Answer:

bonding capacity is based on the oxidation number. the pattern throughout families 1-2 and 13-18 is 12343210. depending on wether the elements in a family lose or gain 1-4 valence electrons is what determines the bonding capacity. for example, the elements in family one, or the Alkali family elements, lose one valence electron to become stable. this means the next outer shell has 8 valence electrons and is therefore stable. family two elements lose 2 valence electrons in order to have 8 on the outer shell. family thirteen elements lose 3 valence electrons. family fourteen can either lose or gain their four valence electrons as long as they end up with an outer shell with 8 valence electrons. family fifteen gains 3 valence electrons, 16 gains two, and 17 gains 1. family 18 doesn't lose or gain any since it is already stable. if an element loses valence electrons its oxidation number will be a positive 1,2,3, or 4. if an element gains valence electrons its oxication number will be a negative 1,2,3, or 4. the pattern of oxidation numbers is the same as the bonding capacity and it is +1,+2,+3,+4/-4,-3,-2,-1 or 0. basically if you can find the oxidation number then you can find the bonding capacity

A sample of metal has a mass of 24.54 g, and a volume of 5.02 mL. What is the density of this metal? g/cm

zmey [24]

Answer:

4.88 g / cm³

Explanation:

Density of a substance is given by the mass of the substance divided by the volume of the substance .

Hence , d = m / V

V = volume

m = mass ,

d = density ,

From the question ,

The mass of the metal = 24.54 g

The volume of the metal = 5.02 mL

Hence , by using the above formula ,and putting the corresponding values , the density is calculated as -

d = m / V

d = 24.54 g / 5.02 mL

d = 4.88 g /mL

The unit 1mL = 1 cm³

Hence ,

d = 4.88 g / cm³

The densevapor iodinee heptafluoride reacts rapidly with water to give a mixture of periodic acid and hydrofluoric acid .

erma4kov [3.2K]

Explanation:

When iodine heptafluoride reacts rapidly with water to give a mixture of periodic acid and hydrofluoric acid. Reaction equation for the same is as follows.

$IF_{7} + 6H_{2}O \rightarrow H_{5}IO_{6} + 7HF$

As it is given that there are $3.72 \times 10^{-2}$ moles of iodine heptafluoride are present. Molar mass of $IF_{7}$ is 259.9 g/mol. Molar mass of $HIO_{4}$ is 227.94 g/mol and molar mass of HF is 20.01 g/mol.

Now, according to the reaction equation $3.72 \times 10^{-2}$ M $IF_{7}$ gives $3.72 \times 10^{-2}$ M $H_{5}IO_{6}$ .

Also, the volume is given as 795 ml or 0.795 L (as 1 mL = 0.001 L).

Hence, calculate the concentration of $H_{5}IO_{6}$ into the solution as follows.

Concentration = $\frac{\text{no. of moles}}{volume}$

= $\frac{3.72 \times 10^{-2}}{0.795 L}$

= $4.7 \times 10^{-2}$ mol/L

or, = 0.047 M

Now, as 1 mol of $IF_{7}$ produces 7 mol HF. So, $7 \times 3.72 \times 10^{-2} = 26.04 \times 10^{-2}$ M HF.

Therefore, concentration of HF will be calculated as follows.

Concentration of HF = $\frac{0.2604}{0.795}$

= 0.33 M

Thus, we can conclude that concentration of periodic acid is 0.047 M and concentration of hydrofluoric acid is 0.33 M.

2) Gay-Lussac's law shows a direct relationship between temperature and

shusha [124]

Answer:

The correct option is (b) "pressure".

Explanation:

Gay-Lussac's law states that the pressure of an ideal gas is directly proportional to its temperature at constant mass and volume.

Mathematically, Gay-Lussac's law is as follows :

$P=kT$

$\dfrac{P_1}{T_1}=\dfrac{P_2}{T_2}$

Hence, the correct option is (b) "pressure".
