In a sample of H2SO4 containing 200 sulfur (S) atoms, how many atoms of hydrogen (H) would there be?
Otrada [13]

In a sample of H2SO4 that contain 200 S atom the number of hydrogen atoms  would be 400  atoms

explanation

there are two moles of H2  in H2SO4 therefore by use of ratio between S:H2 which is 1:2 atoms therefore the atoms of hydrogen = 2 x200 = 400 atoms

Two common methods to generate an aldehyde is by oxidation of an alcohol and through ozonolysis.
kotykmax [81]

Answer:

<u>a</u><u>.</u><u> </u><u>True</u><u>.</u>

Explanation:

Only primary and secondary alcohols can oxidise to give an aldehyde. But a weak oxidizing agent must be used to prevent formation of a carboxylic acid or ketone.

weak oxidizing agents: Chromyl chloride, silver/oxygen/500°C

take an example of <u>e</u><u>t</u><u>h</u><u>a</u><u>n</u><u>o</u><u>l</u><u>:</u>

<u>{ \bf{CH _{3} CH_{2}OH \:  \:  \frac{Ag/O_{2} }{500 \degree C}  >  \:  \:CH _{3} CHO}}</u>

<u>{ \sf{CH _{3} CHO \:  \: is \: ethanal}}</u>

<u>B</u><u>y</u><u> </u><u>o</u><u>z</u><u>o</u><u>n</u><u>o</u><u>l</u><u>y</u><u>s</u><u>i</u><u>s</u><u>:</u>

Here, reactants are Ozone gas, Carbon tetrachloride at a temperature (<20°C), ethanoic acid, zinc and water.

take an example of propanol:

if it undergoes ozonolysis, it gives ethanal and methanal.

Convert 6.42 moles of H2O to molecules
Ivahew [28]

Answer:

3.87 x 10^24

Explanation:

Simply multiply the moles by avogadros number

6.42 moles of H2O x 6.022 x 10^23 molecules/1 mole of H2O = 3.87 x 10^24 molecules of H2O

What is the molarity of a solution of hf if 4.400 moles of hf are added to a container and filled with water to a final volume o
Natasha2012 [34]

Answer is: the molarity of a solution of HF is 0.73 M.

n(HF) = 4.400 mol; amount of hydrofluoric acid.

V(HF) = 6.00 l; volume of hydrofluoric acid.

c(HF) = n(HF) ÷ V(HF).

c(HF) = 4.400 mol ÷ 6.00 l.

c(HF) = 0.733 mol/l; molarity of a solution (hydrofluoric acid).
