When a small piece of sodium metal is dropped into a beaker of water, hydrogen gas (H2) and a solution of sodium hydroxide (NaOH

) are products. The solution becomes warm.

Answer:

The reaction is exothermic as the solution becomes warm.

Explanation:

Hello there!

In this case according to the described reaction between sodium metal and water, we can write up the chemical equation whereas the products turn out to be sodium hydroxide and hydrogen gas:

2Na+2H_2O\rightarrow 2NaOH+H_2

Moreover, these reactions are known to be highly exothermic, for that reason the solution becomes warm as the reaction releases heat as it goes to completion.

Best regards!

What is e° cell for the reaction of nickel(ii) ions with cadmium metal at 25°c? ( r = 8. 314 j/k • mol, f = 96,500 c • mol –1) n
Alexus [3.1K]

At anode,

Cd----->  + 2

At cathode,

 + 2e -----> Ni

Overall reaction,

+ Cd(s) ------> + Ni                          K=1.17

(aq)                          (aq)      (s)

By nernst equation,

E=  -  Log K

Where,

          F=96500c/mol

         M=2

          T=298K

         E=Zero at equilibrium

R=8.314 J

0=  - Log(1.17)

= 0.150v

what is nernst equation?

The Nernst equation is a chemical thermodynamical relationship used in electrochemistry that enables the determination of a reaction's reduction potential (half-cell or full-cell reaction) from the standard electrode potential, absolute temperature, the number of electrons involved in the oxydo-reduction reaction, and activities (often approximated by concentrations) of the chemical species undergoing reduction and oxidation, respectively. It was given the equation's original name in honor of the German physical scientist Walther Nernst.

The link between cell potential, standard potential, and the behaviors of electrically active (electroactive) species is described by the Nernst equation. It links the standard cell potential to the effective concentrations (activities) of the reaction's constituent parts.

Which would have a higher pH, a 0.1 M solution of a strong acid, or a weak acid? Why?
DerKrebs [107]

Answer:

0.1 M weak acid

Explanation:

The term pH simply means power of hydrogen which is basically a log (the exponent to base 10 of the concentration) of the concentration of the hydrogen ions.

Weak acids have a higher pH since their hydrogen concentration is lower than that of strong acids.

What is a process by which long-term carbon is released into the atmosphere
LekaFEV [45]

Answer:

The carbon cycle

Or

Carbon moves from living things to the atmosphere. Each time you exhale, you are releasing carbon dioxide gas (CO2) into the atmosphere. Animals and plants get rid of carbon dioxide gas through a process called respiration. Carbon moves from fossil fuels to the atmosphere when fuels are burned.
