Answer:
You would have 1.96 moles.
Explanation:
You are given 608 grams of calcium phosphate Ca₃(PO₄)₂.
Molar mass (M) is the amount of mass that a substance contains in one mole. This substance can be an element or a compound.
Since the molar mass of the compound Ca₃(PO₄)₂ is 310 g / mole, and taking into account the definition of molar mass, you can apply the following rule of three: if 310 grams of Ca₃(PO₄)₂ are contained in 1 mole, 608 grams of the compound in how many moles are present?

moles= 1.96
<u><em>You would have 1.96 moles.</em></u>
It will take 497.67 years to decay.
What is half-life ?
The duration needed for a quantity to decrease to half of its initial value is known as the half-life. In nuclear physics, the phrase is frequently used to indicate how rapidly unstable atoms decay radioactively or how long stable atoms last. The phrase is also used more broadly to describe any kind of exponential decay (or, very infrequently, nonexponential decay). The biological half-life of medications and other compounds in the human body, for instance, is a term used in the medical sciences. Half-opposite life's in exponential growth is time's doubling.
The formula
At = (Ao)(0.5)(t/h)
where Ao is the initial amount determines the amount of material at a specific time t, At, with a half-life of h.
At/Ao = 0.45 from the stated results in (0.5)(t/432).
T in the equation has a value of 497.67 years.

Answer:
A. They are malleable, ductile, and conduct electricity.
Explanation:
Given what we know, we can confirm that despite not being able to provide a visual representation, if you were to create one, it would show the atoms in the substance moving with <u>more and more </u>energy over time until vaporization occurred.
<h3>What is vaporization?</h3>
- Vaporization is the changing of a liquid into a gas.
- This is known as a phase change.
- This happens when the atoms receive enough heat energy.
- The heat energy provides the atoms with kinetic energy and causes them to move faster over time.
- When the kinetic energy is enough to rupture the bonds that hold a liquid together, it becomes a gas.
Therefore, given that vaporization is when atoms within a substance gain so much kinetic energy that they are able to rupture the bonds that hold them relatively close together and change into a gas, we can confirm that a visual representation would have to be a diagram showing the increased movement of atoms over time.
