What else can I help you with?
Is it true that a change in pressure may affect the equilibrium position but has no effect on the equilibrium constant?
Yes, a change in pressure may affect the equilibrium position by shifting the reaction towards the side with more moles of gas to relieve the pressure change, but it has no effect on the equilibrium constant because the equilibrium constant is determined solely by the reaction's intrinsic properties.
What trend does electronegativity follow?
In electronegativity, the first ionization energy increases as it moves from left to right across a period . The nuclear charge also increases and the shielding effect is constant when moving across.
What role does the gas constant play in the Arrhenius equation for calculating reaction rates?
The gas constant in the Arrhenius equation helps to account for the effect of temperature on reaction rates. It is a constant value that relates the energy of the reacting molecules to the rate of the reaction.
Why dielectric constant of polyethylene is independent of temperature?
it is a polymer in which their is no induction effect and no dipoles are formed within the molecules as all the bonds are of equal strength and therefore no polymerization occurs in contrast to molecules such as pvc
Will rubber show tyndall effect?
No, rubber does not show the Tyndall effect. The Tyndall effect is the scattering of light by colloidal particles or particles suspended in a transparent medium, which causes the light to be visible as a beam. Rubber does not have the scattering properties required to exhibit this effect.
Why does the bigger size atoms have more sheilding effect?
The number of electron shells is higher.
What is a trend of sheilding effect in periods?
The shielding effect in periods refers to the decrease in the shielding effect as you move across a period from left to right. This is because the number of protons in the nucleus increases, resulting in a stronger positive charge that pulls the electrons closer to the nucleus, reducing the shielding effect. This leads to a stronger attraction between the nucleus and the outermost electrons.
Which of these causes global winds to appear to turn instead of blow straight across the earth's surface?
The Coriolis effect causes global winds to appear to turn instead of blowing straight across the Earth's surface. This effect is the result of the Earth's rotation and causes moving air or water to be deflected to the right in the Northern Hemisphere and to the left in the Southern Hemisphere.
Which of these causes global winds to appear to turn instead of blow straight across the earths surface?
Coriolis effect
What motion causes the Coriolis effect on earth?
The rotation of the Earth on its axis causes the Coriolis effect. As the Earth rotates, objects moving across its surface appear to curve due to the difference in linear velocity at different latitudes. This effect influences global wind patterns and ocean currents.
What is the consequeces of sheilding effect?
The shielding effect in chemistry refers to inner electrons shielding outer electrons from the attraction of the nucleus in an atom. This results in a decrease in the effective nuclear charge felt by the outer electrons, leading to changes in atomic and chemical properties such as ionization energy and atomic size in elements across a period.
Reducing the current you a circuit causes what?
Reducing the current to a circuit causes a higher resistance -- assuming constant Volts. Also, reducing the current to a circuit causes lower Volts -- assuming constant resistance.AnswerAltering the current has absolutely no effect on a circuit's resistance. Reducing the current will reduce line losses (I2R) and reduce the voltage drop along a conductor.
What is the uncertainty of a constant value?
It is the accuracy in the estimate of the constant or the effect of rounding.
Why sheilding effect makes cation formation easy?
The shielding effect reduces the effective nuclear charge felt by outer electrons, making them easier to remove. This lowered attraction between the nucleus and outer electrons facilitates the loss of electrons required for cation formation in atoms.
Can you give a sentence using the word constant?
The passage of time has a constant erosive effect.
is constant coughing a side effect?
5000
How a dynamo woks?
Dynamo has constant magnet inside.When movement comes up ,magnet starts turning .And outside of magnet has coiled wire .So this movement of magnet causes electromagnetic effect .Finally current consists with this electomagnetic effect.
