1. How many molecules are in 643.21 grams of

Veronika [31]

Answer: Calculate the molar mass of Mg3(PO4)2 in grams per mole or search for a chemical formula or substance.

Missing: 643.21 ‎ Must include: 643.21. A balloon is filled with 36.2 liters of Cl2 gas at STP. How many moles of chlorine gas are inside? Solution: 36.2

Missing: 4.061 ‎Must include: 4.061 .For H2O, there is one atom of oxygen and two atoms of hydrogen. A molecule can be made of only one type of atom. In its stable molecular form, oxygen exists as two atoms and is written O2. to distinguish it from an atom of oxygen molecule of three oxygen atoms, in grams per mole or search for a chemical ... Did you mean to find the molecular weight of one of these similar formulas- 80.34.

A substance that conducts electricity, is malleable, ductile, and has luster would be classified as a A) compound B) element C)

Sati [7]

C. Metal

You can think of aluminum cans foils
They are both malleable (to morph easily)
They both are ductile (to flatten out)
They both have luster (shiny)
And they both conduct electricity.

Discuss why the solubility of CaCO33(s) would be greater in distilled water than in tap water that contains 50 mg/L of calcium i

Neporo4naja [7]

The greater, the ionic property, the greater will be solubility. water is a covalent compound where calcium carbonate is ionic that's why the solubility of $CaCO_{3}$ (s) would be greater.

<h3>What is solubility?</h3>

The capability of a substance, the solvent, to combine with another substance, the solvent, has been known as solubility. Insolubility, or just the solute's inability to create that kind of a solution, would be the opposite attribute.

<h3>How does solubility depend on the ionic compound?</h3>

Ionic chemicals dissolve readily in just about any liquid that has the ability to rupture the ionic link present in them. Since water itself has a stronger ionic bond and is still polar in nature, water disrupts the ionic link by hydrogen bonding. Several other solvents, like kerosene and gasoline, are unable to dissolve the ionic bond.
