pioneer species. because they are flower like species
Answer:
207.89g
Explanation:
The formula of the compound is:
Fe₂S₃
Find the molar mass of the compound;
Atomic mass of Fe = 55.845g/mol
S = 32.065g/mol
Now;
Molar mass of Fe₂S₃ = 2 (55.845) + 3 (32.065)
= 207.89g
There are 5 valence electrons in a atom of phosphorus.
That force would be gravity. Gravity is what pulls any object down towards Earth due to the large mass of the Earth.
Because zinc is above lead on the activity series. This means that in a single displacement reaction such as this one, Pb will not easily displace Zn.
