Which of these statements would be true if the water molecule was linear instead of bent? Check all that apply.
Katen [24]

If the water molecule was linear instead of bent the water would no longer produce hydrogen bonds.

<u>Explanation:</u>

  • Yes, If the water molecule was linear instead of bent the water would no longer produce hydrogen bonds.
  • The water would no longer generate hydrogen bonds.
  • It will lose its polar features and nearly all of its features will change such as boiling point, water tension and solubility.
  • It would be more like to gas, rather than liquid.
  • If the water was in the linear, the water would have all the features and it would produce  the hydrogen bonds.

Please Help! Use Hess’s Law to determine the ΔHrxn for: Ca (s) + ½ O2 (g) → CaO (s) Given: Ca (s) + 2 H+ (aq) → Ca2+ (aq) + H2 (
poizon [28]

Answer:

ΔHrxn = -635.14kJ/mol

Explanation:

We can make algebraic operations of reactions until obtain the desire reaction and, ΔH of the reaction must be operated in the same way to obtain the ΔH of the desire reaction (Hess's law). Using the reactions:

(1)Ca(s) + 2 H+(aq) → Ca2+(aq) + H2(g) ΔH = 1925.9 kJ/mol

(2) 2H2(g) + O2 g) → 2 H2O(l) ΔH = −571.68 kJ/mole

(3) CaO(s) + 2 H+(aq) → Ca2+(aq) + H2O(l) ΔH = 2275.2 kJ/mole

Reaction (1) - (3) produce:

Ca(s) + H2O(l) → H2(g) + CaO(s)

ΔH = 1925.9kJ/mol - 2275.2kJ/mol = -349.3kJ/mol

Now this reaction + 1/2(2):

Ca(s) + ½ O2(g) → CaO(s)

ΔH = -349.3kJ/mol + 1/2 (-571.68kJ/mol)

<h3>ΔHrxn = -635.14kJ/mol</h3>
