Answer:

A) C₅H₁₂O(l) + 7.5 O₂(g) → 5 CO₂(g) + 6 H₂O(l)

B) No reaction

C) SrS(aq) + CuSO₄(aq) → CuS(s)↓ + SrSO₄(aq)

Explanation:

<em>A) liquid pentanol (C₅H₁₂O) and gaseous oxygen.</em>

This is a combustion reaction. assuming the combustion is complete, the products are CO₂ and H₂O.

C₅H₁₂O(l) + 7.5 O₂(g) → 5 CO₂(g) + 6 H₂O(l)

<em>B) aqueous ammonium chloride and aqueous calcium hydroxide.</em>

We could expect a double displacement reaction to take place. But since the products are CaCl₂ and NH₄OH, both of them soluble, no reaction occurs.

<em>C)aqueous strontium sulfide and aqueous copper(II) sulfate.</em>

This is a double displacement reaction. The formed precipitate is CuS.

SrS(aq) + CuSO₄(aq) → CuS(s)↓ + SrSO₄(aq)

If oxygen with an electronegativity of 3.5 were to make a chemical bond with lithium, electronegativity of 1.0, what kind of bon
sergejj [24]

Answer:

Ionic.

Explanation:

Elements with higher electronegativity values are better at attracting electrons in a chemical bond.  

  • A chemical bond is considered "ionic" if the electronegativity difference between the two bonding atoms is greater than 1.8.
  • Otherwise, this chemical bond is considered "covalent".

In this example, the difference between the electronegativity of oxygen and lithium is 3.5 - 1.0 = 2.5. Since 2.5 > 1.8, the bond between the two elements would likely be ionic.

It is possible to reach the same conclusion based on the fact that lithium is a metal while oxygen is a nonmetal. When metal elements react with non-metal elements, the product is typically an ionic compound- with ionic bonds between the atoms.
