As the ph ________, the concentration of hydrogen ions increases, and the solution becomes ___________

Consider the reaction

andriy [413]

Answer:

Kp of the reaction is 0.0215

Explanation:

Step 1: Data given

Partial pressure at the equilibrium of N2 = 0.22 atm

Partial pressure at the equilibrium of O2 = 0.19 atm

Partial pressure at the equilibrium of NO = 0.030 atm

Temperature = 2200 °C

Step 2: The balanced equation

N2(g) + O2(g) ⇌ 2NO(g)

Step 3: Calculate Kp

Kp = (pNO)² /(pO2)*(pN2)

Kp = (0.030)²/(0.19*0.22)

Kp = 0.0215

Kp of the reaction is 0.0215

There are three different dichloroethylenes (molecular formula C₂H₂Cl₂), which we can designate X, Y, and Z. Compound X has no d

Alexxandr [17]

Compound X= (E)-1,2-dichloroethene

Compound Y= 1,1-dichloroethene

Compound Z= (Z)-1,2-dichloroethene

Elaboration :

In this case we will have 3 isomers which have the same formula. If we use the formula, the options we have are that the chlorides are attached to the same carbon (compound Y) or different carbons (Compounds X and Y).

Now, the problem gives a clue about compounds X and Y, hydrogenation results in the same compound (see figure) therefore the only difference between the compounds is the orientation of the Cl groups, therefore one of them it must be "E" and the other "Z" (this nomenclature should be used for alkenes, since the cis / trans nomenclature is used for other types of molecules),

so the question is which is the cis isomer and which is the Isomer Z ?

The problem says that compound X has no dipole moment, therefore in compound X the Cl groups must have opposite directions such that the dipole moments of both cancel each other out. In conclusion, compound X is the isomer E, compound Y is the compound in which the Cl groups are on the same carbon and compound z is the isomer Z.

So, yes Y will have a dipole moment

Dipole moment :

A dipole moment is a measurement of the separation of two opposite electrical charges. Dipole moments are a vector quantity. The magnitude is equal to the charge multiplied by the distance between the charges and the direction is from negative charge to positive charge: μ = q · r.

If 251 mL of 6.0 M H2SO4 is diluted to 500. mL, what is its new molarity?

kolezko [41]

Answer:

3.0M

Explanation:

The dilution formula is:

$M_1\times V_1=M_2\times V_2$

Where M₁ and M₂ are the molar concentrations and V₁ and V₂ are the volumes of the concentrated and the diluted solutions.

Substitute:

M₁ = 6.0M

M₂ = unknown

V₁ = 251 mL

V₂ = 500. mL

$6.0M\times 251ml=M_2\times 500.ml$

Clear M₂ and compute:

$M_2=6.0M\times 251ml/500.ml\approx3.0M$

Imagine you are about to investigate what happens when sodium and potassium are mixed together. Before you begin your experiment

inessss [21]

Explanation:

Potassium and Sodium are both metals on the periodic table. Both elements are found on the s-block of the table. Therefore, it is not possible for both of them to combine to form a compound.

For a compound to form two elements must combine in a definite order to given single product.

The combination is facilitated by a loss, gain or sharing of electrons between two species. This leads to an attraction between the combining species.

Both Sodium and potassium would prefer to lose electrons and there is no reason for them to combine to form a compound.

Explain why gases such as the oxygen found in tanks used as hospitals are compressed. why must care be taken to prevent compress

allochka39001 [22]

They are compressed so that a larger amount of gas can be stored in a smaller container. A greater mass confined to a smaller volume makes transporting and storing of gases easier. Increasing temperature increases pressure, and the cylinders might explode. Before compressed oxygen can be breathed, it must be decompressed.
