Okay so, 24.00 mL of a 0.25 M NaOH solution is titrated.
Hey there!
Electrons are negatively charged and orbit the nucleus of the atom on energy levels (kind of in a cloud) :)

Answer : The correct option is, forms of the same element that differ in the number of neutrons in each atom
Explanation :
Isotopes : It is defined as the forms of same element that have the same number of protons and electrons but differ in the number of neutrons.
For example : Carbon-12, carbon-13 and carbon-14 is an isotopes due to the same number of protons and electrons and different number of neutrons.
Carbon-12
Atomic number = 6
Atomic mass = 12
Atomic number = Number of protons = Number of electrons = 6
Number of neutrons = Atomic mass - Atomic number = 12 - 6 = 6
Carbon-13
Atomic number = 6
Atomic mass = 13
Atomic number = Number of protons = Number of electrons = 6
Number of neutrons = Atomic mass - Atomic number = 13 - 6 = 7
Carbon-14
Atomic number = 6
Atomic mass = 14
Atomic number = Number of protons = Number of electrons = 6
Number of neutrons = Atomic mass - Atomic number = 14 - 6 = 8
The hydrogenation of ethyl cinnamate will result to an ester which can be a racemic mixture of products or just a meso compound depending on the structure of the ethyl cinnamate (cis or trans). The ester will produce a frequency of C=O stretch of <span>1750 - 1735 (s.</span>
