How would an equation be written for the dissociation of ionic solutes in water?

Chemistry
1 answer:
tangare [24]4 years ago
3 0
1) Assume M refers to a general element and Z referes to other general element.

2) Assume the chemical formula of the ionic compound is MₓZₐ

3) Then the dissociaton would be written:


MₓZₐ → XMᵃ⁺ + AZˣ⁻

That means that the ionic compoud will lead to the X cations Mᵃ⁺ whose oxidation state are a+, and A anions Zˣ⁻ whose oxidation state is x⁻.

5) For example: MgBr₂ (aq) → Mg⁺² (aq) + 2Br⁻ (aq)


6) Explanation: since the water molecules are polar, they will surround (solvate) the three ions that form the compound MgBr₂, overcoming the electrostatic forces that hold together the atoms in the ionic lattice.

The equation X + Y 2Z has the rate law equation shown below. Which of the following statements best describes the relationship o
andreyandreev [35.5K]
The order of the reaction with respect to X is 2.
The statements given ;
1. As Concentration of X is in the rate law equation , changing X will have an effect on the rate of the equation.
2. Rate is proportional to X^2
So if concentration of X is doubled, then rate proportional to (2X)^2 = 4X^2
Rate therefore quadruples when X is doubled
This statement is correct
3. If we divide X/2 then the effect to the rate is (X/2)^2 = X/4 . This will reduce the rate by quarter not half . This statement is wrong.
4. If we multiply by 3
Then rate proportional to (3X)^2 = 9X^2
Rate increases by 9 times. This statement is wrong

How much energy does cameron need to add to raise the temperature of a 0.500-kg sample of silver from 200 k to 205 k? the specif
zzz [600]

energy to raise temperature is 590 J

Given:

mass of silver sample = 0.5 kg

initial temperature = 200 k

final temperature = 205 k

specific heat of silver = 236 j/kgk

To Find:

energy to raise temperature

Solution: The heat energy required to raise the temperature of of a substance through is called its specific heat capacity.

Q = cmΔt

where c= constant of proportionality, called specific heat capacity of the body

Q = mass x specific heat x ∆t

= 0.5 x 236 x ( 205-200 )

= 590 J

So, energy to raise temperature is 590 J

Classify the following substituents according to whether they are electron donors or electron acceptors relative to hydrogen by
igor_vitrenko [27]

Species that have a lone pair of electrons often donate electrons by resonance while substituents that are electron deficient take away electrons by resonance.

<h3>What is resonance?</h3>

The term resonace has to do with the movement of electron pairs in a molecule. Inductive effects has to do with the drawing of electron density towards an atom or bond.

The two effects depends on the nature of a substituent. For instance, species that have a lone pair of electrons often donate electrons by resonance while substituents that are electron deficient take away electrons by resonance.

The question is incomplete hence the exact nature of the substituents can not be determined.
