A non polar covalent bond because the electronegativity of the two atoms are not so different. Therefore the electron dwells equal for both atoms.

Answer: Option (c) is the correct answer.

Explanation:

A non-polar covalent bond is defined as the bond formed due to equal sharing of electrons between the combining atoms.

For example, in a Cl_{2} molecule there will be sharing of only one electron by each chlorine atom. This is because here electronegativity difference is zero so, there will be no attraction of electrons by either of the chlorine atoms.

Hence, no charges will tend to develop.

A polar covalent bond is formed when there occurs unequal sharing of electrons between the two combining atoms.

For example, in HCl the chlorine is more electronegative in nature. Hence, it will attract the electron from hydrogen atom more towards itself. As a result, partial charges will develop.

An ionic bond is defined as the bond formed due to sharing of electrons between a metal and a non-metal.

For example, KCl is an ionic compound.

Thus, we can conclude that the type of bond produced when atoms share electrons equally is a non-polar covalent bond.

What is the ph of pure water at 40.0°c if the kw at this temperature is 2.92 × 10-14?
olganol [36]

Answer: pH = 6.77

Explanation:

1) <u>Chemical equilibrium</u>

  • 2 H₂O (l) ⇄ H₃O⁺ (aq) + OH⁻ (aq)

2) <u>Equilibrium constant, Kw</u>

  • Kw = [H₃O⁺] × [OH⁻]
  • By stoichiometry [H₃O⁺] = [OH⁻]. Call it x
  • Kw = x²
  • x² = 2.92 × 10⁻¹⁴ M²
  • x = √ (2.92 × 10⁻¹⁴) = 1.709 × 10⁻⁷ M = [H₃O⁺]

3)<u> pH</u>

  • pH = - log [H₃O⁺] = - log (1.709 × 10⁻⁷) = 6.77

2. Calculate how many moles of H2 would be produced if 0.250 mol of Fe reacts completely. (1 mark)
den301095 [7]

Hey there!:

Balanced Equation , for the reaction:

3 H₂SO₄(aq) + 2 Fe(s) → Fe₂(SO₄)₃(aq) + 3 H₂(g)

2 moles Fe ---------------------------------- 3 moles H₂

0.250 moles Fe ---------------------------- ( moles H₂ ) ??

____________________________________________

moles H₂ = 0.250 × 3 / 2

moles H₂ = 0.75 / 2

moles = 0.375 moles of H₂

Hope this helps!

Can waves travel through empty space? why?
jok3333 [9.3K]

Answer:

Elctromagnetic waves can travel through empty space.

Explanation:

Waves that may pass through matter or empty space are known as electromagnetic waves. The electromagnetic field, like the other basic fields, penetrates the whole universe, including the region we refer to as empty space. There are no fields in space. The medium through which electromagnetic waves travel is called the electromagnetic field.

A different atom of iodine has a mass number of 128. What is this atoms relationship to the atom with a mass of 126
Mkey [24]

Answer:

The answer is below

Explanation:

They are isotopes. Isotopes are molecules that have the same atomic number but have different atomic mass because the number of neutrons is different.

Iodine has an atomic mass of 126 g and its atomic number is 53.

# of neutrons = 126 - 53 = 73

Its isotope has an atomic mass of 128 g its atomic number is also 53, but the number of neutrons is different.

# neutrons = 128 -53 = 75
