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
hey there!:
2HgO (s) => 2Hg (l) + O2 (g)
2 moles of HgO decompose to form 2 moles of Hg and 1 mole of O2 according to the reaction mentioned in the question.
So 4.00 moles of HgO must give 4 moles of Hg and 2 moles of O2 theoretically.
603 g of Hg = 603 / 200.6 = 3 moles
Percent yield = ( actual yield / theoretical yield) * 100
= ( 3/4) * 100
= 75 %
Hope this helps!
Answer: explained below
Explanation:
Matter can change form through physical and chemical changes, but through any of these changes, matter is conserved. The same amount of matter exists before and after the change—none is created or destroyed.
