4 0

Answer:

The Celsius scale is in general use wherever metric units have become accepted, and it is used in scientific work everywhere. Kelvin temperature scale is the base unit of thermodynamic temperature measurement in the International System (SI) of measurement

(b) Which peak, the one at 365 nm or the one at 435 nm, results from the absorption of
GenaCL600 [577]

Answer:

365nm and Exothermic reaction

Explanation:

b) The Einstein Planck's equation states that

E = hf where E is the energy of a photon

                     h  is the Planck's constant

                     f  is the frequency

But Frequency f = c/λ  where c  is the speed of light

                                                  λ  is the wavelength

Therefore Energy E = hc/λ

From the above equation we see that the Energy of a photon is indirectly proportional to its wavelength

Hence as the wavelength increases from 365nm to 435nm, the energy of the photons decreases

Therefore, a photon will wavelength 365nm would have a higher energy than one will wavelength of 435nm.

c) From the diagram we observe the following:

At high temperatures,   HPR⁺ occurs at a higher concentration than at low temperatures.

At low temperatures, more of PR⁻ is formed than at high temperatures

The equation of the reaction is

HPR⁺ (aq) ⁺ ⇆ H⁺ + PR⁻(aq)      

Le Chartelier's principle states that when an external constraint such as a change in concentration, pressure or temperature is placed on a system in equilibrium, the system acts in such a way as to oppose the change.

Hence a decrease in temperature on the side of reactant, HPR would force the equilibrium to the side of the products, PR in other to accommodate the change

The forward reaction, which produces more of the product PR⁻ is exothermic because  the at low temperatures, the the forward reaction is favoured and equilibrium shifts to the right.

Draw the best lewis structure for h 2 ​ co 3 ​ and calculate the formal charge on carbon.
schepotkina [342]
The Lewis structure of Carbonic Acid (H₂CO₃) is given below. In structure it is shown that carbon has a double bond with one oxygen atom and two single bonds with hydroxyl groups.

Formal Charge;
                        Formal charge is caculated as,

Formal charge  =  # of valence e⁻ - [# of lone pair of e⁻ + 1/2 # of bonded e⁻]

Formal charge on Carbon;

Formal charge  =  4 - [ 0 + 8/2]

Formal charge  =  4 - [4]

Formal charge  =  Zero

Compared to the process of extracting lithium from mineral deposits, the process of extracting lithium from evaporation ponds re
Shtirlitz [24]

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.
