If there is more soil, there would be more plants, and thus, more organisms, depending on if the soil has enough nutrients to support an ecosystem. The way that this would affect the climate is that it would transpire moisture into the atmosphere, and also generate fresher air through photosynthesis.
The gram-formula mass of Sm is 150.36 u, and the gram-formula mass of O is 15.999 u, so the gram-formula mass of SmO is about 150.36+15.999 = 160.36 g/mol.
So, there are about (9.30 * 10^-3)(160.36)=1.49 grams
Answer:
Graphite and diamond are two of the most interesting minerals. They are identical chemically – both are composed of carbon (C), but physically, they are very different. Minerals that have the same chemistry but different crystal structures are called polymorphs.
One chemical property would be reactivity of a particular substance.
Answer:
1.6 × 10²³ molecules of N2O5
Explanation:
To find the amount of molecules from the amount of moles of a substance we simply multiply the amount of moles by Avagadro's number.
0.27mol × 6.02×10²³ = 1.6 × 10²³ molecules of N2O5
