Is osmosis the same quality of diffusion but in different molecules

Provide only the major alkene product that results when n,n-dimethylhexan-2-amine undergoes cope elimination?

Fofino [41]

The major alkene product that results when n,n-dimethylhexan-2-amine undergoes cope elimination is hexene or hex-1-ene.

The reaction in which an amine is oxidize to an intermediate called an N-oxide which , when heated , acts as base in an intramolecular elimination reaction. The oxidation of tertiary amine into N-oxide is called cope reaction.

This elimination gives the less substituted alkene along with more substituted alkene which is Zaitsev product.

Example: Cope elimination of n,n-dimethylhexan-2-amine form hexene.

Answer: See explanation

Explanation:

The negative effects of video games include:

1. Social disconnection- One negative effect of video games is that it brings about social disconnection. Video games are typically addictive and this leads to the individual playing the game gradually disconnecting from the social life. Such people tends to play games rather than having conversations with their friends or family members.

2. Addiction - Video games are addictive which can lead to depression or bring about mental health disorder.

3. Wrong values - Some video games instill wrong values in children. Such values include violence, aggression and vengeance.

4. Negative academic achievement - Students who play video games a lot tend to have a negative academic achievement as the time they could have used in reading or studying is used for playing games and thus tends to have an effect on the performance in school.

5. Health hazards- Video games may lead to health hazards- such as nerve compression, obesity, and video-induced seizures.

The positive effect of video games are:

1. Problem solving - Video games train ones brain to be creative and also come up with solution to challenges.

2. Quick thinking - Video games help one to think quickly in order to solve challenges and overcome obstacles.

3. Create positive emotions - Easy games can bring about positive emotions and uplift ones mood, and help in promoting relaxation.

4. Stimulate learning - Playing video games can help an individual to learn new skills.

Answer:

a. $\bold{C_{6}H_{12}O_{6}\rightarrow 6CO_{2}+6H_{2}O}$

△H=−72 kcal

The energy required for production of 1.6 g of glucose is [molecular mass of glucose is 180 gm]

b.

$\bold{Fe_{2}(SO_{4})_{3}+3Ba(OH)_{2}\rightarrow 3BaSO_{4}+2Fe(OH)_{3}}$

The iron(III) ions and chloride ions remain aqueous and are spectator ions in a reaction that produces solid barium sulfate.

Car manufacturers are developing engines that use H₂ as fuel. In Iceland, Sweden, and other parts of Scandinavia, where hydroele

weeeeeb [17]

If the coulombs are supplied at 1.44 V, then 4.766 × 10¹¹ joules are produced.

(a) The reaction is

2H₂O + 2e⁻ → H₂ + 2OH⁻

According to the reaction, 2 moles of electrons flow per mole of reaction,

(b) Given

T = 25°C

Change Celsius into Kelvin

T = 25°C

= (25 + 273 ) K

= 298 K

<h3>What is Ideal Gas Law ?</h3>

It is expressed as

PV = nRT

Hence ,

n = $\frac{PV}{RT}$

= $\frac{(12)(3.5.10^{6} )}{(0.082057)(298)}$

= 1.7176 ×10⁶ mole

Now, From the given reaction we can say that ,1 mole of H₂ is produced by 2 moles of electron

Hence, 1.7176 × 10⁶ mole of H₂ is produced by

= 2 × 1.7176 × 10⁶ moles of electron

= 3.435 ×10⁶ moles of electron

We know that

charge = moles of electron × F

= (3.435 ×10⁶ × 96500) C

= 3.31 × 10¹¹ C

(c) We know that,

Voltage = $\frac{energy}{charge}$ = $\frac{J}{C}$

1.44 V = $\frac{energy}{3.31 . 10^{11} }$

Energy = 1.44 V × 3.31 × 10¹¹ C

= 4.766 × 10¹¹ Joules

Thus from the above conclusion we can say that, coulombs are supplied at 1.44 V, then 4.766 × 10¹¹ joules are produced.

Disclaimer : The question given was incomplete on portal, Here is the complete question.

Question : Car manufacturers are developing engines that use H₂ as fuel. In Iceland, Sweden, and other parts of Scandinavia countries, where hydroelectric plants produce inexpensive electric power, the H₂ can be made industrially by the electrolysis of water.

a) How many moles of electrons flow per mole of reaction ?

b) How many coulombs are needed to produce 3.53X10⁶ L of H₂ gas at 12.0 atm and 25°C.

c) If the coulombs are supplied at 1.44 V, how many joules are produced?
