Explanation:
Tollens test is carried out to perceive difference between aldehydes and ketones on the basis of their capability to oxidized easily.
when Tollens react with aldehyde (heptanal) , a silver mirror is form on inner side of container.
The reaction between tollens and heptanal is given as
![CH_3 CH_2 CH_2 CH_2 CH_2 CH_2 CHO + 2[Ag(NH_3)_2]+ 3 H_2 O](https://tex.z-dn.net/?f=CH_3%20CH_2%20CH_2%20CH_2%20CH_2%20CH_2%20CHO%20%2B%202%5BAg%28NH_3%29_2%5D%2B%203%20H_2%20O)

Answer:
a beryllium ion because the new atom has 4 protons and 4 neutrons since be has a mass number of 9 then it has to form an ion
Answer:
The Cape Horn was one of the most important routes for maritime trade, leading to sailing vessels.
the difficulty of all this is that it presents great iceberg and climatic factors that do not help the boats. nowadays other commercial routes were created that made this channel only be transited by larger ships, or oil tankers.
Explanation:
Sailing in its waters is still considered one of the greatest nautical challenges, so there are various sporting and tourist events that use this route, some as part of the circumnavigation of the globe, among which are important yacht regattas, such as the Vendée Globe.
16 g/ml
<h3>Further explanation</h3>
Given
mass = 32.40 g
volume = 2.0mL
Required
Density
Solution
Density is a quantity derived from the mass and volume
Density is the ratio of mass per unit volume
Density formula:
ρ = density
m = mass
v = volume
Input the value :
ρ = 32.40 g / 2.0 ml
ρ = 16.2 g/ml
Rules for division: The least number of significant figures in the problem determines the number of significant figures in the answer.
32.40 = 4 sig.fig
2.0 = 2 sig fig
The answer must be 2 sig fig
So the answer = 16 g/ml
