Phosphorus has an electron configuration of [Ne} 3s2 3p3. Phosphorus has 9 electrons in the p orbital.
alekssr [168]3 years ago

Answer:

9 p-electrons

Explanation:

Phosphorus is a reactive chemical element that belongs to the group 15 and period 3 of the periodic table. It is a p-block element having atomic number 15.

The <u>electronic configuration of phosphorus in the ground state </u>is 1s² 2s² 2p⁶ 3s² 3p³.

Since, <u>6 electrons are present in the 2p subshell and 3 electrons are present in the 3p subshell.</u>

<u>Therefore, there are total </u><u>9 p-electrons</u><u> in a phosphorus atom present in its ground state.</u>

The sodium isotope with 13 neutrons. Express your answer as an isotope
wariber [46]

Answer:

          \large\boxed{\large\boxed{^{24}_{11}Na}}

Explanation:

The question is asking to write the <em>isotopic symbol </em>of the form ^A_ZX for the <em>sodium isotope with 13 neutrons</em>.

In general, the isotopic symbol in the given form shows:

  • The element's chemical symbol: X

  • A: mass number of the isotope, written as a superscript to the left of the element's simbol, and

        A = number of protons + number of neutrons

  • Z: atomic number of the isotope, written as a subscript to the left of the elements's symbol,

        Z = number of protons

The atomic symbol of sodium is Na.

The atomic number, or number of protons, is the same for every isotope of the element, and you can find it in any periodic table. Tha atomic number of sodium is 11. Thus:

  • Z = 11

The mass number is the number of protons plus neutrons, hence:

  • A = 11 + 13 = 24

Now you can write the isotope symbol for the sodium isotope with 13 neutrons:

         ^{24}_{11}Na

How many moles of the product fecl3 do you make, when 8moles of fe react with excess cl2
tatuchka [14]

To figure out questions related to reacting moles/masses, the first step is always to write a complete balanced equation.

2Fe (s) + 3Cl2 (g) → 2FeCl3 (s)

Since Cl2 is the excess reactant, and Fe is the limiting reactant, we can simply find the number of moles of the product by comparing the mole ratio of the limiting reactant to the mole ratio of the product from the equation.

From the equation, mole ratio of Fe:FeCl3 = 2:2 = 1:1, the number of moles of product is exactly the same as the number of moles of the limiting reactant, which makes it 8 moles.

Note that if the mole ratio is not 1:1, you have to do some calculations to make sure the no. of moles is balanced at the end. Which means, if the mole ratio happened to be 1:2, the no. of moles of the product would be 8x2=16 instead.

So, your answer is 8 moles.

The tarnish that forms on objects made of silver is solid silver sulphide. This can be removed by reacting it with aluminium met
steposvetlana [31]

Answer:

5.83 mol.

Explanation:

  • From the balanced reaction:

<em>2Al + 3Ag₂S → 6Ag + Al₂S₃,</em>

It is clear that 2 mol of Al react with 3 mol of Ag₂S to produce 1 mol of Ag and 1 mol of Al₂S₃.

Al reacts with Ag₂S with (2: 3) molar ratio.

<em>So, 2.27 mol of Al reacts completely with 3.4 mol of Ag₂S with (2: 3) molar ratio.</em>

<em />

  • The limiting reactant is Ag₂S.
  • The excess "left over" reactant is Al.

The reamining moles of excess reactant "Al" = 8.1 mol - 2.27 mol = 5.83 mol.
