The mass of aluminum that will combine with 16.5 g of oxygen is 75.64 g.  

The mass of aluminum that will combine with 16.5 g of oxygen, we need to first convert the mass of oxygen from grams to moles, since the reaction will occur at a fixed temperature and pressure.

1 mole of oxygen contains [tex]6.022 * 10^{23[/tex] atoms, so 16.5 g of oxygen contains:

16.5 g /  [tex]6.022 * 10^{23[/tex] atoms/mole = 0.00027 moles of oxygen

Next, we need to convert the number of moles of oxygen to moles of aluminum. The equation for the reaction is:

[tex]Al_2O_3 + 3O_2 - > 2Al_2O_3[/tex]

Since we are combining 1 mole of oxygen with 3 moles of aluminum oxide, we can write the equation as:

[tex]16.5 g (O_2) + 3 x 0.00027 mol Al_2O_3 == 2 * 0.00027 (mol) Al_2O_3[/tex]

We can now solve for the mass of aluminum by dividing both sides of the equation by 2 and multiplying by the molar mass of aluminum oxide (44.01 g/mol):

mass of aluminum = (16.5 g O2 x 44.01 g/mol) / (2 x 0.00027 mol)

mass of aluminum = 75.64 g

Therefore, the mass of aluminum that will combine with 16.5 g of oxygen is 75.64 g.

From the following is a secondary protein structure.  b) Alpha-helix  is the correct option.

Secondary protein structure refers to the regular and recurring patterns of hydrogen bonding between the backbone atoms of a protein. These patterns result in the formation of stable structural elements within the protein. Two common examples of secondary structure are alpha-helices and beta-sheets.

An alpha-helix is a right-handed coiled structure where the polypeptide chain forms a spiral-like shape. It is stabilized by intramolecular hydrogen bonds between the carbonyl oxygen of one amino acid residue and the amide hydrogen of an amino acid residue four positions ahead in the sequence. This pattern repeats along the length of the helix.

On the other hand, an epsilon turn (option a) is not a secondary protein structure. It refers to a tight turn in the protein structure involving four amino acid residues. The epsilon turn allows the protein chain to change direction quickly.

Gamma chain (option c) is not a secondary protein structure either. It is commonly used to refer to the gamma chains of hemoglobin, which are subunits of the protein involved in oxygen transport.

Similarly, beta wall (option d) is not a recognized term for a secondary protein structure. It may be a misleading option.

Yes, acetophenone (C6H5COCH3) can be completely deprotonated by lithium diisopropylamide (LDA) under appropriate conditions.

LDA is a strong base commonly used in organic synthesis reactions. It is a powerful non-nucleophilic base that can abstract protons from weakly acidic compounds.

In the case of acetophenone, LDA can deprotonate the alpha carbon adjacent to the carbonyl group. This deprotonation leads to the formation of an enolate ion:

C6H5COCH3 + LDA → C6H5COCH2(-) + LDAH

The resulting enolate ion is stabilized by resonance, and the deprotonation can proceed until all of the alpha protons are removed.

Therefore, in the presence of sufficient LDA, acetophenone can undergo complete deprotonation to form the corresponding enolate ion.

It is important to note that the extent of deprotonation can depend on reaction conditions, such as temperature, concentration, and the stoichiometry of LDA relative to acetophenone.

Additionally, other factors, such as the presence of competing reactions or steric hindrance, may influence the outcome of the deprotonation process.

The energy released in the fusion reaction 14N + 12C + 6Li → 32S can be calculated using the principle of mass-energy equivalence (E=mc²). The energy released is approximately 3.27 x 10⁻²⁰ joules.

To calculate the energy released, we need to determine the mass difference between the reactants and the product.

The total mass of the reactants is:

m(N) + m(C) + m(Li) = 14.00307 amu + 12.00000 amu + 6.01512 amu = 32.01819 amu.

The mass of the product is:

m(S) = 31.97207 amu.

The mass difference (∆m) is given by:

∆m = mass of reactants - mass of product

∆m = 32.01819 amu - 31.97207 amu = 0.04612 amu.

Using the mass-energy equivalence equation E = ∆mc², where c is the speed of light (3 x 10⁸ m/s), we can calculate the energy released:

E = (0.04612 amu) x (1.66 x 10⁻²⁷ kg/amu) x (3 x 10⁸ m/s)²

E ≈ 3.27 x 10⁻²⁰ joules.

The strongest interactions between molecules of ammonia (NH3) are hydrogen bonds.

Ammonia molecules consist of one nitrogen atom bonded to three hydrogen atoms. Each hydrogen atom in ammonia carries a partial positive charge, while the nitrogen atom carries a partial negative charge due to the difference in electronegativity. This charge separation allows ammonia molecules to form hydrogen bonds with other ammonia molecules or with other molecules capable of hydrogen bonding.

Hydrogen bonds are attractive interactions between the partially positive hydrogen atom of one molecule and a lone pair of electrons on a highly electronegative atom, such as nitrogen, oxygen, or fluorine, in another molecule. In the case of ammonia, the lone pair of electrons on the nitrogen atom can form hydrogen bonds with the hydrogen atoms of neighboring ammonia molecules or with other molecules that have hydrogen bond acceptor sites.

These hydrogen bonds between ammonia molecules are stronger than the intermolecular forces observed in many other compounds. They contribute to ammonia's higher boiling point and greater stability compared to other compounds with similar molecular weights.

The water level should then be recorded, and the difference between the initial water level and the water level after adding the sample can be used to calculate the volume of the sample.

Finally, the mass of the sample should be divided by the volume in order to calculate the density of the zinc chloride. The density of the zinc chloride can then be compared to the accepted value to determine if it is accurate.
