Answer:

The answer to your question is 80%

Explanation:

Data

mass percent of SO₄⁻²

molecule MgSO₄

Process

1.- Calculate the molecular mass of magnesium nitrate

molecular mass = (1 x 24) + (1 x 32) + (4 x 16)

= 24 + 32 + 64

= 120 g

2.- Calculate the molecular mass of sulfate ion

molecular mass = (1 x 32) + (4 x 16)

= 32 + 64

= 96

3.- Write a proportion to solve this problem

120 g of MgSO₄ ---------------- 100 %

96 g of SO₄⁻² --------------- x

x = (96 x 100) / 120

x = 80 %

When might a large volume of material have little mass

Natali5045456 [20]

A large volume of material will have a small amount of mass when the material in question is gaseous or porous, and therefore has a lot of space within it despite taking up a large amount of space overall.

Start with 100.00 mL of 0.10 M acetic acid, CH3COOH. The solution has a pH of 2.87 at 25 oC. a) Calculate the Ka of acetic acid

jasenka [17]

Answer: a) The $K_a$ of acetic acid at $25^0C$ is $1.82\times 10^{-5}$

b) The percent dissociation for the solution is $4.27\times 10^{-3}$

Explanation:

$CH_3COOH\rightarrow CH_3COO^-H^+$

cM 0 0

$c-c\alpha$ $c\alpha$ $c\alpha$

So dissociation constant will be:

$K_a=\frac{(c\alpha)^{2}}{c-c\alpha}$

Give c= 0.10 M and $\alpha$ = ?

Also $pH=-log[H^+]$

$2.87=-log[H^+]$

$[H^+]=1.35\times 10^{-3}M$

$[CH_3COO^-]=1.35\times 10^{-3}M$

$[CH_3COOH]=(0.10M-1.35\times 10^{-3}=0.09806M$

Putting in the values we get:

$K_a=\frac{(1.35\times 10^{-3})^2}{(0.09806)}$

$K_a=1.82\times 10^{-5}$

b) $\alpha=\sqrt\frac{K_a}{c}$

$\alpha=\sqrt\frac{1.82\times 10^{-5}}{0.10}$

$\alpha=4.27\times 10^{-5}$

$\% \alpha=4.27\times 10^{-5}\times 100=4.27\times 10^{-3}$

Select the substance that is thought to be partially responsible for depleting the concentration of ozone in the stratosphere. s

gogolik [260]

Answer:

cfcl3

Explanation:

When the cfcl3 in the atmosphere is hit by UV rays from the sun, it decomposes to Cl atoms. These Cl atoms then react with the ozone producing O2 and ClO. The ClO bombard with O atoms splitting the ClO up and the free Cl atom again bonds to another O3 molecule hence reducing it. One ClO can reduce several O3 molecules (up to 100,000) creating an ozone hole.

2Cl + O3 → 2ClO + 2O2

2ClO + 2O → 2Cl + 2O2
