Answer:
1) C
2)A
3)D
Explanation:
London forces are common to all molecules, it results from momentary shifts in electron distribution in molecules. When molecules possess a permanent dipole, dipole-dipole interaction is the dominant intermolecular force. However, for compounds in which hydrogen is bonded to highly electronegative element, hydrogen bonding is important.
Answer:
because there more acid in diet cola
The answer is not D, because water creates turgidity.
The answer is not C, because water is important in many biological reactions.
The answer is either A, or B. Knowing that water composes almost 75% of the body, you can assume that It is a common substance, for A, or you could know that is allows reactions to occur more easily, acting as a sort of catalyst, for answer B.
A or B. Your call for the final answer.
Answer:
3.077 × 10¹⁴ Hz
Explanation:
f = ?
wavelength = 9.75 × 10-⁷m
using the formula,
c = wavelength × frequency
f = c/wavelength
but c(speed of light) = 3×10⁸m/s
f = 3 × 10⁸/9.75 × 10-⁷
f = 3.077 × 10¹⁴ s-¹
