Answer:

Yes

Explanation:

The genetic testing is also called as the DNA testing. It is mainly used for identifying the changes in the DNA sequence or the chromosomes structure. It can also measure the results in the genetic changes.

Couples those who are planning to start a family should go for a genetic testing so as to minimize a risk in the upbringing or growth of their offspring. By doing a genetic testing a couple can well know the conditions of the baby that could affect them. The result from a genetic testing can help to plan better before starting a family. Therefore, it is advisable for couples to go for a genetic testing so that they plan better by knowing the conditions.

Because the the individual components of any mixture are not _____ to each other, the composition of those components can vary.
Alla [95]

Answer:

<em>Because the individual components of any mixture are not</em> <u>bonded</u> t<em>o each other, the composition of those components can vary. Also, some of the </em><u>physical</u> <em>properties of the individual components are still noticeable.</em>

Explanation:

A <em>mixture</em> is a combination of two or more pure substances that are present in any proportion and each pure substance keeps its own physical and chemical properties.

As oppossite to mixtures, the compounds are pure substances formed by two or more different elements which are chemically bonded to each other. So, while in the compounds the components (elements) are bonded in a fixed proportion, and their composition cannot vary, in the mixtures each component may be present in any proportion, which means that the <em>composition can vary</em>.

Take, for example, the simple case of talc and iron particles.This is <em>a mixture</em>. Talc is <u><em>not bonded</em></u> to the iron particles, and so their proportion, <em>the compositoin</em>, can vary in any form. Aslo, both talc and iron particles keep their own <u><em>physical properties</em></u>: you can perfectly separate the mixture by using a magnet to attract the iron particles, because they have not lost their magnetic property (a physical one).

Please explain how to find each answer solution.
svp [43]

Explanation:

1) Based on the octet rule, iodine form an <u>I</u>⁻ ion.

Therefore,

Option E is correct ✔

2) The electronic configuration of the sulfide ion (S²⁻) is :

₁₆S = 1s² 2s² 2p⁶ 3s² 3p⁴ or [Ne] 3s² 3p⁴

₁₈S²⁻ = 1s² 2s² 2p⁶ 3s² 3p⁶ or [Ne] 3s² 3p⁶

Therefore,

Option E is correct ✔

3) valence shell electron of

Halogens = 7

Alkali metal = 1

Alkaline earth metal = 2

Therefore,

Option D is correct ✔

4) Group 2 element lose two electron in order to achieve Noble gas configuration.

And here Group 2 element is Sr

Therefore,

Option B is correct ✔

5) Group 13 element lose three electron in order to achieve Noble gas configuration.

And here Group 13 element is Al

Therefore,

Option B is correct ✔

6) For a given arrangements of ions, the lattice energy increases as ionic radius <u>decreases</u> and as ionic charge <u>increases</u>.

Therefore,

Option A is correct ✔
