See Below for answer!
Explanation:
In order to find the number of orbitals given the principal quantum number, n, we can use . For example n=2 would have 8 orbitals.
A) 32
B) 98
C) 50
D) 18
<h3>Mass of glucose : 6.7356 kg</h3><h3>Further explanation
</h3>
Solution properties are the properties of a solution that don't depend on the type of solute but only on the concentration of the solute.
Solutions from volatile substances have a higher boiling point and lower freezing points than the solvent
For freezing point can be formulated
K = molal freezing point constant
m = molal solution
A solution with a freezing point of -5.8 ∘C
The balanced chemical equation would be as follows:
<span>AlCl3(aq) + 3AgC2H3O2(aq) -> 3AgCl(s) + Al(C2H3O2)3(aq)
</span>
We are given the concentrations of the reactants. We use these values to calculate for the volume of aluminum chloride needed. We do as follows:
0.500 mol/L AgC2H3O2 (0.020 L) ( 1 mol AlCl3 / 3 mol AgC2H3O2 ) ( 1 L / 0.250 AlCl3 ) = 0.0133 L or 13.3 mL of AlCl3 solution is needed
<h3><u>Compare and contrast between bonds and molecules of polar and non-polar:</u></h3>
- Non-polar covalent bonds are a type of covalent bond in which a pair of electrons is shared with each other between two atoms.
- Polar covalent bond is a type of covalent bond in which pair of electrons are not equally shared between two atoms. We can also say bonds are polar when one element in a compound is more electronegative than the other.
- The bond shared in the compound of carbon dioxide between carbon and oxygen atoms is non-polar covalent bond whereas the shared in the compound of water between hydrogen and oxygen atom is polar-covalent bond.
- Polar molecules are those molecules where there is an “electronegativity difference between the bonded atoms”.
- For eg: Water - , Ammonia - , Sulfur dioxide - , Hydrogen sulfide - , Ethanol - , etc.
- Non-polar molecules are those molecules sharing equal electrons between “atoms of a diatomic molecule” or large molecule cancel each other.
- For eg: Carbon dioxide - , Benzene - , Carbon tetrachloride - , Methane - , Ethylene - , etc.
This problem is asking for the for pH when a solution of potassium hydroxide is diluted to the double of its initial volume. Thus, the answer turns out to be 11.0.
<h3>pH calculations</h3>
In chemistry, pH calculations are performed based on the following equation relating the pH and the concentration of hydrogen ions in the solution:
However, since this problem involves a strong base, KOH as potassium hydroxide, one must calculate the pOH instead, and then convert it to pH with the following equations:
In addition, due to the fact it is diluted from 10. mL to 20. mL (with the 10. mL of added distilled water), one needs to use the dilution equation in order to calculate the correct concentration of KOH:
Hence, the pOH turns out to be:
And thereby the pH:
