Concept explainers
(a)
Interpretation:
The electron dot structure for the compound C2H2O is to be drawn.
Concept introduction:
The electron dot structure of any compound is the structure in which each element is properly represented with the help of symbols and lone pairs present on the elements are shown with the help of a pair of dots above that element.
(b)
Interpretation:
The orbital overlap picture of ethenone is to be drawn.
Concept introduction:
In chemistry, overlapping of orbital takes place to form bonds between the atoms. At least two orbitals must overlap with each other to form a bond. The examples of orbitals are s, p, d, f orbitals.Sigma bond involves the head to head overlapping of two orbitals; on the other hand, pi bond involves the side to side or lateral overlapping of two orbitals.
The lone pairs are unpaired electron present in the orbitals of the atom. Oxygen has two pairs of lone pair.

- Use the provided information to calculate Kc for the following reaction at 550 °C: H2(g) + CO2(g) ⇌ CO(g) + H2O(g) Kc = ?CoO(s) + CO(g) ⇌ Co(s) + CO2(g) Kc1 = 490CoO(s) + H2(g) ⇌ Co(s) + H2O(g) Kc2 = 67arrow_forwardCalculate Kc for the reaction: I2 (g) ⇋ 2 I (g) Kp = 6.26 x 10-22 at 298Karrow_forwardFor each scenario below, select the color of the solution using the indicator thymol blue during the titration. When you first add indicator to your Na2CO3solution, the solution is basic (pH ~10), and the color is ["", "", "", "", ""] . At the equivalence point for the titration, the moles of added HCl are equal to the moles of Na2CO3. One drop (or less!) past this is called the endpoint. The added HCl begins to titrate the thymol blue indicator itself. At the endpoint, the indicator color is ["", "", "", "", ""] . When you weren't paying attention and added too much HCl (~12 mL extra), the color is ["", "", "", "", ""] . When you really weren't paying attention and reached the second equivalence point of Na2CO3, the color isarrow_forward
