Answer:
polymerization
Explanation:
Student is explaining the process of formation of a polymer and the process is called polymerization.
Polymer is made up of joining repeating units. The repeating units are called monomers.
Properties of the polymer is determined by the structure of monomer molecule.
For example, consider a well-known polymer Teflon.is made by the polymerization of tetrafluoroethane.
Thus, the student is explaining polymerization.
I believe the answer is D being all of the above
Answer:
infrared waves are longer than gamma rays
Explanation:
according to the order :
radio, microwaves, infrared, light, ultraviolet, X-ray, gamma rays
radio waves have the highest wavelenght and lowest frequency, gamma rays have the highest frequency and lowest wavelength.
Answer:
Concentration of A at equilibrium = 1 - 0.5 = 0.5 M
Explanation:
Equilibrium constant = 0.5
Initial concentration of A = 1 M
Initial 1 0 0
At equi. 1-x x x
Equilibrium constant =
on solving,
x = 0.5 M
Concentration of A at equilibrium = 1 - 0.5 = 0.5 M
Answer:
See explanation below
Explanation:
What we have to consider is the hybridation of the three carbon atoms we are asked in this question .
Hybridization # bonds Angle
sp³ 4 109.5º
sp² 3 + 1 pi bond 120º
sp 2 + 2 pi bonds 180º
Carbon atom (a) is bonded to two atoms: Carbon (b) and one Hydrogen. It has a triple bond to Carbon (b). Therefore its hybridization is sp with two pi bonds, and for sp hybridization we know the angle is 180 º.
The same hybridization sp happens to carbon (b) bonded to Carbon (c) and C(a) using one sp bond to Carbon (a) and 2 pi bonds; it is also bonded using the other sp to Carbon (c). The angle is therefore 180 between Carbons b and c.
Carbon C is bonded to 4 atoms, therefore, its hybridization is sp³ and the angles with these 4 atoms will be 109.5 º tehedral ( one bond to OH, one to C(b), and 2 to H ) .
