Answer:

Explanation:

Compared to the process of extracting lithium from mineral deposits, the process of extracting lithium from evaporation ponds requires __less____ water, __less____ money, and ___less________ time.

Lithium extraction from salar brines are more economical to extract compared to extraction from their natural ore deposits. Salar brines occurs as liquid underground brine reservoirs. Once pumped to the surface in ponds, they are left to evaporate and the lithium is concentrated from them. Extraction from brines in ponds do not require water that much, less cost and if the evaporation rate is fast, a lot of time can be saved.

Extraction from mineral deposits require a lot of energy and time to achieve.

What is reduction potential?​
Shtirlitz [24]

Answer:

A reduction potential measures the tendency of a molecule to be reduced by taking up new electrons. ... Standard reduction potentials can be useful in determining the directionality of a reaction. The reduction potential of a given species can be considered to be the negative of the oxidation potential.

Using the data below, calculate the enthalpy for the combustion of C to CO C(s) + O2(g)--> CO2 (g) ΔH1 = -393.5 kJ CO(g) + 1/
natali 33 [55]

Answer:

ΔH = -110.5kJ

Explanation:

It is possible to obtain enthalpy of combustion of a particular reaction by the algebraic sum of similar reactions (Hess's law). Using:

1. C(s) + O₂(g) → CO₂(g) ΔH₁ = -393.5kJ

2. CO(g) + 1/2O₂(g) → CO₂(g) ΔH₂ = -283.0kJ

The sum of 1 -2 gives:

C(s) + <u>O₂(g)</u> + <u>CO₂(g)</u> → <u>CO₂(g)</u> + CO(g) + <u>1/2O₂(g)</u>

C(s) + 1/2O₂(g) → CO(g) ΔH = -393.5kJ - (-283.0kJ) =

<h3>ΔH = -110.5kJ</h3>

What is one disadvantage of wind and hydroelectric power?OA. Their supplies are limited and only last a few years in a singlocat
Goshia [24]

Answer:

C

Explanation:

Here, we want to select a disadvantage of the power sources

The two listed are examples of renewable power sources with no level of pollution

However, in the case of wind, a wind turbine is needed and could only work in places where the wind is prevalent enough throughout the year. Likewise, hydroelectric power, can only work where we have a flowing water source

Thus, there is a bane of geographic and climatic restrictions serving as a disadvantage

Give the net ionic equation for the reaction (if any) that occurs when aqueous solutions of Al(C2H3O2)3 and LiNO3 are mixed. Giv
RSB [31]

Answer: No reaction occurs

Explanation:.

Spectator ions are defined as the ions which does not get involved in a chemical equation or they are ions which are found on both the sides of the chemical reaction present in ionic form.

The given chemical equation is:

Al(C_2H_3O_2)_3(aq)+3LiNO_3(aq)\rightarrow Al(NO_3)_3(aq)+3LiC_2H_3O_2(s)

The complete ionic equation is;

Al^{3+}(aq)+3C_2H_3O_2^-(aq)+3Li^+(aq)+3NO_3^-(aq)\rightarrow Al^{3+}(aq)+3NO_3^-(aq)+3Li^+(aq)+3C_2H_3O_2^-(aq)

The ions which are present on both the sides of the equation are are not involved in net ionic equation.

Hence, there is no net reaction.
