How would an apple, potato, and onion all taste the same?

Chemistry

1 answer:

Firlakuza [10]2 years ago

Answer:

If you were to plug your nose, it would block out more than 80% of taste, causing all three items to have no taste- therefore making them taste the same.

The sum of pH and pOH for any aqueous solution equals .

Vsevolod [243]

Answer:

pH is calculated by taking negative logarithm of hydrogen ion concentration. Acids have pH ranging from 1 to 6.9, bases have pH ranging from 7.1 to 14 and neutral solutions have pH equal to 7. Thus the sum of pH and pOH is 14

When a piece of sodium metal is kept in water in chemical equation

jekas [21]

Explanation:

Sodium metal reacts rapidly with water to form a colourless basic solution of sodium hydroxide (NaOH) and hydrogen gas (H2). The reaction continues even when the solution becomes basic. The resulting solution is basic because of the dissolved hydroxide.

What do we assume about the volume of the actual molecules themselves in a sample of gas, compared to the bulk volume of the gas

Firlakuza [10]

We assume that the volume of the molecules themselves in a gas sample is negligible compared to the bulk volume of the gas sample: this helps us to explain why gases are so compressible.

Indicate the peptides that would result from cleavage by the indicated reagent: a. Gly-Lys-Leu-Ala-Cys-Arg-Ala-Phe by trypsin b.

Ilia_Sergeevich [38]

Answer:

a. Gly-Lys + Leu-Ala-Cys-Arg + Ala-Phe

b. Glu-Ala-Phe + Gly-Ala-Tyr

Explanation:

In this case, we have to remember which peptidic bonds can break each protease:

-) Trypsin

It breaks selectively the peptidic bond in the carbonyl group of lysine or arginine.

-) Chymotrypsin

It breaks selectively the peptidic bond in the carbonyl group of phenylalanine, tryptophan, or tyrosine.

With this in mind in "peptide a", the peptidic bonds that would be broken are the ones in the "Lis" and "Arg" (See figure 1).

In "peptide b", the peptidic bond that would be broken is the one in the "Phe" (See figure 2). The second amino acid that can be broken is tyrosine, but this amino acid is placed in the C terminal spot, therefore will not be involved in the hydrolysis.

Which of the subshells below do not exist due to the constraints upon the angular momentum quantum number?A) 2dB) 2sC) 2pD) all

Gnom [1K]

Answer:

Option A): Due to the constraints upton the angular momentum quantum number, the subshell 2d does not exist.

Explanation:

The angular momentum quantum number, identified with the letter l (lowercase L), number is the second quantum number.

This number identifies the shape of the orbital or kind of subshell.

The possible values of the angular momentum quantum number, l, are constrained by the value of the principal quantum number n: l can take values from 0 to n - 1.

So, you can use this guide:

Principal quantum Angular momentum Shape of the orbital

number, n quantum number, l

1 0 s

2 0, 1 s, p

3 0, 1, 2 s, p, d

Hence,

the subshell 2d (n = 2, l = 2) is not feasible.

2s (option B) is possible: n = 2, l = 0

2p (option C) is possible: n = 2, l = 1
