Answer:
1. Iron(iii) hydroxide
2. It is a base
Explanation:
To determine the name of the compound, we must find the oxidation number Fe in the compound since the oxidation number of O is —2 in all its compound except for peroxide where it —1 and the oxidation number of Hydrogen is always +1 in all its compounds except for hydrides where it is —1. The oxidation number of Fe can calculated as follows:
Fe(OH)3 = 0
O = —2
H = +1
Fe =?
Fe + 3( —2 + 1) = 0
Fe + 3(—1) = 0
Fe —3 = 0
Fe = 3
The oxidation number of Fe in Fe(OH)3 is 3.
Therefore, the name of Fe(OH)3 is Iron(iii) hydroxide
Fe(OH)3 is a base since it contains the OH group
Answer:
Mutualism is the doctrine that mutual dependence is necessary to social well-being.
Commensalism is an interaction between two organisms living together in more or less intimate association in a relationship in which one benefits and the other is unaffected.
Parasitism is a symbiotic relationship between species, where one organism, the parasite, lives on or inside another organism, the host, causing it some harm, and is adapted structurally to this way of life. The entomologist E. O. Wilson has characterized parasites as "predators that eat prey in units of less than one"

Answer:
8.0 g
Explanation:
To convert moles to grams, you need to use the molar mass. The molar mass of sulfur is 32.06. The molar mass is the atomic mass of the atom.
(0.25 mol) × (32.06 g/mol) = 8.015 g
Round for significant figures.
8.015 g ≈ 8.0 g
