Zinc Oxide is the IUPAC name for ZnO
The properties of a mineral depend on the kind of atoms of mineral being examined
Answer:
Y = 92.5 %
Explanation:
Hello there!
In this case, since the reaction between lead (II) nitrate and potassium bromide is:

Exhibits a 1:2 mole ratio of the former to the later, we can calculate the moles of lead (II) bromide product to figure out the limiting reactant:

Thus, the limiting reactant is the KBr as it yields the fewest moles of PbBr2 product. Afterwards, we calculate the mass of product by using its molar mass:

And the resulting percent yield:

The law of conservation of energy or first law of thermodynamics
Explanation:
From the context we can infer that Mr. Jones was describing the law of conservation of energy.
According to the law of conservation of energy:
"energy is not created nor destroyed by can be transformed from one form to another" .
The captured energy is a form of energy and it is change into other forms in the ecosystem.
Energy is initially captured in the ecosystem by plants.
