The equation of the reaction is:
5Ca(OH)₂ + 3H₃PO₄ ---> Ca₅(PO₄)₃(OH) + 9H₂O.
Based on the data provided, the mass of hydroxyapatite formed is 135.62 g.
<h3>What is
hydroxyapatite ?</h3>
Calcium apatite has the chemical formula Ca5(PO4)3(OH), however it is most commonly written Ca10(PO4)6(OH)2 to indicate that the crystal unit cell consists of two entities. Hydroxyapatite, also known as hydroxylapatite (HA), is a naturally occurring mineral form of calcium apatite. The complex apatite group's hydroxyl endmember is called hydroxyapatite. Fluorapatite or chlorapatite can be created by substituting fluoride, chloride, or carbonate for the OH ion. It forms a hexagonal crystal structure when it crystallizes. Powdered hydroxyapatite is completely white. Apatites that are found in nature can also exhibit colorations that resemble dental fluorosis, such as brown, yellow, or green.
Human bone contains up to 50% by volume and 70% by weight of bone mineral, a modified form of hydroxyapatite.

Explanation:
dont put that as an answer i need point for finals
A model aids in visualizing a molecule and understanding its properties.
In chemistry, models of molecules give us an idea about the arrangement of atoms in the molecules. Usually, the arrangement of atoms in a molecules determines the kind of reactions that the molecule can undergo.
Models are three dimensional representations of what molecules look like. They help us to conceptualize the possible orientation of atoms and groups in the molecule.
Looking at the model of H2SO4, it becomes easier to understand the chemical and physical properties of the compound owing to the arrangement of atoms.

B nonmetals that’s your answer :)
Answer:
See explanation
Explanation:
Number of protons = 28
Number of neutrons = 28
Mass of each proton = 1.007277 amu
Mass of 28 protons = 28 * 1.007277 amu = 28.203756 amu
Mass of each neutron = 1.008665 amu
Mass of 28 neutrons = 28 * 1.008665 amu = 28.24262 amu
mass defect of nickel-56 = 0.4667 amu
Binding energy = Δmc^2
Binding energy = 0.4667 *(3 * 10^8)^2
Binding energy =4.2 * 10^16 J
Binding energy per nucleon = 4.2 * 10^16 J/56
Binding energy per nucleon = 7.5 * 10^14 J
