The answer is covalent bonding. Molecular compounds are made of 2 or more nonmetals, and are therefore covalent. That is why another name for "molecular compound" is "covalent compound".
Answer: (1) covalent bonding
Hope this helped!! :D
It is called DISPLACEMENT of the object....
Answer:
D) Low temperatures
Explanation:
Non-metals are elements that do not show metallic characteristics like heat conductivity, electrical conductivity, malleability, e.t.c. They are generally less dense and are bonded with weak forces in between their compounds.
The weakness of non-metals is the chief reason why they generally tend to have low boiling point. Only the presence of impurities can cause an elevation in their boiling points.
Metals on the other hand are good heat conductors and they generally have a high boiling point.
Answer:No of moles of potassium sulfide (K2S)=0.61671moles
Explanation:
No of moles is given as Mass/ molar mass
Here Mass of potassium sulfide (K2S) =68 grams
Molar mass of potassium sulfide (K2S) = 39.0983 x 2 + 32.065 =110.2616 g/mol
No of moles =68 grams /110.2616 g/mol
=0.61671moles
