Answer:
E° = -0.133 V
Explanation:
In the reaction:
X(s) + Y⁺(aq) → X⁺(aq) + Y(s)
<em>1 electron is transferred from X to Y</em>
Now, using Nernst equation:
E° = RT / nF ln K
<em>Where R is gas constant (8.314 J/molK), T is absolute temperature (Usually 298.15K), n are transferred electrons (1, for the reaction), F is faraday constant (96485C/mol) and K is equilibrium constant (5.59x10⁻³)</em>
Replacing:
E° = 8.314 J/molK*298.15K / 96485C/mol*1 ln 5.59x10⁻³
<em>E° = -0.133 V</em>
Yes...yes it does describe an exothermic reaction
Answer:
C. making models
Explanation:
Making models facilitates constructing depictions of complex objects or practices that enable students to practice and understand how things work which can not be observed and measured directly. Model making needs abstract thinking about the tools and material used, spatial thinking, and well-organized idea of the project to create complex objects.
Answer:
a. release of heat flames or light - Physical Change
b. formation of precipitate - Chemical Change
c. change in substances size - Physical Change
d. change in an objects shape - Physical Change
e. change in an objects phase of matter - Physical Change
f. releasing gases/bubbles - Chemical Change
Explanation:
These are all either changes in physicality or in chemical structures; hope I helped either way!
Answer:
I think its to indicated a mood change..but i do wanna say to indicate an unstated thought.Hope either one is right
