and the solid is paramagnetic.
A sample of Cu₂S will be repelled by the magnetic field and show a decrease in weight.
A sample of CuS will be attracted by the magnetic field and show an increase in weight.
In the picture below, you can see the sample partially suspended between the poles of an electromagnet.
