Answer:
A single bond, but it's also a hydrogen bond.
Explanation:
A hydrogen bond forms when hydrogen bonds to the 3 most electronegative atoms: Oxygen, Nitrogen, or Fluorine.
It's a single bond because hydrogen only has two valence electrons. Therefore, the rest of the electrons are placed around the nitrogen atom.
Answer:
No
Explanation:
as it would stay sticked on them forerver amd a time of 2 months it will kill them
Fe + NiSO4 ----> FeSO4 + No
NaF + HI ---> NaI + HF
Rock is a combination of two or more minerals, and it does not possess any specific chemical composition. It is present naturally in the environment. Some examples of rocks are limestone, granite, etc.,Limestone may contain minerals like calcite and aragonite. Each mineral has a specific chemical composition with a well defined crystalline structure.
Therefore, the correct option would be a. rock as rock is the naturally occurring solid mass made up of different types of minerals.
Explanation:
Gold conducts heat and electricity. ...
Gold is ductile: It can be drawn out into the thinnest wire. ...
Gold is highly reflective of heat and light. ...
Gold is prized for its beauty. ...
Gold is malleable, so it can be flattened into extremely thin sheets.
on the other hand Gold consist of copper
Key Properties of Copper Alloys
Excellent heat conductivity.
Excellent electrical conductivity.
Good corrosion resistance.
Good biofouling resistance.
Good machinability.
Retention of mechanical and electrical properties at cryogenic temperatures.
Non-magnetic.
so the difference is that copper is less expensive and not priced with its beauty
