I think the correct answer is A. If one body is positively charged and another body is negatively charged, free electrons tend to move from the negatively charged body to the positively charged body. This happens because they have different charges and therefore electrons are more attracted to the positive or its opposite charge.

Determine the electron-group arrangement, molecular shape, and ideal bond angle for the following molecule: PH3 Electron-group a

Alecsey [184]

Answer:

The molecular shape and ideal bond angle of the $PH_{3}$ is trigonalbipyramidal and $109.5^{o}$ respectively.

Explanation:

The structure of $PH_{3}$ is as follows.(in attachment)

From the structure,

Phosphor atom has one lone pair and three hydrogens are bonded by six electrons.

Therefore, total electrons invovled in the formation $PH_{3}$ is eight.

Hence, four electron groups which indicate the tetrahedral shape. But one pair is lone pair i.e, present on the phosphor atom.

Therefore, ideal geometry of the $PH_{3}$ molecule is Trigonalbipyramidal.

The ideal angle of trigonalbipyrmidal is $109.5^{o}$ .

All three bonds of P-H has $109.5^{o}$ .

Therefore, ideal bond angle is $109.5^{o}$ .

For SCl4, the electron domain geometry is _______(i)________ and the molecular geometry is ______(ii)________.

Likurg_2 [28]

The electron domain geometry is trigonal bipyramidal while the molecular geometry of the compound is seesaw.

The shapes of molecules is determined by the number of electron pairs on the valence shell of the central atom in the molecule. These electron domains include lone pairs and bond pairs.

The lone pairs only contribute towards the electron domain geometry and not the molecular geometry. SCl4 has five electron domains hence its electron domain geometry is trigonal bipyramidal. The molecular geometry of the compound is seesaw.

3. Discuss the difference between molarity and molality, state the units of each, state the symbol for each, and give an example

dangina [55]

Molality(m) or molal concentration is a measure of concentration and it refers to amount of substance in a specified amount of mass of the solvent. Used unit for molality is mol/kg which is also sometimes denoted as 1 molal. It is equal to the moles of solute (the substance being dissolved) divided by the kilograms of solvent (the substance used to dissolve).

Molarity(M) or molar concentration is also a measure of concentration and represents the amount of substance per unit volume of solution(number of moles per litre of solution. Used unit for molarity is mol/L or M. A solution with a concentration of 1 mol/L is equivalent to 1 molar (1 M).

Molality is preferred when the temperature of the solution varies, because it does not depend on temperature, (neither number of moles of solute nor mass of solvent will be affected by changes of temperature), while molarity changes as temperature changes(volume of solution changes as temperature changes).
