DIPOLES FORM AT EACH BOND BETWEEN HYDROGEN AND OXYGEN IN A WATER MOLECULE BECAUSE _

Chemistry

Answer:

Dipole form on each bond between hydrogen and oxygen atom in water molecule because of the electronegativity difference

between hydrogen and oxygen.

Explanation : Electronegativity means attraction of shared pair of electron toward itself in the covalent bond. Those atoms having same electronegativity values, the shared electron remain in the center whereas those atoms having different electronegativity values, the shared pair of electron is attracted by the atom having high value of electronegativity. In water molecule, electronegativity of oxygen is higher so it attracts electron pair towards itself and forms negative pole and hydrogen aquire positive pole.

What is the concentration of hydronium ion in a 0.121 M HCl solution?

kogti [31]

Answer:

C) 0.121 M

Explanation:

HCl + H₂O = H₃O⁺ + OH⁻

.121M .121M

HCl is a strong acid . It will dissociate almost 100 % so the concentration of acid and hydronium ion formed will be equal . It is to be noted that hydronium ion is formed due to association of H⁺ and H₂O . H⁺ is formed due to ionisation of HCl .

So concentrtion of hydronium ion ( H₃O⁺ ) will be .121 M.

Dinitrogen pentoxide is used in the preparation of explosives. If 7.93 mol of

Tpy6a [65]

The volume of O₂ produced: 84.6 L

<h3>Further explanation</h3>

Given

7.93 mol of dinitrogen pentoxide

T = 48 + 273 = 321 K

P = 125 kPa = 1,23365 atm

Required

Volume of O₂

Solution

Decomposition reaction of dinitrogen pentoxide

2N₂O₅(g)→4NO₂(g)+O₂ (g)

From the equation, mol ratio N₂O₅ : O₂ = 2 : 1, so mol O₂ :

= 0.5 x mol N₂O₅

= 0.5 x 7.93

= 3.965 moles

The volume of O₂ :

$\tt V=\dfrac{nRT}{P}\\\\V=\dfrac{3.965\times 0.082\times 321}{1.23365}\\\\V=84.6~L$
