Talja [164]3 years ago

4 0

Explanation:

Given

mass (m) = 0.5 kg

velocity (v) = 15 m/s

Now

Kinetic energy

= 1/2 *m*v²

= 1/2 * 0.5 * 12²

= 0.5 *0.5 * 144

= 36 joule

hope it will help

Why is a cis-1,3-disubstituted cyclohexane more stable thanits<br> trans isomer?

anzhelika [568]

Answer:

Explanation has been given below

Explanation:

In diaxial conformation of cis-1,3-disubstituted cyclohexane, 4 gauche-butane interactions along with syn-diaxial interaction are present. Hence it readily gets converted to diequitorial conformation where no such gauche-butane interaction is present
In two possible conformations of trans-1,3-disubstituted cyclohexane, 2 gauche-butane interactions are present in each of them.
Hence cis-1,3-disubstituted cyclohexane exists almost exclusively in diequitorial form. But trans-1,3-disubstituted cyclohexane has no such option.

Trans-1,3-disubstituted cyclohexane experiences gauche butane interaction in each of the two conformations.
Therefore cis-1,3-disubstituted cyclohexane is more stable than trans conformation

Hypothesis: Explain the relationship between forward and reverse reactions at equilibrium and predict how changing the amount of

postnew [5]

Explanation:

forward reaction

a reaction in which reactent react to form product is known as forward reaction

reverse reaction

a reaction in which product react to form reactent is known as reverse reaction

At equilibrium stage

In a chemical equilibrium, the forward and reverse reactions occur at equal rates, and the concentrations of products and reactants remain constant. A catalyst speeds up the rate of a chemical reaction, but has no effect upon the equilibrium position for that reaction.

changing amount of reactent and product

lechatlier principle

" if you impose any change in concentration ( reactant or product) , temperature or pressure on chemical system, the system response in that way that opposes the change "
