No, it doesn't. According to huckle rule it must have 14 \pi<span> electrons to be aromatic but it has only 12 pi electrons. then how does it follow the rule?

I hope my answer has come to your help. Thank you for posting your question here in Brainly. We hope to answer more of your questions and inquiries soon. Have a nice day ahead!

Water could be made to boil lower than its normal boiling point of 100 degrees Celsius at 92 degrees Celsius by?
KonstantinChe [14]
Water could be made to boil lower than its normal boiling point of 100 degrees Celsius at 92 degrees Celsius by lowering the atmosphere or external  pressure.

The boiling point is the temperature at which the vapor pressure of liquid equals the external or atmosphere pressure.

So, if you decrease the external pressure the temperature needed for the liquid reach the lower external pressure is also lower..


You can accomplish by taking the water to higher levels in the Earth (atmosphere pressure at high altitudes is lower than at sea level) or by creating vaccum.

Mg(OH)2 is a sparingly soluble salt with a solubility product, Ksp, of 5.61×10−11. It is used to control the pH and provide nutr
Solnce55 [7]

Answer:

The ration of the molar solubility is 165068.49.

Explanation:

The solubility reaction of the magnesium hydroxide in the pure water is as follows.

Mg(OH)_{2}\Leftrightarrow Mg^{2+}(aq)+2(OH)^{-}(aq)

              [Mg^{2+}][OH^{-}]

Initial      0          0

Equili     +S       +2S

Final      S          2S

K_{sp}=[Mg^{2+}][OH^{-}]

5.61\times 10^{-11}=(S)(2S)^{2}

S=(\frac{5.61\times 10^{-11}}{4})^{1/3}=2.41\times 10^{-4}M

Solubility of Mg(OH)_{2} in 0.180 M NaOH is a follows.

Mg(OH)_{2}\Leftrightarrow Mg^{2+}(aq)+2(OH)^{-}(aq)

              [Mg^{2+}][OH^{-}]

Initial      0          0

Equili     +S       +2S

Final      S          2S+0.180M

K_{sp}=[Mg^{2+}][OH^{-}]

5.61\times 10^{-11}=(S)(2S+0.180)^{2}

S=1.46\times 10^{-9}M

Ratio\,of\,solubility=\frac{2.41\times 10^{-4}}{1.46\times 10^{-9}}=165068.49

Therefore, The ration of the molar solubility is 165068.49.

4.) The temperature of solid silver increases from 30C to 40C by the addition of 117.5
Artyom0805 [142]

Answer:

The mass of silver is 49 g (0.049 kg).

Explanation:

Initial temperature = 30^{o}C

Final temperature = 40^{o}C

Quantity of heat required = 117.5 J

Specific heat capacity of silver = 0.240 J/g^{o} C

mass of the silver can be determined by;

Q = mcΔθ

Where: Q is the quantity of heat required, m is the mass of substance, c is the specific heat capacity of the substance and Δθ is the change in temperature.

So that,

117.5 = m x 0.240 x (40 - 30)

117.5  = m x 0.24 x 10

        = 2.4m

m = \frac{117.5}{2.4}

   = 48.9583

m ≅

m = 49 g

The mass of silver is 49 g (0.049 kg).
