Hope that helped :)
What are the following options?
Answer:
See explanation
Explanation:
We know that in the presence of strong oxidizing agents such as permanganate , aldehydes are oxidized. This oxidation is often accompanied by a colour change.
The colour change in the permanganate oxidation of benzaldehyde is caused by the inorganic permangate. The colour changes from purple to colourless because Mn^7+ is reduced to Mn^2+.
The benzaldehyde is readily oxidized to benzoic acid in the presence of permanganate.
Answer:
(1) The two column proof is presented here as follows;
Statement 
Reasons
1. C is the midpoint of 
Given
B is the midpoint of 
D is the midpoint of 
2. AC = CE, AB = BC, CD = DE Definition of midpoint
3. AB + BC = AC, CD + DE = CE Segment addition postulate
4. CD + DE = AC Substitution property of equality
5. AB + BC = CD + DE Substitution property of equality
6. BC + BC = CD + CD Substitution property of equality
7. 2·BC = 2·CD Addition of two identical quantities
8. BC = CD Division property of equality
9. BC ≅ CD Definition of Congruence
(2) The two column proof for the triangular geometric figure is presented here as follows;
Statement Reasons
1. 2·WV = XY; 2·YZ = XW; WV = YZ Given
2. 2·WV = 2·YZ Multiplication property
3. XY = XW Substitution Property
4. XW + WV = XV Segment Addition Property
XY + YZ = XZ
5. XW + WV = XV Substitution Property
XW + WV = XZ
6. XV = XZ Substitution Property
