Since Oxygen is in group 16, this aspect has 6 valence electrons. Valence electrons choose to come to be as steady as feasible and comparable to a noble gas, which has 8 electrons. You need to find an element that will move its atoms to the oxygen to do 8 electrons. Looking in ~ the regular table, Selenium is in group 16 and will have 6 valence electron (6 + 6 = 12). This can"t move electrons through Oxygen. Hydrogen is in group 1 through 1 valence electron (6 + 1 = 7). This can"t transfer electrons with Oxygen. Strontium is in group 2 through 2 valence electron (6 + 2 = 8). This will carry electrons come Oxygen, making it the many stable.The ptcouncil.net is O and Sr.

Because the problem says valence electrons are transferred indigenous one atom come the other, it needs to be one "ionic" bond (it"s no the "covalent" bond due to the fact that electrons aren"t mutual with every other). Together a matter of fact, an "ionic" shortcut is developed when a metal combines v a non-metal or a metalloid. Strontium (Sr) is an alkaline planet metal, i m sorry is likewise a metal, and also Oxygen (O) is a non-metal. These 2 atoms will perfectly kind (an) "ionic" bond(s). Therefore, alternative (2) O and Sr is correct.Hope this would assist :))

What is the molarity the 10.0 g the NaCl liquified in water to do 100. ML?
tigry1 <53>

ptcouncil.net:

= 1.7 M

Explanation:

Molecular massive of NaCl = ( 23+35.5 ) = 58.5g

58.5g of NaCl are weighed by 1 mole the NaCl

10.0g that NaCl will certainly be sweet by ( 10÷58.5 )

= 0.17 mole of NaCl

100mL = ( 100÷1000)L = 0.1L

0.1L that a solution is lived in by 0.17 moles that NaCl

1L of equipment will be populated by <(1÷0.1)×0.17>

=1.7 M

The provided specie is a compound.

A compound is consisted of of two or an ext kinds the atoms/elements joined together in a definite grouping.

The nature of a compound are distinct and also different native those the the individual elements that are an unified in that is make-up. For this given specie, the facets are carbon, hydrogen and also oxygen. So, this is a compound.

Elements are distinct substances that cannot be break-up - increase into much easier substances. Such substances consist of only one kind of atom

Gnoma <55>

The offered question is incomplete. The complete question is as follows.

A solution of chloroform (

*
) and acetone (
*
) exhibits a negative deviation native Raoult"s law. This result implies that:

chloroform-chloroform interactions space stronger 보다 chloroform-acetone interactions.

chloroform-chloroform interactions space weaker than chloroform-acetone interactions.

acetone-acetone interactions space stronger 보다 chloroform-acetone interactions.

acetone-acetone interactions room weaker 보다 chloroform-acetone interactions

chloroform-chloroform interactions space weaker 보다 chloroform-acetone interactions and acetone-acetone interactions room weaker than chloroform-acetone interactions.

Explanation:

It is recognized that once the forces in between the particles of the mixture are stronger 보다 the forces in between the particles in the pure liquids then an unfavorable deviations indigenous Raoult"s regulation are observed.

Hence, once a systems of chloroform (

*
) and also Acetone (
*
) will exhibit a negative deviation from Roult"s law.

Then, chloroform-chloroform interactions have to be weaker 보다 chloroform-acetone interactions and also acetone-acetone interactions need to be weaker than Chloroform-Acetone interactions.

thus, we deserve to conclude that for the given case chloroform-chloroform interactions are weaker than chloroform-acetone interactions and acetone-acetone interactions room weaker than chloroform-acetone interactions.
