Answer:

Number of proton is 11

Number of neutrons is 12

Number of electrons is 10

Explanation:

For a neutral Na, Sodium atom:

The mass number P+N = 23

Atomic number(E or P) = 11

A charged Na atom that has lost an electron is positively charged and so:

Number of proton = 11 (Still the same)

Number of neutrons = 12

Number of electrons = 11-1=10 (the atom has lost an electron)

If an atom loses electron, it becomes positively charged ie P>E

Answer:

It contains 11 protons in the nucleus.

It contains 12 neutrons in the nucleus.

It contains 10 electrons surrounding the nucleus.

The number of electrons are calculated from net charge and charge of proton (+1) and electron (–1).

12 neutrons are calculated from atomic number: 11 and mass number: 23.

I NEED HELP ASAP!!! THIS IS A 30 POINT QUESTION!!!
bekas [8.4K]

Answer:

4

Explanation:

Protein synthesis involves two major steps:

  1. <em>Transcription of the DNA to mRNA (a form of RNA)</em>
  2. <em>Translation of the mRNA molecule into a protein.</em>

<em></em>

Transcription involves the formation of a nucleotide sequence complementary to the DNA molecule, with the pairing of a different base, Uracil, with Guanine instead of the usual Thymine base. This occurs in the nucleus of the cell, and the resulting molecule is known as the mRNA.

This mRNA is transported into the cytoplasm through the nuclear pore for the next step, translation. This is primarily accomplished by ribosomes and tRNA molecules which are present in the cytoplasm of the cell. The result of this step is the generation of a protein molecule.

A chemical process dissolves 500 milligrams of iron oxide every 20 minutes. How long would it take this reaction to dissolve 2 l
stiv31 [10]

Answer:

36290 min = 604.8 hr.

Explanation:

  • Knowing that:

1 lbs = 453.59237 grams.

∴ 2 lbs = 907.18474 grams.

<em><u>Using cross multiplication:</u></em>

500 mg of iron oxide dissolved → 20 minutes.

907184.74 mg of iron oxide dissolved → ??? minutes.

<em>∴ The time needed to dissolve 2 lbs of iron oxide =</em> (907184.74 mg)(20 min)/(500 mg) = <em>36290 min = 604.8 hr.</em>
