Just as a 'dozen' 12 of something, a 'mole' is about 6.02 *10^23 of something. in chemistry, we like to measure the number of atoms or molecules in moles. if one mole is equal to 6.02*10^23 atoms, and you have 7.00 * 10^23 atoms, then how many moles do you have?

6.02*10^23  to 7.00*10^23

You can just cancel out the 10^23 on both sides to make it easier.

6.02 to 7.00

in this case you will divide what you have (7) by what one is equal to (6.02)

7 / 6.02 = 1.16279069767 or approximately 1.163 or 1 and 49/301 or, for the most simplified fraction, 1 and 7/43

when atmosphere interacts with biosphere they focuses on on the sources and sinks of green house gases (ghgs) air pollutants, particular matters, water and energy between the earth's surface and the atmosphere. the biosphere affects the climate. the atmosphere and biosphere are in constant interaction with each other, and all living things rely on gases in the atmosphere for life. organisms such as animals take in oxygen gas form the atmosphere to use in every cell of their body for smooth functioning of daily routine exercises.

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.
