Answer:
isotopes, there elements with a diffrent type atomic weight then the original, usally due to a higher amout of neutrons than the original. Some Isotopes are just as useable as the normal versions, but in some cases, such as Uranium, they can be even more radioactive than the original form
33.11 trillion kilometers is equivalent to 3.5 light years
hope this helps :)<span />
Answer: Theoretical yield of 
produced by 8.96 g of S is 33.6 g
Explanation:
To calculate the moles :
The balanced chemical equation is:
According to stoichiometry :
2 moles of 
produce = 3 moles of
Thus 0.28 moles of will produce=
of
Mass of 
Thus theoretical yield of produced by 8.96 g of S is 33.6 g
When pH=7, [H⁺] =10⁻⁷.
When pH=5, [H⁺]=10⁻⁵.
10⁻⁵/10⁻⁷ =10²=100
The level of hydrogen ions increased by factor 100.
6CO2 + 6H2O → C6H12O6 + 6O2
glucose produced = 1/6 x 23.6 = 3.93 moles
