Answer:

Empirical formula is SeBr₄

Explanation:

Given data:

Mass of selenium = 7.928 g

Mass of bromine = 32.072 g

Empirical formula = ?

Solution:

Number of gram atoms of Se = 7.928/ 78.96 = 0.1

Number of gram atoms of Br = 32.072 / 79.9 = 0.4

Atomic ratio:

Se : Br

0.1/0.1 : 0.4/0.1

1 : 4

Se : Br = 1 : 4

Empirical formula is SeBr₄

A student in chm 11500 lab measured the mass of a 250-ml erlenmeyer flask and recorded it as 79. 83 g. She added 10. 00 ml of de

An Erlenmeyer flask is also termed as conical flask and titration flask. Invented in the year 1860. It is made up of glass and plastic. Inventer - Emil Erlenmeyer

Weight of empty erlenmeyel flask = 79.83 g

Weight after addition of water = 89.82 g

Weight of water = 89.82 - 79.83 = 9.99 g

Density of water at 22 deg celcius = 0.99777

Density = mass / volume

Volume = mass / density

= 9.99 g / 0.99777 g/ ml

= 10.01 ml

Calculated volume of water that the student measured is 10.01 ml.

The solubility product for Zn(OH)2 is 3.0×10−16. The formation constant for the hydroxo complex, Zn(OH)2−4, is 4.6×1017. What is

Yuri [45]

Answer:

$[OH^-]= 1.12 \times 10^{-2} \ M$

Explanation:

$\text{From the information given:}$

$K_{sp} \ of \ Zn(OH)_2 \ is \ 3.0 \times 10^{-16}$

$K_f \ of \ Zn(OH)_2 = 4.6 \times 10^{17}$

$\mathtt{K_{sp} \ \ \ \ \ \ \ \ \mathtt{Zn(OH)_{2(s)}} \to Zn^{2+}_{(aq)} + 2OH^{-}_{(aq)} }$

$\mathtt{K_{f} \ \ \ \ \ \ \ \ \mathtt{Zn^{2+}_{(aq)} } + 4OH^-_{(aq)} \to Zn(OH)^{2-}_{4}_{(aq)}}$

$\mathtt{K \ \ \ \ \ \ \ \ \mathtt{{Zn(OH)_{2}_{(s)}}} + 2OH^{-}_{(aq)} \to Zn(OH)^{2-} _{4(aq) }}$

$\text{To calculate the minimum concentration of OH}^{-}$

$K = \dfrac{Zn(OH)^-_4}{[OH^-]^2} \\ \\$

$[OH^-]^2= \dfrac {0.017}{1.380 \times 10^2}$

$[OH^-]^2=1.232 \times 10^{-4}$

$[OH^-]= 1.12 \times 10^{-2} \ M$

KATRIN_1 [288]

It's the outermost layer of atmosphere, it's thin, but it's said to absorb harmful radiation coming from the Sun, which is really important considering Sun's radiation could melt down the DNA of almost all form of life.
