What are some changes that can be caused by sound energy? by electromagnetic energy?
Pavel [41]

Hearing loss due to sound energy damaging the nerve cells in the inner ear. Many animals behavior is influenced by sound energy. They learn to associate events with sounds, so they run when something crunches in the dry grass (might be a coyote), but won't be bothered by the sound of a waterfall. Mood is affected by sound energy. A wine glass can break with sound energy, if the frequency matches the resonant frequency of the wine glass and the amplitude is great enough (one Mythbusters show featured a professional singer who broke a wine glass with his voice without any amplification).

What is the name of this compound?<br><br> 2-butanone<br> 2-pentanone<br> 4-pentanone<br> 4-butanone
UkoKoshka [18]

Answer:

2-pentanone

Explanation:

The oxygen atom is attached to the 2nd carbon atom in the longest linear chain, thus the prefix 2. the longest continuous carbon chain has five carbon atoms giving it the prefix pent-. the chemical is a ketone thus the suffix none.

Why is the adhesive property of the pvc plastic important? 1 pt?
GrogVix [38]
 I believe this property is vital since the sticky nature allows the wells to coat easily with the desired antigen by simply adding a small amount of it and allowing it time to incubate. Adhesion is the tendency of dissimilar particles or surfaces to cling to one another ( cohesion refers to the tendency of similar or identical particles/surfaces to cling to one another).

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.
