Answer:

5.6L of O2 means we have 0.25 moles of O2. and as 1 molecule of O2 has 2 atoms, so, 1.50575*10^23 molecules will have 2*1.50575*10^23 atoms=3.0115*10^23 atoms of O.

5.6L of O2 means we have 0.25 moles of O2.
As, 1 mole has 6.023*10^23 molecules,
0.25 moles of O2 will have 0.25*6.023*10^23 molecules=1.50575*10^23 molecules
and as 1 molecule of O2 has 2 atoms, so, 1.50575*10^23 molecules will have 2*1.50575*10^23 atoms=3.0115*10^23 atoms of O.

Adipic acid, C6H10O4, is a raw material for the making of nylon and it can be prepared in the laboratory by the following reacti

Dafna1 [17]

Mass of Cyclohexen : 10.2 g

<h3>Further explanation</h3>

Reaction

3 C6H10 + 4 Na2Cr2O7 + 16 H2SO4 >

3 C6H10O4 + 4 Cr2(SO4)3 + 4Na2SO4 + 16 H2O

mol C6H10 : mol C6H10O4 = 3 : 3 = 1 : 1

$\tt \%yield=\dfrac{actual}{theoretical}\times 100\%\\\\68.6\%=\dfrac{12.5}{theoretical}\times 100\%\\\\theoretical=18.22~g$

12.5 grams of C6H10O4 , mol C6H10O4 (MW 146.14 g/mol):

$\tt \dfrac{18.22}{148}=0.123$

mol C6H10 = mol C6H10O4 = 0.124

mass C6H10 :

$\tt 0.124\times 82.16=10.2~g$

Solid calcium oxide reacts with sulfur trioxide gas to produce solid calcium sulfate

antiseptic1488 [7]

Answer: The chemical equation for the given reaction is given below.

Explanation:

When solid calcium oxide reacts with sulfur trioxide gas to produce solid calcium sulfate, the chemical equation follows:

$CaO(s)+SO_3(g)\rightarrow CaSO_4(s)$

This is the reaction when a metal oxide reacts with non-metal oxide to produce a salt.

By Stoichiometry of the reaction:

1 mole of solid calcium oxide reacts with 1 mole of sulfur trioxide gas to produce 1 mole of solid calcium sulfate.

Which substance is a product of a fermentation reaction?glucosezymaseethanolwater?

Makovka662 [10]

Answer is: a product of a fermentation reaction is ethanol (C₂H₅OH).
Fermentation is a metabolic process in which ethanol is produced from sugar in the absence of oxygen (anaerobic digestion).
Fermentation occurs in yeast, bacteria and in oxygen-starved muscle cells.
Fermentation is a way of extracting energy from molecules and it is the oldest metabolic pathway.
