Answer:

Cl

Si

Mg

Na

Explanation:

Ionization energy is the energy required to remove an electron from the valence shell of an atom to form an ion. Since metal are natural givers, they help people. Non metals are receivers hence it would be very hard for them to release their electrons.

For our arrangement, the key is that the ionization energy is expected to increase across the period to a maximum that terminates at the halogens. This is the more reason why halogens have the highest ionization energy and the alkali metals have the lowest.

Hence, from the options in the question, we can see that chlorine would have the highest because it is an halogen in group 17. Also expected is the fact that the ionization energy of that Mg is greater than that if Na. This is because Mg comes after Na in the same period and is thus expected to have higher ionization energy than Na

The water lattice: a. is formed from hydrophobic bonds. b. causes ice to be denser than water. c. causes water to have a relativ
Alexus [3.1K]

Answer: Option (d) is the correct answer.

Explanation:

It is known that water loving bonds are called hydrophilic bonds and water hating bonds are called hydrophobic bonds. Since, water is a polar solvent and it is only able to dissolve polar molecules and not non-polar molecules.

Lattice of water and hydrogen bonding are responsible for the various properties of water like cohesion, adhesion, heat of vaporization etc.

Thus, we can conclude that water lattice excludes non-polar substances.

In the first step of the reaction, which compound is the limiting reagent: sodium hydroxide or the nucleophile
anastassius [24]
Since the nucleophile is the actual attacking molecule or molecule that starts the reaction and allows for further steps in the mechanism to occur, it is the limiting reagent, as based on the amount of the nucleophile you have, the reaction will tend to proceed until you run out. The excess would be the sodium hydroxide, it is union part of the solution.

How many hours will it take for the concentration of methyl isonitrile to drop to 15.0 % of its initial value?
SpyIntel [72]

Answer:

The concentration  of methyl isonitrile will become 15% of the initial value after 10.31 hrs.

Explanation:

As the data the rate constant is not given in this description, However from observing the complete question  the rate constant is given as a rate constant of 5.11x10-5s-1 at 472k .

Now the ratio of two concentrations is given as

ln (\frac{C}{C_0})=-kt

Here C/C_0 is the ratio of concentration which is given as 15% or 0.15.

k is the rate constant which is given as 5.11 \times 10^{-5} \, s^{-1}

So time t is given as

ln (\frac{C}{C_0})=-kt\\ln(0.15)=-5.11 \times 10^{-5} \times t\\t=\frac{ln(0.15)}{-5.11 \times 10^{-5} }\\t=37125.6 s\\t=37125.6/3600 \\t= 10.31 \, hrs

So the concentration will become 15% of the initial value after 10.31 hrs.
