Chemistry

Answer:

Both are unreactive.

Explanation:

Atom      Number of Electrons

 A                        2

 D                       10

The two atoms A and D are very stable and unreactive.

Valence electrons the outermost shell electrons in a neutral atom.

The number of valence electrons in A is 2

The number of valence electrons in D is 8

The atoms are stable and unreactive because for A, its two electrons are in the k-shell in which the maximum number of electrons here is 2. It has a noble configuration which makes it stable.

For atom D, the outermost electrons are in the L-shell in which the maximum number of electrons is 8. This also makes it stable and unreactive.

Both atoms will be reluctant to lose or gain electrons.

D Which compound is insoluble in water?
densk [106]

Answer:

Examples of substances insoluble in water: oil, acetone, ether

Explanation:

Such examples of substances are non-polar and do not dissolve in water (polar compound). The classic example is oil floating in water (this happens because oil has a lower density than water).

CH3CH2PH2 can be synthesized by an SN2 reaction. Draw the structures of the alkyl chloride and nucleophile that will give this c
Maru [420]

Answer:

The PH2 becomes attached to the alkyl halide with inversion of configuration

Explanation:

SN2 reaction involves the simultaneous attachment of the nucleophile as the leaving group departs. This leads to an inversion of configuration because the sterochemistry around the carbon bearing the leaving group is reversed. The reaction proceed via a crowded five coordinate transition state. Details are shown in the image attached.

Dinitrogentetraoxide partially decomposes into nitrogen dioxide. A 1.00-L flask is charged with 0.0400 mol of N2O4. At equilibri
artcher [175]

Answer:

Keq=0.866

Explanation:

Hello,

In this case, the undergone chemical reaction is:

N_2O_42NO_2

In such a way, since 0.0055 mol of N₂O₄ remains in the flask, one infers that the reacted amount (x) was:

x=0.04mol-0.0055mol=0.0345mol

In addition, the produced amount of NO₂ is:

2*0.0345mol=0.069mol

Finally, considering the flask's volume, the equilibrium constant is then computed as follows:

Keq=\frac{(2*0.0345M)^2}{0.0055M}=0.866

Best regards.
