The greenhouse gases are carbon dioxide, methane, and nitrous oxide.
The greenhouse effect has been defined as the entrapment of the sun's energy by the gases that result in the earth becoming warmer and a better place to live.
The gases present in the atmosphere that has been able to entrap the heat energy has been termed the greenhouse gases.
The greenhouse gases have been carbon dioxide, methane, and nitrous oxide.

The three nuclides, U-233, U-235, and U-238, are isotopes of uranium because they have the same number of protons per atom and
Answer:
Electrons
Explanation:
Isotopes are atoms which have the same number of protons and electrons but a different number of neutrons. This is also the reason why there are no other changes in the atom but the mass of the specific atom changes.

Merry Christmas. Have fun.
A small container of perfume is opened in a classroom. Soon every student in the room smells the perfume. Explain this in terms of molecules.
When perfume or cologne is sprayed into the air, it turns into a gas and its particles mix with other air particles that quickly move around the room. This is because gas is the least dense of the three states of matter. It moves quickly into any space or volume because it has the least density. This is called diffusion, when molecules or particles move from areas with high concentration to low concentration areas.
The atomic mall mass is an element depends upon the.
Answer:
Mass and relative abundance of each isotope of that element
The atomic mass of element has been dependent on mass of each isotopes and their abundance in nature.
The atomic mass has been the mass of neutrons and protons of the element. There has been the presence of the isotopes of the elements, with varying abundance, and varying atomic masses.
The atomic mass of the element has been the relative average atomic mass of the element with respect to the mass of the isotopes and their percent abundance.
The average atomic mass (amu) has been given by:
[tex]amu=M_1A_1\;+\;M_2A_2[/tex]
Where, [tex]M_1A_1[/tex] has been the atomic mass and abundance of isotope 1.
[tex]M_2A_2[/tex] has been the atomic mass and abundance of isotope 2.
Thus, the average atomic mass has been dependent on mass of each isotopes and their abundance in nature.

Is this an example of an endothermic or exothermic reaction? Why?
Answer:
Explanation:
Exothermic: the surrounds feel warmer. A wood fire stove is a good example of an exothermic reaction. You can feel the heat on your hands. It's exothermic.
Endothermic is exactly the opposite. The reaction takes place, but the heat comes from the surroundings. When you touch something that goes through an endothermic reaction, it feels much cooler.
This reaction, just by definition is endothermic.

A.
the potassium atom will gain an electron and become smaller as a cation, while the barium atom will lose an electron and become bigger as an anion.
B.
the potassium atom will lose an electron and become smaller as an anion, while the barium atom will gain an electron and become bigger as a cation.
C. the potassium atom will gain an electron and become smaller as an anion, while the barium atom will lose an electron and become bigger as a cation.
D.
the potassium atom will lose an electron and become smaller as a cation, while the barium atom will gain an electron and become bigger as an anion.
Answer:
D (But as a heads up, you wrote barium instead of Bromine)
Explanation:
The Potassium atom will lose an electron since its valence shell only has one, while Bromine has 7 electrons in its valence shell. Potassium wants to get rid of its one electron, Bromine wants to gain that one electron to get a full shell.
Potassium will become a CATION with a positive charge (since it lost an electron), Bromine will become an ANION with a negative charge (since it gained an electron)
