Answer:
ch3c(ch3)(oh)ch3
Explanation:
that should be the answer
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.
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>
Three things that should happen for a chemical reaction to occure :
1. Position of electrons must change
2. Chemical bonds must be formed and broken between atoms and
3. No changes should happen to the nuclei
