Radda [10]3 years ago
5 0

Answer:  None of the given options .

Explanation:  The chemical formula of Iron (II) hydroxide can be written as

Fe (OH)2

As iron is present in its +2 state and hyrdoxide ion has charge of one negative unit .

Thus iron hydroxide can be written as the above and none of the given options is correct.

Arrange the following molecules according to the strength of their dispersion forces. Organize in order from largest to smallest
ki77a [65]

Explanation:

The weak intermolecular forces which can arise either between nucleus and electrons or between electron-electron are known as dispersion forces. These forces are also known as London dispersion forces and these are temporary in nature.

Therefore, more is the surface area occupied by the carbon chain more will be the dispersion forces present in it. Hence, less is the surface area occupied by a molecule less will be the dispersion forces present in it.  

Hence, the given molecules are organized from largest to smallest dispersion forces as follows.

CH_{3}CH(CH_{3})C(CH_{3})_{2}CH_{2}CH_{3} > CH_{3}CH_{2}(CH_{2})_{4}CH_{2}CH_{3} > CH_{3}CH_{2}CH_{2}CH_{2}CH_{3} > CH_{3}C(CH_{3})2CH_{3} > CH_{3}CH_{2}CH_{3} > CH4

If two gases with pressures of 2 atm and 3 atm are mixed at a constant temperature, what will the total pressure be?
slamgirl [31]
If two gases with pressures of 2 atm and 3 atm are mixed at constant temperature, the total pressure will be the sum of the two pressures. Therefore the answer is D. 2 atm + 3 atm or 5 atm will be the total pressure of the gas mixture.

Zinc has an average atomic mass of 65.37 amu. Jack is trying to figure out what the most abundant isotope of zinc is, but he doe
Mekhanik [1.2K]

Zinc's most abundant isotope : Zinc-65

<h3>Further explanation </h3>

Isotopes are atoms whose no-atom has the same number of protons while still having a different number of neutrons.

So Isotopes are elements that have the same Atomic Number (Proton)

Atomic mass is the average atomic mass of all its isotopes

In determining the mass of an atom, as a standard is the mass of 1 carbon-12 atom whose mass is 12 amu

Mass atom X = mass isotope 1 . % + mass isotope 2.%

To decide zinc's most abundant isotope, then choose the closest mass number

or we can check the difference with the average mass number, if the value is the smallest, then that isotope has the largest abundant

  • Zinc-64

\tt \dfrac{65.37-64}{65.37}=0.021

  • Zinc-65

\tt \dfrac{65.37-65}{65.37}=0.005

  • Zinc-68

\tt \dfrac{68-65.37}{65.37}=0.04

  • Zinc-66

\tt \dfrac{66-65.37}{65.37}=0.009

The closest = Zinc-65(the smallest)
