For a polar molecule<span>, your bonds will not cancel out. This means that in a </span>polar<span> bond, the electronegativity of the atoms will be different. For </span>nonpolar<span> bonds the electronegativity of the atoms will be equal. In a </span>polar<span> bond you will have an unequal sharing of electron pairs which causes a molecular dipole.</span>
The activation energy in the
diagram is 43.8 kcal/ mole, letter C. You have to note that activation energy
is the energy needed for the reaction to occur and produce products. Therefore,
the spike after H2 and I2 is reacted is the activation energy of the reaction.
It cracks the land on the earth and makes an erosion for the building like leaving cracks on the walls or the floor or both, and maybe the building falling
Answer:
1.the highest point of the wave is the crest while lowest point is trough.
2.?
3. wave length
4. frequency
5. A is crest b is trough c is amplitude and d is wave length
7.a = this is longitudinal wave, b no = letter h represents a compression and letter I represents rarefactions , letter g represents a wave length.
8 . in transverse wave
9. longitudinal wave
10. longitudinal wave
11. transverse wave
12. ?
