Answer:

A charge of -3

Explanation:

If you look on a periodic table you will find that phosphorus is 3 elements away from the nearest noble gas argon. This means that phosphorus would prefer a charge of -3!

Answer:typically it will be -3

Explanation:

It prefers to take up 3 electrons and thereby become phosphide with a -3 charge. since it is a nonmetal it will take up electrons making it negative as an ion. In order to fill up its last shell, to become stable, to form an octet it will need 3 added electrons which will give it that -3 charge. An atom of phophorus will be neutral, An ion of phsphorus will have a -3 charge.

Once ____________ bonds form between every fourth amino acid in a polypeptide chain, the chain begins to twist into the ________

AlladinOne [14]

Once hydrogen bonds form between every fourth amino acid in a polypeptide chain, the chain begins to twist into the secondary structure known as a(n) alpha helix.

<h3>What is Amino Acid ? </h3>

Amino acids are organic compound. Amino acids contains amine and carboxyl functional group. Amino acids is the building block of life these are the molecules that combine to form proteins.

<h3>What is Polypeptide Chain ? </h3>

A unique sequence of amino acids joined by peptide bonds is called polypeptide.

Thus from the above conclusion we can say that Once hydrogen bonds form between every fourth amino acid in a polypeptide chain, the chain begins to twist into the secondary structure known as a(n) alpha helix.

Which of the following molecules is the primary product of photosystem I?a) Carbon dioxideb) Oxygenc) NADPHd) ATP

Lina20 [59]

Answer:

The primary product of the photosystem I is NADPH.

Explanation:

NADPH is the acronym of Nicotinamide adenine Dinucleotide Phosphate. This NADPH plays a vital role in many chemical reactions that take place during photosynthesis process. NADPH is released as a product in Photosystem I.

In the photosystem I process, the molecule present will absorb sunlight energy and transfers it to electrons to produce NADPH. This NADPH molecule is used as fuel for the chemical process that occurs during the 2nd stage of the photosynthesis process. Its molecular formula is $C_{12} H_{30} N_{7} O_{17} P_{13}$ . It acts as a fundamental metabolite.

How much NaCl would you dissolve and dilute to the 100.00 mL mark in a volumetric flask with DI H2O to prepare a 0.825 M sodium

adoni [48]

Answer:

4.82 g

Explanation:

To solve this problem we'll use the definition of molarity:

Molarity = moles / liters

We are given the volume and concentration (keep in mind that 100mL=0.100L):

0.825 M = moles / 0.100 L

Now we calculate the number of NaCl moles required:

moles = 0.0825 mol

Then we convert 0.0825 NaCl moles into grams, using its molar mass:

0.0825 mol * 58.44 g/mol = 4.82 g
