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

What is the bond angle of a methane molecule that contains four hydrogen atoms bonded to one carbon atom?
IRINA_888 [86]
Methane is a tetrahedral molecule where each C-H is kept as far away from the others as possible due to electron-electron repulsion, resulting in a bond angle of 109.5˚ (Technically 109˚ 28' but I would just use the decimal version if I were you).
Hope this helps!

If the concentration of mercury in the water of a polluted lake is 0.250 μg (micrograms) per liter of water, what is the total m
aleksandr82 [10.1K]

Answer:

142.36 kg

Explanation:

volume of water in the lake = surface area x depth

= 18.5 x ( 1760 x 3 )² x 39 ft³

= 2.011 x 10¹⁰ ft³

= 2.011 x 10¹⁰ x 28.3168 liter .

= 56.945 x 10¹⁰ liter .

concentration of mercury = .25 x 10⁻⁶ g / liter

= 25 x 10⁻⁸ g / liter

= 25 x 10⁻¹¹ kg / liter

mass of mercury in the water of lake

= 25 x 10⁻¹¹ x 56.945 x 10¹⁰ kg

= 142.36 kg .
