Answer:
cis-3,4-dimethyl-3-hexene
Explanation: since the substituents are on same side, it call cis. Followed by the name
D. It is a chemical change because solubility in water of Solid A is different than the solubility in water or both Potassium Iodide and Silver Nitrate
Explanation:
From the given table which summarizes findings about the experiment, we can conclude that It is a chemical change because solubility in water of Solid A is different than the solubility in water of both Potassium Iodide and Silver Nitrate.
- A chemical change is a form of change in which new substances are produced.
- A physical change is one in which the states of matter changes especially the form.
Now we that two soluble substances goes to insoluble product.
- A substance is soluble when they go into solution with a solvent of the same type.
- This change from solubility to insolubility of a compound is a typical chemical change.
- Other forms of changes are just physical changes.

Answer:
Percentage yield is 96.15%
Explanation:
Theoretical yield = 13.0g
Actual yield = 12.5g
Percentage yield = ?
Equation of reaction
2Na + Cl₂ → 2NaCl
Percentage yield = (actual yield / theoretical yield) * 100
Percentage yield = (12.5 / 13.0) * 100
Percentage yield = 0.9615 * 100
Percentage yield = 96.15%
Percentage yield of NaCl is 96.15%
