Answer:
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
Explanation:
Explanation:
When there is transfer of electrons between two atoms then it results in the formation of an ionic bond.
Whereas when there is sharing of electrons between two atoms then it results in the formation of covalent bond.
, , and are ionic compounds as there is bond formation between a metal and a non-metal. So, there will be transfer of electrons and as a result, ionic bond is formed.
is a compound which contains non-metals C and S. Therefore, bond formation is due to sharing of electrons thus, there is covalent bond.
has symmetrical structure and will have equal sharing of electrons. Hence, the molecule will have non-polar covalent bond.
Answer: capillary action
Explanation: it occurs when the adhesion forces (attraction between two surfaces or substances) in the liquid are stronger than the cohesion forces (attraction between the same molecule)
Instrumental methods of analysis rely on machines.The visualization of single molecules, single biological cells, biological tissues and nanomaterials is very important and attractive approach in analytical science.
There are several different types of instrumental analysis. Some are suitable for detecting and identifying elements, while others are better suited to compounds. In general, instrumental methods of analysis are:
-Fast
-Accurate (they reliably identify elements and compounds)
-Sensitive (they can detect very small amounts of a substance in a small amount of sample)
Answer:
<em>»</em><em> </em><em>λ </em><em>=</em><em> </em><em>0</em><em>.</em><em>0</em><em>2</em><em>m</em>
Explanation:
Given :
Velocity of the wave {v}= 12 m/s
Frequency {f} = 600 Hz
Apply Wavelength formula :
•
→ λ =
→ λ =
→ λ = 0.02m
