Answer:
Wavelength (typically measured in nanometers) is the distance between two points in a wave.Frequency (typically measured in Hertz) is the number of waves in a specific time . Frequency and wavelength have both direct and inverse relationships. The crucial difference between frequency and wavelength is that frequency shows the total number of wave oscillations in a given time. As against wavelength specifies the distance between two specific points of a wave.
Explanation:
Frequency is how often something changes per second be it amplitude of a voltage on a wire or be it the bobbing back and forth of a bobblehead. Frequency is how often something moves up and down in a second. If a bobble head moves forward and backward in one second then it has a bobbling frequency of 1 Hertz (Hz). The unit of frequency is Hertz (Hz) or # of cycles or oscillations per second. A wavelength is measured in distance like meters (m). For photons or light or radiowaves the equation is wavelength=speed of light/frequency.
<span>Ammonium ion when protonated, the result ammonium ion is not electophilic where in the case of iminium ion when protonated the result is electrophilic iminium ion that would have tendency to attract electrons. Protonate means sending a proton to the molecule to form a coordinate bond.</span>
Answer:
amine
Explanation:
We have to bear in mind that amines are basic compounds. This idea will be very important in attempting to answer this question.
So, when she adds 5% HCl solution in order to extract the organic layer, the amine forms a hydrochloride salt which is contained in the aqueous layer.
The addition of a base such as NaOH leads to the formation of a white precipitate of the amine.
Answer:
Explanation:
Formula of percent composition:
% X = ( mass of element in compound / total mass of compound ) × 100
11) Al₂O₃
Al = 27 g/mol
O = 16 g/mol
%Al = (54 / 101.96) × 100
%Al = 52.9%
%O = (48 / 101.96) × 100
%O = 47.1%
12) C₅H₅O₅
C = 12 g/mol
H = 1 g/mol
O = 16 g/mol
C% = (60 / 145 ) × 100
C% =41.4%
H% = (5 / 145 ) × 100
H% =3.4%
O% = (80 / 145 ) × 100
O% = 55.2%
13) BaBr₂
Ba = 137.3 g/mol
Br =79.9 g/mol
Ba% = (137.3 / 297.14) × 100
Ba% = 46.2%
Br% = (159.8/ 297.14) × 100
Br% = 53.8%
14) Fe₃(PO₃)₂
Fe = 55.8 g/mol
P = 31 g/mol
O = 16 g/mol
Fe = (167.4/325.48) × 100
Fe = 51.43%
P = (62/325.48) × 100
P = 19.05%
O = (96 /325.48) × 100
O = 29.49%
