1-H NMR spectroscopy tool will be used for distinguishing a sample of 1,2,2-tribromopropane from 1,1,2-tribromopropane.

The preferred method for determining or validating the structure of organic molecules or those containing protons is H NMR. When compared to other nuclei, a solution-state proton spectrum may be obtained relatively quickly, and it contains a wealth of knowledge regarding a compound's structure.

It can be calculated by simply counting the number of unique hydrogens on one side of the symmetry plane will give you the count of signals individual molecules emit in a 1H NMR spectrum.

Therefore, 1-H NMR spectroscopy tool will be used for distinguishing a sample of 1,2,2-tribromopropane from 1,1,2-tribromopropane.

1. Which two particles are found in the nucleus of an atom?
Nataly_w [17]
The answers are as follows:
1. C
An atom is made up of three particles, which are electron, proton and neutron.
The proton and the neutron are located in the central part of the atom, which is called the nucleus while the electrons orbit around the nucleus. The electron is negatively charged, the proton is positively charged and the neutron does not have any charge.

2. C.
To calculate the average atomic mass of the element, divide the percentage abundance by 100 and then multiply the mass and the abundance value together for each element. After this add all the values obtained together.
a. Mass * abundance = 23.9850 * 0.7899 = 18.9457515
b. Mass * abundance = 24.9858 * 0.1 = 2.49858
c. Mass * abundance = 25.9826 * 0.1101 = 2.86068426
Relative atomic mass = 18.9457515 + 2.49858 + 2.86068426 = 24.30.

3. A particle that orbit the nucleus is called AN ELECTRON.
An electron is the negatively charged component of the atom, which orbit round the nucleus of an atom. The number of electrons that are orbiting round the nucleus of a particular atom depends on the atomic number of that atom.
4. C.
If an element has a charge of -1, that means that the element has gained one electron in the course of chemical bonding and has become an anion. Normally, for a neutral element, the number of proton, neutron and electron ought to be the same. But in the situation where an element has gained one electron, the number of electron will increase by 1 while the number of proton and neutron remain the same. That is why 9, 9, 10 written at option C is correct.

5. D.
An isotope is defined as an element, which has two or more forms which differ in the number of neutrons in their nucleus. An isotope is an element which exist in several forms. The major difference between isotopes is the number of neutrons in their nucleus and this neutron number eventually determine their relative atomic mass. Thus two isotopes will have different neutron number and different mass number.

6. B.
In the diagram given, there are five neutrons, four proton and two electrons. The atomic particles that can be used here to determine the correct element are neutrons and protons, this is because they do not participate in chemical bonding therefore there number is always constant. The proton number of four indicates that the element we are searching for is beryllium, because beryllium has four protons and five neutrons in its nucleus.

7. B.
The atomic number of iron is 26 but its mass number is 56. Since its atoms are composed of three different particles, the particles number are as follows: electron = 26, proton = 26 and neutron = 30.
Neutron number = mass number - proton number = 56 - 26 = 30.
 In the question we are given, the iron element has undergone a bonding process and it has given away two electrons, to become a cation, that is why it is written as Fe2+. Thus, its electron number will become: 26 - 2 = 24. But this process does not affect the neutron number.

8. D.
Quarks refer to subatomic particles which possess fractional electric charges. They are usually find in the proton and the neutron which are located inside the nucleus of an atom. Quark is not found in electrons.

9. D.
The atomic number of sulfur is 16, that means that, it has 16 electrons, 16 protons and 16 neutrons in its atom at the neutral state. Sulfur has many isotopes, the number of neutrons in the isotopes varies greatly. Note that, the proton number of an atom determines its atomic number.

10. B.
Quarks are sub-atomic particles which are usually find inside the proton an the neutron which are located in the nucleus of an atom. High energy electrons and accelerators are usually used to study this sub particles. The electrons which orbit round the nucleus do not have quarks in their interiors.

How to determine if the ionic bond between lithium fluoride is stronger or weaker than the ionic bond in magnesium oxide?
lara [203]

Explanation:

As we know that the atomic number of lithium is 3 and its electronic distribution is 2, 1. Whereas atomic number of fluorine is 9 and its electronic distribution is 2, 7. So, for a metal it is easier to lose an electron rather than losing 2 or more number of electrons.

Also, fluorine is much more electronegative in nature. Hence, it will readily accept an electron from a donor atom. Therefore, a strong ionic bond will be present between lithium and fluorine atom.

On the other hand, atomic number of magnesium is 12 and its electronic configuration is 2, 8, 2. And, atomic number of oxygen is 8 and its electronic distribution is 2, 6. Also, oxygen is less electronegative than fluorine therefore, force of attraction exerted by oxygen to gain the valence electrons will not be strong enough.

Hence, the ionic bond between magnesium oxide is not strong enough.  

Thus, we can conclude that ionic bond between lithium fluoride is stronger than ionic bond in magnesium oxide.
