Are the charges in Li2O balanced yes o No?

motikmotik

Answer: For example, the Li 2 O content of the principal lithium mineral spodumene (LiAlSi 2 O 6) is 8.03%. Burning lithium metal produces lithium oxide. Lithium oxide is produced by the thermal decomposition of lithium peroxide at 300-400°C.

An earthquake causes a one 100 mile square area to be fractured into four different geographical areas. Two of the areas have a

Aloiza [94]

If it is a multiple answer question, then "The areas with the rivers will have the most plants" and " The areas with ponds will have more animals" would be your best answers. If it is a single answer question, then it would be best to go with the answer with 'The areas with the rivers will have more plant life",. The reason being, is that when there is a lot of water flow, there is more plant life around.

If an equal number of moles of reactants are used, do the following equilibrium mixtures contain primarily reactants or products

puteri [66]

Answer:

For a: The equilibrium mixture contains primarily reactants.

For b: The equilibrium mixture contains primarily products.

Explanation:

There are 3 conditions:

When $K_{eq}>1$ ; the reaction is product favored.
When $K_{eq}$ ; the reaction is reactant favored.
When $K_{e}=1$ ; the reaction is in equilibrium.

For the given chemical reactions:

For a:

The chemical equation follows:

$HCN(aq.)+H_2O(l)\rightleftharpoons CN^-(aq.)+H_3O^+(aq.);K_{eq}=6.2\times 10^{-10}$

The expression of $K_{eq}$ for above reaction follows:

$K_{eq}=\frac{[CN^-][H_3O^+]}{[HCN][H_2O]}=6.2\times 10^{-10}$

As, $K_{eq}$ , the reaction will be favored on the reactant side.

Hence, the equilibrium mixture contains primarily reactants.

For b:

The chemical equation follows:

$H_2(g)+Cl_2(g)\rightleftharpoons 2HCl(g);K_{eq}=2.51\times 10^{4}$

The expression of $K_{eq}$ for above reaction follows:

$K_{eq}=\frac{[HCl]^2}{[H_2][Cl_2]}=2.51\times 10^{4}$

As, $K_{eq}>1$ , the reaction will be favored on the product side.

Hence, the equilibrium mixture contains primarily products.

3. Sulfur dioxide (SO2) can be reduced by hydrogen disulfide (H2S), producing sulfur in its elemental form and water (H2O). Usin

Dafna1 [17]

The reaction between h2s and so2 results to h20 and elemental sulfur. The final reaction is SO2 +2H2S = 3S+ 2H2O. Using Hess law, the first equation is reversed and multiplied by 2, the second and the third equation remains the same. Calculating the overall enthalpy, the answer is 52.2 kJ.
