Hey bud !
You were close congrats !
the only problem i saw was the units part at the end.
remember volume is 3 dimensional
length width and height
so it is m^3

2. How will the equilibrium shift if the following changes are made? State if the reaction will shift

Kamila [148]

Please give me brainleist. :)

Answer:

2a. If the temperature is increased, the reaction will shift to the right in an attempt to release some of the heat. As the forward reaction loses heat while the reverse would create more heat.

2b. If the pressure is increased, it would shift to the left to counteract the increase in pressure as the left side will have fewer molecules.

2c. If Cl2 is added the reaction will shift to the left in order to remove the stress of the extra Cl2 and favor the production of more reactant.

2d. If PCl3 is removed, the reaction will shift to the right. When part of the equation is removed the reaction learns to adapt to the loss by trying to make more Pcl3 and counteract the effects of losing the PCl3.

3a. The reaction will shift to the right to produce more heat and counter the negative effects of losing the heat.

3b. It will shift to the left to get rid of the excess HCl being produced and form more reactant from the breakdown of the HCl.

3c. It would shift to the right in order to get rid of the excess form products from it.

3d. If pressure is decreased there will be no effect on the shift of the reaction because there is an even amount of moles of gas on each side.

4a. K=[N2O4(g0] / [NO2(g)]2

4b. (Below)

K=[N2O4(g)] / [NO2(g)]2

0.4 / 0.5(2)

0.4/0.25 = 1.6

Keq= 1.6

Gallium oxide, Ga.Oy, forms when gallium is combined with oxygen. A 1.25 g of Ga is allowed to react with excess oxygen and 1.68

mrs_skeptik [129]

Answer : The chemical formula of a compound is, $Ga_2O_3$

Solution : Given,

Mass of gallium = 1.25 g

Mass of gallium oxide = 1.68 g

Mass of oxygen = Mass of gallium oxide - Mass of gallium

Mass of oxygen = 1.68 - 1.25 = 0.43 g

Molar mass of Ga = 69.72 g/mole

Molar mass of O = 16 g/mole

Step 1 : convert given masses into moles.

Moles of Ga = $\frac{\text{ given mass of Ga}}{\text{ molar mass of Ga}}= \frac{1.25g}{69.72g/mole}=0.0179moles$

Moles of O = $\frac{\text{ given mass of O}}{\text{ molar mass of O}}= \frac{0.43g}{16g/mole}=0.027moles$

Step 2 : For the mole ratio, divide each value of moles by the smallest number of moles calculated.

For Ga = $\frac{0.0179}{0.0179}=1$

For O = $\frac{0.027}{0.0179}=1.5$

The ratio of Ga : O = 1 : 1.5

To make in whole number we multiple ratio by 2, we get:

The ratio of Ga : O = 2 : 3

The mole ratio of the element is represented by subscripts in empirical formula.

The Empirical formula = $Ga_2O_3$

The empirical formula weight = 2(69.72) + 3(16) = 187.44 gram/eq

Now we have to calculate the molecular formula of the compound.

Formula used :

$n=\frac{\text{Molecular formula}}{\text{Empirical formula weight}}$

$n=\frac{187.44}{187.44}=1$

Molecular formula = $(Ga_2O_3)_n=(Ga_2O_3)_1=Ga_2O_3$

Therefore, the chemical of the compound is, $Ga_2O_3$

The equilibrium constant "k" is used to determine the concentration of every product in a reversible reaction until equilibrium is reached. At equilibrium, the value of k is equal to 1.

When the value of k is less than 1, this means that the concentration of the reactants is more than the concentration of the products. To reach equilibrium again, the reaction will shift to the left forming more products to compensate for the concentration.

Based on this, there are only two choices which are:
<span>The concentration of one or more of the products is small.
</span><span>The reaction will not proceed very far to the right.

The other two are incorrect as:
The concentration of the reactants is more and not less
The reaction will generally form more products than reactants.</span>
