Compare the forces of attraction between molecules in water, sugar and oxygen. Rank them in order from greatest to least. A) wat

VladimirAG [237]

Answer:

Option C, sugar, water, oxygen

Explanation:

Force of attraction leads to closer placing of atomic particles in any element or molecule. The higher the force of attraction, the more compact is the arrangement of the atomic particle.

Thus, in a solid the atomic particles are closely packed followed by a liquid and then a gas.

As we know sugar is solid, water is liquid and oxygen is gas.

Thus, forces of attraction between molecules of sugar will be the highest followed by water and then oxygen

Hence, option C is correct

Plants fertilized one per week with Super Plant Food Formula have been shown in testing to produce twice as much fruit as plants that are not.

That answer is the most scientific because it states the word "testing" and in science they do a bunch of test to make a scientific claim.

Volume of 1 mole of N2 at 30 c and 1.2 ATM

Mariana [72]

We should indicate first and foremost the assumption of ideal gas behavior so that we can use the ideal gas equation written below:

PV = nRT

For this problem,let's solve for V. Rearranging the equation,

V = nRT/P

Substituting the values,

V = (1 mol)(0.0821 L-atm/mol-K)(30 + 273 K)/1.2 atm
<em>V = 20.73 L of N₂ gas</em>

Answer : The molecular shape of $SO_3^{2-}$ is trigonal pyramidal and bond angle between O-S-O is

Explanation :

Lewis-dot structure : It shows the bonding between the atoms of a molecule and it also shows the unpaired electrons present in the molecule.

In the Lewis-dot structure the valance electrons are shown by 'dot'.

The given molecule is, $SO_3^{2-}$

As we know that sulfur has '6' valence electrons and oxygen also has '6' valence electron.

Therefore, the total number of valence electrons in $SO_3^{2-}$ = 6 + 3(6) + 2 = 26

According to Lewis-dot structure, there are 8 number of bonding electrons and 18 number of non-bonding electrons or lone pair electrons.

The Lewis-dot structure of $SO_3^{2-}$ is shown below.

Formula used :

$\text{Number of electron pair}=\frac{1}{2}[V+N-C+A]$

where,

V = number of valence electrons present in central atom

N = number of monovalent atoms bonded to central atom

C = charge of cation

A = charge of anion

Now we have to determine the hybridization of the given molecule, $SO_3^{2-}$

$\text{Number of electrons}=\frac{1}{2}\times [6+2]=4$

The number of electron pair are 4 that means the hybridization will be $sp^3$ and the electronic geometry of the molecule will be tetrahedral.

But as there are 3 atoms around the central sulfur atom, the fourth position will be occupied by lone pair of electrons. The repulsion between lone and bond pair of electrons is more and hence the molecular geometry will be trigonal pyramidal and the bond angle between O-S-O is less than $109.5^o$ due to repulsion between lone and bond pair of electrons.
