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.

Magnesium hydroxide (Mg(OH)2): g/mol
Eva8 [605]

To determine the molar mass, you need to get the atomic mass of the molecule. To do this, check the periodic table for the atomic mass or average atomic weight of each element.

Mg = 24.305 x 1 = 24.305 amu

O = 15.9994 x 2 =31.9988 amu

H = 1.0079 x 2 = 2.0158 amu

 

Then, add all the components to get the atomic mass of the molecule.

24.305 amu + 31.9988 amu + 2.0158 amu = 58.3196 amu


The atomic mass is just equivalent to its molar mass.

So, the molar mass of Magnesium hydroxide (Mg(OH)2) is 58.3196 g/mol.

Determine the equilibrium constant, Kp, for the following reaction, by using the two reference equations below: 2 NO(g) + O2(g)
klio [65]

Answer:

Kp=3.07x10^6

Explanation:

Hello,

In this case, by knowing the given reference reactions, one could rearrange them as follows:

2 NO(g) \leftrightarrow N_2(g) + O_2(g); Kp_2 = \frac{1}{2.3 x 10^{-19}}=4.35x10^{18}

N_2(g) + 2O_2(g) \leftrightarrow 2NO_2(g);Kp_3=(8.4x10^{-7})^2=7.056x10^{-13}

Subsequently, to obtain the main reaction, we add the aforementioned reference rearranged reactions as shown below (just as reference):

2NO(g)+N_2(g)+2O_2\leftrightarrow 2NO_2(g)+N_2+O_2

Consequently, the equilibrium constant is computed as:

Kp=\frac{[N_2][O_2]}{[NO]^2} * \frac{[NO_2]^2}{[N_2][O_2]^2} =Kp_2*Kp_3=4.35x10^{18}*7.056x10^{-13}=3.07x10^6

Best regards.
