5. Which statement is true about electronegativity?
Anit [1.1K]

Answer:

Electronegativity generally increases from left to right across a period,

Explanation:

The true statement from the given choices is that electronegativity generally increases from left to right across a period.

Electronegativity is the measure of the relative tendency with which an atom of the element attract valence electrons in a chemical bond.

Across a period electronegativity increases from left to right and decreases down the group.

This is due to reduction in metallic properties as we move across the period from left to right.

Sulfur trioxide is a gas that reacts with liquid water to produce aqueous sulfuric Acid or acid rain what is the equation for th
bearhunter [10]

Answer:

SO₃(g) + H₂O(l) → H₂SO₄(aq)

Explanation:

The<em> molecular formula for the involved species</em> are:

  • Sulfur trioxide = SO₃. ("trioxide" indicates the presence of 3 oxygen atoms).
  • Water = H₂O
  • Sulfuric acid = H₂SO₄

With the above information in mind we can proceed to write the reaction equation:

  • SO₃(g) + H₂O(l) → H₂SO₄(aq)
