According to the fact that  [H+]*[OH-] is always equal Kw= 1x10^(-14), you can easily find concentration of [H+] by changing from 1*10^(-9)to 1*10^(-11)
H increases, Kw is constant, therefore 10^-14 / 10^-11 = 10^-3.
And you will have Hence [H+] = 10^-3 where pH is 3

What happens when you put one hand in ice water and the other in warm water
NikAS [45]

When you put one hand in ice water and the other in warm water, the hand in warm water will feel the room temp water cooler, and the hand in cold water feel room temperature water warmer.

<h3>What is thermal adaptation?</h3>

The ability of a body to adjust to temperature is called thermal adaptation. Mammals are the animals who can adjust the temperature of their body.

The reptiles are not able to adjust their body temperature, because they are poikilothermic. They have to take the help of outer environment to adjust their body temperature.

Thus, when you put one hand in ice water and the other in warm water, the hand in warm water will feel the room temp water cooler, and the hand in cold water feel room temperature water warmer.

Help! help! plz give 4 different between orbit and orbital​
Gemiola [76]

Answer:

Differences between Orbit and Orbitals

Orbit

An orbit is the simple planar representation of an electron.

It can be simply defined as the path that gets established in a circular motion by revolving the electron around the nucleus

The shape of molecules cannot be explained by an orbit as they are non-directional by nature.

An orbit that is well-defined goes against the Heisenberg principle.

Orbital

An orbital refers to the dimensional motion of an electron around the nucleus in a three-dimensional motion.

An orbital can simply be defined as the space or the region where the electron is likely to be found the most.

The shapes of the molecules can be found out as they are directional by nature.

An ideal orbital agrees with the theory of Heisenberg’s Principles.

Of the following equilibria, only ________ will shift to the right in response to a decrease in volume. N2 (g) + 3H2 (g) 2NH3 (g
igomit [66]

Answer:

Of the following equilibria, only one will shift to the right in response to a decrease in volume.

N_2 (g) + 3H_2 (g)\rightleftharpoons 2NH_3 (g)

On decreasing the volume the equilibrium will shift in right direction due to less number of gaseous moles on product side.

Explanation:

Any change in the equilibrium is studied on the basis of Le-Chatelier's principle.

This principle states that if there is any change in the variables of the reaction, the equilibrium will shift in the direction to minimize the effect.

Decrease the volume

If the volume of the container is decreased , the pressure will increase according to Boyle's Law. Now, according to the Le-Chatlier's principle, the equilibrium will shift in the direction where decrease in pressure is taking place. So, the equilibrium will shift in the direction number of gaseous moles are less.

N_2 (g) + 3H_2 (g)\rightleftharpoons 2NH_3 (g)

On decreasing the volume the equilibrium will shift in right direction due to less number of gaseous moles on product side.

2 Fe_2O_3 (s) \rightleftharpoons 4 Fe (s) + 3O_2 (g)

On decreasing the volume the equilibrium will shift in left direction due to less number of gaseous moles on reactant side.

2 SO_3 (g) \rightleftharpoons 2 SO_2 (g) + O_2 (g)

On decreasing the volume the equilibrium will shift in left direction due to less number of gaseous moles on reactant side.

H_2 (g) + Cl_2 (g) \rightleftharpoons 2 HCl (g)

On decreasing the volume the equilibrium will shift in no direction due to same number of gaseous moles on both sides.

2HI (g) \rightleftharpoons H_2 (g) + I_2 (g)

On decreasing the volume the equilibrium will shift in no direction due to same number of gaseous moles on both sides.
