Only the first word in an organism's complete scientific name has its first letter capitalized.
When writing out the organism's scientific name, it goes Genus and then species. The Genus is always capitalized and species is always lowercase. Also when writing the name, usually you either write it in italics or underline the scientific name.
Answer:
Explanation:
Molar ratio for Sg : FeS = 1:8
If there are 0.3 moles for Sg
Therefore, 0.3 × 8 =2.4 moles of FeS
Mass = Moles/ Mr
Mr of FeS = 56+32=88
So mass = 2.4/88
Mass= 0.027g
This is true otherwise cancer patients would have a hole in them and so would the hulk ;)
1) Dalton stated that atom is matter that can not be divided, but it is proved that the atom can be divided into subatomic particles (electrons, protons and neutrons).
2) He stated that atoms of one element can not be changed into atoms of other elements, but now that is possible by nuclear reactions.
Today we still use his postulate: Atoms combine in the ratio of small whole numbers to form stable compounds, for example H₂O.
