<h3>Answer;</h3>

Large

If a reaction is exothermic and produces large quantities of heat reaching equilibrium, its equilibrium constant will be large.

<h3>Explanation;</h3>

Chemical equations may either be exothermic or endothermic based on the energy changes in the reaction. Exothermic reactions are those reactions that loose heat energy to the surrounding, therefore the enthalpy change in these reactions is negative. Endothermic reaction on the other hand are those reactions in which energy is absorbed from the reaction thus their enthalpy is positive.
Chemical equilibrium in chemical reactions occurs when the rate of forward reaction is equal to the rate of reverse reaction. Equilibrium constant is the value of the chemical reaction quotient when the equilibrium of a reaction is achieved.
If a reaction is exothermic and produces large quantities of heat in order to reach equilibrium then the equilibrium constant will be large.

The equilibrium constant will be lowered and the equilibrium will shift to the left if the heat being produced is not removed.

masya89 [10]

Answer:

That is a very broad question. One thing that does not seem to be considered is the depletion of the ozone layer at high altitudes.

In the 1960's chlorofluorcarbons (CFC,s) became popular as refrigerants, spray can propellants, etc. In January 1989 the Montreal Protocol was passed which has greatly reduced the use of these substances. However, it may be several decades before the ozone layer can be replaced and again absorb harmful ulraviolet rays that may be partly responsible for the increase in global warming.

(One chlorine atom at high altitudes can be responsible for the destruction of 100,000 molecules of ozone - catalytic reaction)

Four identical metallic spheres with charges of +8.2 µC, +9.0 µC, −7.8 µC, and −8.8 µC are placed on a piece of paper. The paper

tigry1 [53]

Answer:

a) 0.15 μC b) 9.4*10¹¹ electrons.

Explanation:

As the total charge must be conserved, the total charge on the spheres, after being brought to contact each other, and then separated, must be equal to the total charge present in the spheres prior to be put in contact:

Q = +8.2μC +9.0 μC +(-7.8 μC) + (-8.8 μC) = +0.6 μC

As the spheres are assumed perfect conductors, as they are identical, once in contact each other, the excess charge spreads evenly on each sphere, so the final charge, on each of them, is just the fourth part of the total charge:

Qs = Qt/4 = 0.6 μC / 4 = 0.15 μC.

b) As the charge has a positive sign, this means that each sphere has a defect of electrons.

In order to know how many electrons are absent in each sphere, we can divide the total charge by the charge of one electron, which is the elementary charge e, as follows:

$N =\frac{0.15e-6C}{1.6e-19C} = 9.4e11 electrons$

For years, marine scientist were mystified by sound waves detected by underwater microphones in the Pacific Ocean. These so-call

pychu [463]

Answer:

225 m

Explanation:

$f$ = Frequency of the T wave = 6.8 Hz

$v$ = Speed of sound in seawater = 1530 ms⁻¹

$\lambda$ = Wavelength of the T wave

we know that, frequency, speed and wavelength are related as

$wavelength = \frac{speed}{frequency}$

$\lambda = \frac{v}{f}$

Inserting the values, we get

$\lambda = \frac{1530}{6.8}\\\lambda = 225 m$

How can we reduce the ripple factor of a bridge recitifier from 0.48 to 0.1 approximately ?

padilas [110]

U can try to use capacitor , the value of capacitor depends on circuit

ripple factors signifies the ac components, by def its ratio of rms value of ac component to value of dc component
so in order to reduce use of a capacitor which denies the sudden changes in voltage, which is the charracteristic of Ac signals

hope this helps
