Nanochemicals can be defined as chemicals generated by using nanomaterials (materials that possess of size on nanometer dimensions). The nanochemicals are used in multiple different applications including chemical warfare, bicycle making, armor design and military weapons crafting. The most commonly used and observed nanochemicals are carbon nanotubes that are used a ton in industry for applications such as stronger materials (stronger bicycles).
Smart materials are exquisitely designed materials whose property(ies) can be modified with the use of an external stimulus such as temperature, stress, pH, and so on. Some examples of smart materials include shape memory materials, piezoelectric materials, ferrofluids, self-healing materials, and such. Applications involve memory pillows, memory based solar panels (for satellites), light sensitive glasses, and so on.
Specialized materials are made specifically to perform a specified task or function. Applications involve electronic equipment (high purity silicon & germanium), machine tools (high tungsten high carbon steel), dental filling (dental amalgam), and so on.
Answer:
Option (A)
Explanation:
The correlation of rocks is usually defined as a technique that helps in determining the age of the rocks that are mostly characterized by the presence of similar fossil/fossil assemblages. These fossils that are used are mainly the index fossils that appeared for a short geological time and were very widely distributed on earth's surface. By determining the age of these fossils, the rocks in which these fossils are found were concluded to be formed during the same age.
This method is efficient to use for the geologists where the fossils acts as a tool to determine the age of the rocks. For the correlation of rocks, scientists look for a similar type of fossils that are found in different places.
Thus, the correct answer is option (A).
V=0.650 L
c=0.505 mol/L
M(Na₂CO₃)=106.0 g/mol
the amount of substance of sodium carbonate is:
n(Na₂CO₃)=vc
the mass of sodium carbonate is:
m(Na₂CO₃)=n(Na₂CO₃)M(Na₂CO₃)
m(Na₂CO₃)=vcM(Na₂CO₃)
m(Na₂CO₃)=0.650*0.505*106.0=34.7945 g
Development of cancer drugs seems to be the only answer related to chemistry so i’d say go with that one
