It is like an idea that they come up with in an experimeant
In a redox reaction electrons are lost and gained in equal numbers. The species that is oxidized gives electrons to the species that is reduced. I hope this helps. Let me know if anything is unclear.
Burning fossil fuels release a lot of carbon dioxide which is a greenhouse gas which contributes to global warming. Also burning of fossil fuels causes a lot of air pollution. You can also describe in detail the effect of carbon dioxide on global warming in general
Answer:
C) Subtract the number of protons from mass number.
Explanation:
An atom consist of electron, protons and neutrons. Protons and neutrons are present with in nucleus while the electrons are present out side the nucleus.
All these three subatomic particles construct an atom. A neutral atom have equal number of proton and electron. In other words we can say that negative and positive charges are equal in magnitude and cancel the each other. For example if neutral atom has 6 protons than it must have 6 electrons. The sum of neutrons and protons is the mass number of an atom while the number of protons are number of electrons is the atomic number of an atom.
For example
The carbon have six protons and six neutrons so its atomic mass is 12 amu and atomic number is six.
Number of neutrons = mass number - number of protons
Number of neutrons =12 - 6
Number of neutrons = 6
Answer:
1 year- 1 mole
time in general- amount of matter
1 second- 1 atom/ particle
