HELPPPP DOES ANYONE KNOW<br> 34<br> 35<br> 36<br> 37

Salsk061 [2.6K]

Answer:

34- Solid

35-Metals form metallic bonds releasing one or more valence electrons to form a common electron reservoir which contains free mobile elactrons who will conduct electricity well.

36 When the cation is formed electrons are removed and the effective positive neuclear charge increases and it makes the remaining electrons accumulate around the neucleous making the cationic radius smaller than that of the atom

A 1.50 L buffer solution is 0.250 M in HF and 0.250 M in NaF. Calculate the pH of the solution after the addition of 0.100 moles

alexgriva [62]

Answer : The pH of the solution is, 3.41

Explanation :

First we have to calculate the moles of $HF$ .

$\text{Moles of HF}=\text{Concentration of HF}\times \text{Volume of solution}$

$\text{Moles of HF}=0.250M\times 1.50L=0.375mol$

Now we have to calculate the value of $pK_a$ .

The expression used for the calculation of $pK_a$ is,

$pK_a=-\log (K_a)$

Now put the value of $K_a$ in this expression, we get:

$pK_a=-\log (6.8\times 10^{-4})$

$pK_a=4-\log (6.8)$

$pK_a=3.17$

The reaction will be:

$HF+OH^-\rightleftharpoons F^-+H_2O$

Initial moles 0.375 0.100 0.375

At eqm. (0.375-0.100) 0 (0.375+0.100)

= 0.275 = 0.475

Now we have to calculate the pH of solution.

Using Henderson Hesselbach equation :

$pH=pK_a+\log \frac{[Salt]}{[Acid]}$

$pH=pK_a+\log \frac{[F^-]}{[HF]}$

Now put all the given values in this expression, we get:

$pH=3.17+\log [\frac{(\frac{0.475}{1.50})}{(\frac{0.275}{1.50})}]$

$pH=3.41$

Thus, the pH of the solution is, 3.41

Explain how scientists use balanced chemical equations and molar mass concepts to represent reactions and account for the amount

konstantin123 [22]

Explanation:

Scientists most especially chemists use the mole concepts through balanced chemical equations and molar masses to represent chemical reactions and account for the amount of substances.

The mole concept entails finding molar relationships between reactants and products in a chemical reaction. Mole connects difference chemical parameters and it is used in quantitative analysis of chemical reaction.

First, we work from the known to the unknown.
The known is the specie whose mass or number of moles is given.

Number of moles = $\frac{mass}{molar mass}$

After obtaining the number of moles, then go ahead to compared using the balanced reaction with that of the unknown.
Then from them find the mass of the unknown.
