In case you're in hurry:
Ans: 26 valence electrons

Explanation:
To find the valence electrons, we need to add the valence electrons of the individual atom in the compound. Therefore, let us divide this question into 3 parts.

1) What is the number of valence electrons of Arsenic (As)?
2) What is the number of valence electrons of Oxygen (O)?
3) What is the total number of valence electrons of AsO_{3}^{3-}

1.
The number of valence electrons of Arsenic(As) = 5

2.
The number of valence electrons of Oxygen (O) = 6

3.

Since there are 3 atoms of Oxygen, and 3 extra electrons are also present in the shape of "3-", as it is an ion, therefore,

The total number of valence electrons of AsO_{3}^{3-} = 5 + 6 * 3 + 3 = 26 valence electrons.

Ans: The total number of valence electrons in 
AsO_{3}^{3-} = 26.

Aleks [24]

Answer:

K_{p}=4.35\times 10^{-4}

Explanation:

We know, K_{p}=K_{c}(RT)^{\Delta n}

where, R = 0.0821 L.atm/(mol.K), T is temperature in kelvin and \Delta n is difference in sum of stoichiometric coefficient of products and reactants

Here \Delta n=(2)-(2+1)=-1 and T = 311 K

So, K_{p}=(0.0111)\times [(0.0821L.atm.mol^{-1}.K^{-1})\times 311K]^{-1}=4.35\times 10^{-4}

Hence value of equilibrium constant in terms of partial pressure (K_{p}) is 4.35\times 10^{-4}

Answer:

0.07172 L = 7.172 mL.

Explanation:

  • We can use the general law of ideal gas: <em>PV = nRT. </em>

where, P is the pressure of the gas in atm (P = 1.0 atm, Standard P).

V is the volume of the gas in L (V = ??? L).

n is the no. of moles of the gas in mol (n = 3.2 x 10⁻³ mol).

R is the general gas constant (R = 0.0821 L.atm/mol.K),

T is the temperature of the gas in K (T = 273 K, Standard T).

<em>∴ V = nRT/P =</em> (3.2 x 10⁻³ mol)(0.0821 L.atm/mol.K)(273 K)/(1.0 atm) = <em>0.07172 L = 7.172 mL.</em>

tekilochka [14]
Covalent bonds = sharing of electrons between two atoms of the same elements or elements close to each other on the periodic table. Usually they are metals sometimes non-metals. In polar bonds electrons are shared unequally. Non polar bonds share electrons equally.
