<span>Answer:
Anthracene is a solid polycyclic aromatic hydrocarbon (PAH) which has the formula as C14H10, consisting of three fused benzene rings. It is a component of coal tar. Anthracene is used in the production of the red dye alizarin and other dyes.</span>
Answer:
it's C. but the sentence is incorrect I think it should be a ball "in" someone's hand
Explanation:
cause potential energy is the energy that is stored in an object due to its position relative to some zero position. An object possesses gravitational potential energy if it is positioned at a height above (or below) the zero height.
If you know PV=nRT formula it should be clear that the pressure <span>inversely proportional to the volume. Density is directly proportional to volume, so it also inversely proportional to the pressure (assuming the same mass of substance used).
The calculation for this question would be: 760mm*13.6 / 1.26= 8203.17 mm * 1000 meter/mm= 8.2 meter</span>
Explanation:
wavelength=speed of light/frequency
=(3×10^8)/2.99
=1.0033 × 10^8
Answer:
Polymerization
Explanation:
Several natural and man-made organic compounds are enormous molecules which contains hundreds of thousands of atoms per molecule.
The giant molecules formed are produced through the process of polymerization.
Polymerization is the linking of monomers through chemical reactions to form long chain polymer molecules.
Monomers are small molecules that are joined to form polymers.
Synthetic plastics are derieved from synthetic polymers. These synthetic materials are very useful and vital due to their great size. Their size premits a certain complexity of structure which makes the molecules disposed in a regular pattern with respect to one another. They stretch out nearly to alongside of one another or coil up independently. The polymerization of monomers to form plastics fosters the various uses these giant molecules are put to.
