This problem is asking for the major alkyne product that is formed when 1,1‑dichloro‑3‑methylbutane reacts with sodium amide (NaNH₂) ignoring any byproduct.

Thus, we can firstly say that such reaction of an alkyl halide with a strong base such as sodium amide is able to remove the halogen-based substituents and hence form insaturations in the form of double or triple bonds depending on the degree of substitution.

For instance, if one halogen substituent, then an alkene will be formed; but if two, then an alkyne (like this problem).

In such a way, as shown on the attached figure, the product will be 3-methylbutyne due to the loss of two chlorine substituents.

4 molecules

Explanation:

In the products side of the equation, you see 4N2, this means there are 4 molecules of N2 that are produced by the reaction.

When energy is added to a system during phase change, the particles move faster.

When a substance is heated, the internal energy within a system associated with the motion of particles and that can be added to a substance is called thermal energy.

During a phase change, when more energy is added to the system, the particles within the system will have greater motion and the temperature will increase.

The attractions that hold molecules together are electrostatic forces. The correct statement about the attractions that hold particles is that attractions between particles break when  attractions due to Electrostatic forces when particles move fast enough these forces can no longer keep particles together.

Rubber band  is not a perfect comprehension for Bonds in a substance when considering phases change because for a phase change from liquid to gas the bonds do not break completely the particles can still slide past each other.

When radioactive decay occurs, the original nucleus splits into daughter nuclei and the resulting nucleus is more stable than the original nucleus. The nucleus can be of a different element than the original.

Unstable nuclei often undergo radioactive decay. In a radioactive decay, the unstable nucleus is broken up into other nuclei. Usually, the nuclei formed during radioactive decay are smaller in mass compared to the original nucleus.

Also, the resulting nucleus is more stable than the original nucleus. The nucleus can be of a different element than the original.

Answer:

54.75 mL

Explanation:

First calculate the number of moles of NaCl in the 150mL solution of NaCl

0.0365 moles should be present on 1000cm3 or 1dm3 of water.

1L = 1 dm3

1 mL = 1 / 1000 dm3

150 mL = 150/1000 dm3 = 0.15 dm3

If x moles are present in 0.15 dm3,

x/ 0.15 = 0.0365

We get x= 0.0365 × 0.15 mol

Now x amount of moles should be taken from the initial 0.100 M NaCl solution

So 0.1 moldm-3 = 0.0365× 0.15 mol / V

we get V = 0.05475 dm3

V= 0.05475 L

V= 54.75 mL

It's easier to answer what makes it unsaturated.

H - C ≡ C - H

This is Acetylene. It has three shared bonds between the two carbons. That many bonds makes it unsaturated.

     H   H

H - C - C - H

     H   H

Draw lines from 1 H on top to the Carbon underneath Do the same with the other hydrogen. Make the two Hydrogens on the bottom do the same thing.

The point is that Carbon has 4 bonds. 1 bond goes to the other Carbon. The other 3 take on Hydrogen. That molecule is saturated: nothing can be added in its natural state.

Answer:

a) That of Al is higher than that of Mg because Mg wants to lose the second electron, so it is easier to take the second electron away

Statement which is true regarding second ionization energy is that ionization energy of of Al is higher than that of Mg because Mg wants to lose the second electron, so it is easier to take the second electron away.

Ionization energy is defined as the minimum amount of energy required to remove an electron which is loosely held in the outermost shell to form an isolated gaseous atom,ion or molecule.

It has a positive value for neutral atoms indicating that the ionization process is an endothermic process . The closer the outermost shell electrons are to the nucleus of an atom higher is it's ionization energy.It is expressed in electron volts or joules.

Ionization energy increases across period as more energy is required to remove electron from an atom as it is closely held along a period while it is decreasing down the group as on going the group the inter-nuclear distance increases and as a result less energy is required to remove an electron.

Static electricity is the result of an imbalance between negative and positive charges in an object. ... When two materials are in contact, electrons may move from one material to the other, which leaves an excess of positive charge on one material, and an equal negative charge on the other.

Answer: 1) Contact between two substances.

Explanation:

#1 When fuel is running through pipes, there is a lot of contact between the fuel and the pipe.

#2 Before, people thought that Static at first was caused by friction, meaning the rubbing (of an object, pause) had something to do with static.

Answer:

The edge of boiling over of the substance relies upon the strength of holding between the particles, unequivocally the intermolecular powers between the atoms. The intermolecular powers that exist between the particles relies upon the idea of the atoms like extremity, sub-atomic weight, design of the atom, and so forth In testing the edge of boiling over of the two given fluids, the expansion in edge of boiling over can be noticed for the compound with higher limit. This demonstrates that there is lower intermolecular power in the compound with lower atomic weight.

Explanation:

Hope this helps

The strength of holding between the particles, namely the intermolecular forces between the atoms, determines the substance's edge of boiling over. The intermolecular forces between the particles depend on concepts related to atoms, such as extremities, sub-atomic weight, atom design, and so on.

Each atom is made up of a nucleus and one or more electrons that are linked to it. One or more protons and a significant number of neutrons make up the nucleus. Only the most prevalent type of hydrogen is neutron-free. Atoms that are neutral or ionized make up every solid, liquid, gas, and form of plasma.

But when it comes to the name atom, we must travel back to 400 B.C. ancient Greece. The Greek word atomos, which meaning "uncuttable," was proposed by Democritus, a renowned philosopher. In the end, all matter could be reduced to distinct, tiny particles, or atomos, he said.

When the two supplied fluids' edges of boiling over are tested, the compound with the greater limit exhibits an expansion in the edge of boiling over. This illustrates that the compound with a lower atomic weight has a lower intermolecular power.

Thus,The intermolecular forces between the particles depend on concepts related to atoms.

Answer:

A cation with a 2+ charge will make a stronger ionic bond than a cation with a 1+ charge. A larger ion makes a weaker ionic bond because of the greater distance between its electrons and the nucleus of the oppositely charged ion.
