Determine the number of ions produced in the dissociation of the compound listed. MgBr₂

Chemistry
1 answer:
Ne4ueva [31]3 years ago
3 0

Explanation:

A dissociation reaction is defined as a reaction in which a compound dissociates into its constituent particles.

For example, MgBr_{2} \rightarrow Mg^{2+} + 2Br^{-}

For a neutral compound, it is required that the charges must be balanced between the combining atoms.

Here, MgBr_{2} is the neutral compound as charge +2 on one atom of magnesium is balanced by 2 atoms of Br^{-} ion.

Therefore, we can conclude that in total the number of ions produced in the dissociation of MgBr_{2} compound is 3.

Barium reacts with a polyatomic ion to form a compound with the general formula Ba3(X)2. What would be the most likely formula f
AfilCa [17]

Answer:

D. Na₃X

Explanation:

We have the neutral compound Ba₃(X)₂. <em>The total charge (zero) is equal to the sum of the charges of the ions times the number of ions in the molecule</em>.

3 × qBa + 2 × qX = 0

3 × (+2) + 2 × qX = 0

2 × qX = -6

qX = -3

If we have the cation Na⁺ and X³⁻, a neutral molecule would require 3 Na⁺ and 1 X³⁻. The resulting compound is Na₃X.

Calculate the number of moles of O2 gas held in a sealed 2.00 L tank at 3.50 atm and 25 ℃.
Leviafan [203]

Answer:

n=0.286mol

Explanation:

Hello,

In this case, we consider oxygen as an ideal gas, for that reason, we use yhe ideal gas equation to compute the moles based on:

PV=nRT\\\\n=\frac{PV}{RT}

Hence, at 3.50 atm and 25 °C for a volume of 2.00 L we compute the moles considering absolute temperature in Kelvins:

n=\frac{3.50atm*2.00L}{0.082\frac{atm*L}{mol*K}(25+273)K} \\\\n=0.286mol

Best regards.

What is the oxidation number of Cl in chlorate ion ClO3?
Kryger [21]

The correct answer to this question is "5." the oxidation number of cl in ClO3 will be a positive 5 because oxygen is naturally a -2 charge. times that by three and then account for the negative charge of the CLO3- ion.

Compare the change in pH with the addition of acid and base to deionized water and to a buffer.
iogann1982 [59]

Answer:

case1.

The addition of acid and base leads to a change in pH of the water when adding to deionized water due to fact that acid and bases dissociated in dissolving in water. If the H+ ion increases in the water as acid addition hikes it, it will result in decreasing the pH value. The intensity of the acid also affects the dissociation of the ions.

case2

Buffers are normally formed by weak acid and its conjugate base, and adding acid to the buffer it absorbs the H+ ions so the pH will be lower and adding base or increase of OH- conjugate base resists the pH value to increase.
