If three electrons are available to fill three empty 2p atomic orbitals, how will the electrons be distributed in the three orbi
Sedaia [141]
Think of it this way: say orbitals are boxes and each box can contain 2 electrons.

If there are 3 boxes forming one orbital, it takes 6 electrons to completely fill it. Since there's less than six, each box takes one electron, so there's 1 electron per orbital.

Why dose a small container have more pressure than a large container of both have the same amount of gas in them
Volgvan
Because in a smaller container, there is less room for the gas to exist. the gas much all push together closer to fit in the smaller container. as gas atoms, they have less room to bounce around. in a bigger container, it has more room to more and is less pressurized

If the [H+] is 3.5x10-4, what is the [OH-]?
slava [35]

Answer:

2.90 x 10⁻¹¹moldm⁻³

Explanation:

Given parameters:

[H⁺]  = 3.5 x 10⁻⁴mol/dm³

Unknown

[OH⁻]  = ?

Solution;

The ionic product of water can be used to solve this problem. It has been experimentally determined to be  1 x 10⁻¹⁴mol² dm⁻⁶

             [H⁺] [OH⁻]  = 1 x 10⁻¹⁴

Therefore;

             [OH⁻]   = \frac{1  x 10^{-14} }{H}    = \frac{1  x  10^{-14} }{3.5 x 10^{-4} }   = 0.29 x 10⁻¹⁰moldm⁻³

                                                            = 2.90 x 10⁻¹¹moldm⁻³

Do anyone know how to do question B
Over [174]

Answer:

a) IUPAC Names:

                   1) (<em>trans</em>)-but-2-ene

                   2) (<em>cis</em>)-but-2-ene

                   3) but-1-ene

b) Balance Equation:

                       C₄H₁₀O + H₃PO₄   →   C₄H₈ + H₂O + H₃PO₄

As H₃PO₄ is catalyst and remains unchanged so we can also write as,

                                    C₄H₁₀O   →   C₄H₈ + H₂O

c) Rule:

           When more than one alkene products are possible then the one thermodynamically stable is favored. Thermodynamically more substituted alkenes are stable. Furthermore, trans alkenes are more stable than cis alkenes. Hence, in our case the major product is trans alkene followed by cis. The minor alkene is the 1-butene as it is less substituted.

d) C is not Geometrical Isomer:

        For any alkene to demonstrate geometrical isomerism it is important that there must be two different geminal substituents attached to both carbon atoms. In 1-butene one carbon has same geminal substituents (i.e H atoms). Hence, it can not give geometrical isomers.

If we increase the temperature of the reaction that occurs in plants to create sugar. What direction does the equilibrium shift.
maxonik [38]

The reaction used to produce sugar in plants is Photosynthesis,

6CO₂ + 6H₂O + heat ⇆ C₆H₁₂O₆ + 6O₂↑

we can see that this reaction is endothermic, it absorbs heat to occur

If we were to add more heat or increase the temperature, the left side of the equilibrium will be able to react much more, which would produce more glucose (aka sugar)

Hence increasing the temperature will shift the equilibrium to the right or towards the Products
