PH is the concentration of Hydrogen ions (shown as [H+]) in a solution. The scale for pH is 0-14, with 0 being very high acidity and 14 being low acidity (basic). The scale is a logarithmic scale, so this means that each number is 10 times stronger than the number that precedes it.
The pH of the tomato juice is 4, which is more acidic than the black coffee with a pH of 5. Since there is a difference of one number between the two (scale of 1), then this tells us that the concentration of Hydrogen ions in the tomato juice is ten times GREATER than the [H+] of the black coffee.
Δ 1.36 (3H, d, J = 5.5 Hz)
<span>CH*3-CH(X)(Y) </span>
<span>δ 4.63 (1H, q, J = 5.5 Hz) </span>
<span>CH3-CH*(X)(Y) </span>
<span>Note: X anY can't have hydrogen attached, so they are probably O. </span>
<span>δ 3.32 (6H, s); δ 4.63 (1H, q, J = 5.5 Hz) </span>
<span>There is only C2H6O2 remaining, so this must be two CH3 groups; the attachment must be as an ether, and there must be two of them: </span>
<span>CH3-CH(OCH*3)2</span>
As bond number increases (double bonds rather than single, triple rather than double etc. ), bond length decreases and bond energy increases
Reason-Charges that are spaced apart are described by a dipole moment. There are two critical criteria that must be taken into account when assessing if a molecule has a dipole moment. It must first possess polar covalent bonds. The individual dipoles must not cancel out in the molecular structure, which is the second requirement. Because Br2 is not a polar molecule, it lacks a polar covalent bond.A bond number is a simple addition of two numbers that total the sum. Using number bonds, one can quickly determine the answer without performing any calculations. We can see from the example that when we see a number bond, we know the answer without having to calculate.

The Answer would be False.
Answer:
An element is a material that consists of a single type of atom. Each atom type contains the same number of protons. Chemical bonds link elements together to form more complex molecules called compounds. A compound consists of two or more types of elements held together by covalent or ionic bonds.
