Answer: The Answer is A.
Explanation:
The amount of energy is directly proportional to the photon's electromagnetic frequency and thus, equivalently, is inversely proportional to the wavelength. The higher the photon's frequency, the higher its energy. Equivalently, the longer the photon's wavelength, the lower its energy.

Answer:
amino group
Explanation:
There are twenty (20) amino acids in nature. Generally, each amino acid is structurally made up of a central carbon atom called alpha carbon attached to a hydrogen, carboxylic acid group (-COOH) and an amine group (-NH2). However, one particular amino acid called PROLINE posseses an exception to this.
Proline, which is the only cyclic amino acid, is also the only amino acid that forms a secondary amine group i.e. loss of hydrogen atoms in its amine group when in a protein structure. This means that when in a protein, PROLINE does not have an AMINE GROUP.

Math expression: 
Explanation:
<u>Given:</u>
Energy produced per gram of gasoline = 45.0 kJ
Density of gasoline = 0.77 g/ml
Volume of gasoline = 5.2 L=5200 ml
<u>To determine:</u>
The amount of energy produced by burning 5.2 L gasoline
<u>Calculation set-up:</u>
1. Calculate the mass (m) of gasoline given the density (d) and volume (v)
2. Calculate the amount of energy produced
Answer:
25.39
Explanation:
Given parameters:
Abundance of X-25 = 80.5%
Abundance of X - 27 = 19.5%
Unknown:
Average atomic mass of X = ?
Solution:
The average atomic mass of X can be derived using the expression below:
Average atomic mass = (abundance x mass of X - 25) + (abundance x mass of X - 27)
Average atomic mass = (80.5% x 25) + (19.5% x 27) = 25.39
2AgNO3+K2CrO4⇒Ag2CrO4(s)+2KNO3
Hence by mixing 0.0024M AgNO3 and 0.004M
K2CrO4, we will have Ag2CrO4 which is precipitated out and leave us with
0.0024M KN03 which is mixed with (0.004-0.0024/2)M, it can be 0.0028M, of K2Cr04
