<u>Answer:</u> The percentage yield of 
is 90.26%.
<u>Explanation:</u>
The number of moles is defined as the ratio of the mass of a substance to its molar mass. The equation used is:
......(1)
Given mass of 
= 80 g
Molar mass of = 100 g/mol
Plugging values in equation 1:
For the given chemical equation:
By the stoichiometry of the reaction:
If 1 mole of produces 1 mole of
So, 0.8 moles of will produce = 
of
Molar mass of = 44 g/mol
Plugging values in equation 1:
The percent yield of a reaction is calculated by using an equation:
......(2)
Given values:
Actual value of = 35.2 g
Theoretical value of 
= 39 g
Plugging values in equation 2:
Hence, the percentage yield of is 90.26%.

Answer:
Ammonium bromide can be prepared by the direct action of hydrogen bromide on ammonia. It can also be prepared by the reaction of ammonia with iron(II) bromide or iron(III) bromide, which may be obtained by passing aqueous bromine solution over iron filings.

Answer:
The two samples have identical properties because they are the samples of the same element. Intensive properties are properties of matter that do not change depending on the amount of matter. Luster, reactivity, and ductility are all intensive properties. That is why the two samples can be different sizes or shapes, but have identical properties.
