Answer:
D.) The nuclear model describes the atom as a dense, positive nucleus surrounded by a cloud of negative electrons.
it would be 26 because once you divide 160g by 5.0g and add 12.5 you would get 26
hope this helps
2NaCl + 1CaS →1Na2S + 1CaCl2
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
(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.
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
(s) would be greater in distilled water than in tap water that contains 50 mg/L of calcium ions

Answer:
Theoretical maximum moles of hydroquinone: 0.2167 mol.
Explanation:
Hello,
In this case, the undergoing chemical reaction is like:

In such a way, since the molar mass of quinone is 108.1 g/mol and it is in a 1:1 molar ratio with hydroquinone, we can easily compute the theoretical maximum moles of hydroquinone by stoichiometry:

Clearly, this is the theoretical yield which in grams is:

Which allows us to compute the percent yield as well since the obtained mass of the product is 13.0 g:

Best regards.
