PLEASE HELP?? Describe how the periodic table differentiates between metals and nonmetals.

1 answer:

4 0

Metals are the majority of the periodic table. Also, they are on the left side of the periodic table. The no metals are on the right side of periodic table.
Hope I Helped!

Answer:

4x^3

Explanation:

Solubility product constant is usually written as (Ksp). It is defined for equilibrium between a solids and its respective ions in a solution. Its value indicates the degree to which a compound dissociates into ions in water. The higher the solubility product constant, the more soluble the compound.

Solubility of a solute is defined as the maximum amount of solute that can be dissolved in a solvent at equilibrium while the solubility product constant (Ksp) describes the equilibrium between a solid and its constituent ions in a solution.

For AB2(s)< -------> A(aq) + 2B(aq). But solubility of AB2= x

Ksp= x × (2x)^2

Ksp= 4x^3

Convert 34.59cm3 to cubic inches (in3) given that 1 inch = 2.54cm

JulsSmile [24]

Answer:

$2.111in^3$

Explanation:

Hello,

In this case, we are able to perform this unit conversion by cubing the relationship between inches and centimetres as shown below:

$=34.59cm^3*(\frac{1in}{2.54cm})^3 \\\\=34.59cm^3*(\frac{1in^3}{16.39cm^3} )\\\\=2.111in^3$

Best regards.

1. (a) Write the two electrochemical half reactions for ethanol (C2H5OH) direct electrochemical conversion in a fuel cell with a

Natalka [10]

Answer:

(a) Two electrochemical half reactions for ethanol $(C_{2}H_{5}OH)$ is written below

$C_{2}H_{5} + 60$ ⇒ $2CO_{2} + 3H_{2}O + 12e^{-} (anode)$

$3O_{2} + 12e^{-}$ ⇒ $60^{=}$ $(Cathode)$

(b) The direct oxidation of the fuel will occur in a solid oxide fuel cell but we have to compete with other sets of chemical electrochemical reaction such as water-gas-shift reaction

$CO + H_{2}O$ ⇆ $CO_{2} + H_{2}(WGSR)$

(c) The electrochemical half reaction that could convert ethanol directly into a fuel cell that conducts hydrogen ions is shown below

$C_{2}H_{5}OH + 3H_{2}O$ ⇒ $2CO_{2} + 12H^{+} + 12e^{-} (anode)$

$3O_{2} + 12H^{+} + 12e^{-} - 6H_{2}O (Cathode)$

$C_{2} H_{5} OH + 3O_{2}$ ⇒ $3H_{2}O + 2CO_{2}$

(d) The half reactions that would be required are shown below

$C_{2}H_{5} OH + 12OH^{-}$ ⇒ $CO_{2} + 9H_{2}O + 12e^{-} (anode)$

$3O_{2} + 6H_{2}O + 12e^{-}$ ⇒ $12OH^{-} (Cathode)$

$C_{2}H_{5}OH + 3O_{2}$ ⇒ $3H_{2}O + 2CO_{2}$

How are the reactants represented in the chemical equation for photosynthesis? 6co2 o2 6co2 6h2o c6h12o6 6o2 c6h12o6 6h2o

Vika [28.1K]

The reactants of photosynthesis are represented by $6CO_2$ and $6H_2O$ .

<h3>Photosynthesis</h3>

It is a reaction through which green plants make use of inorganic products such as water and carbon dioxide in the presence of solar radiation to make sugar. Oxygen is liberated as a by-product.

The equation of the reaction is represented by:

$6CO_2 + 6H_2O --- > C_6H_{12}O_6 + 6O_2$

Thus, the reactants are represented by $6CO_2$ and $6H_2O$ respectively.
