Explanation:
Making a list of chemical and physical properties of different substances, will makes the study of these substances easier. The physical properties like mass density volume of a substance helps in measuring and knowing the amount of substance taken for a certain use.
While Enlisting the chemical properties of certain substances we see which two substances can be mixed or are allowed to react to get some required substance just by looking at the list without performing a sample reaction to check every time.
Answer: The correct answer is Aldose.
-
A disaccharide is produced when two monosaccharides are linked by a glycosidic bond.
- Any carbohydrate which has six carbon atoms is called as hexose. It is a monosaccharide. The functional group in hexose can be aldehyde or ketone.
- Ketose is a carbohydrate which contains ketone as a functional group.
Aldose, as the name suggests, it means having aldehyde group. Thus, it is a carbohydrate which has aldehyde as a functional group.
Example- D- Glyceraldehyde.
Use afbau rules to fill in electrons for the Ununoctium(118) element. This is called electron configuration, so you ll have to fallow 3 rules:
- first electrons with same spin.
- first pair the eletrons in the same orbital (every level/row of dots)
- 3d > 4s... there is crossings you will notice, meaning 3d is an orbital level with higher energy in compare to 4s. So it is written 4s3d4p insetead of 3d4s4p ...
You complete it by adding electrons following example:
2p3 woud be: (|)(|)(|), and
2p6 would be: (||)(||)(||)
So in this questionfor Uuo you just have to fill every dot with two straight lines representing electrons...
Answer:
a) Pb(NO3)2 + 2KI ⇒ PbI2 + 2K(NO3)
ion that form the precipitate = Pb2+ and I-
Spectator ions = NO3. and K+
b) Pb 2+ + 2 I- ⇒ PbI2
Explanation:
Answer:
see below
Explanation:
the charge of the atom is neutral because there are equal numbers of protons and electrons in an atom.
