Answer:A fundamental difference is that physics is more focused to finding the universal laws of general processes, whereas chemistry focuses more on details and specific phenomena, such as what is the boiling point of this substance and why.

Explanation: hope it help

There is a lot more physics in a chem lab than there is in a physics lab. Physical properties are also looked at in chem lab experiments, but they aren't the only things that are looked at. To give you an example, it has a melting point and boiling point. It also has a denseness, color, odor, and transparency The electron, a particle that is so important to the study of chemistry, is a physical thing. Its mass, charge, and energy are all physical things. Voltmeters, ammeters, magnetic spinners, mass-spectroscopes, Geiger counters, and cloud chambers are just some of the physics instruments that are important in a chemistry lab. The list is long. In any chemistry lab, there is a centrifuge. It's a great tool that uses four physics principles to do its job. Pipettes and burettes are high-quality instruments that were made with thermal expansion constants in mind. This word is often used to talk about the barometer: There aren't any barometers in this lab, but do you think it can still be good?

It's now time to write down all of the chemistry principles that are found in the tools, properties, and applications of a physics lab. I'll start it for you now.

In order to build voltaic cells, you need iron filings and electrolytes.
Radioactive decay, alpha, beta, and gamma emission, and atomic transformation all happen.

Which two parts of sedimentary rock formation include the breakdown and carrying away of existing rock?
Rzqust [24]

erosion and weathering.

erosion as in breaking it down, weathering is also a cause of erosion, but in the case of rain, it would carry away the remaining sediments.

A galvanic cell at a temperature of 25.0°C is powered by the following redox reaction:
Vlada [557]

<u>Answer:</u> The cell voltage of the given chemical reaction is 2.74 V

<u>Explanation:</u>

For the given chemical reaction:

Sn^{2+}(aq.)+Ba(s)\rightarrow Ba^{2+}(aq.)+Sn(s)

Here, gold is getting reduced because it is gaining electrons and nickel is getting oxidized because it is loosing electrons.

<u>Oxidation half reaction:</u>  Ba(s)\rightarrow Ba^{2+}(aq.)+2e^-;E^o_{Ba^{2+}/Ba}=-2.90V

<u>Reduction half reaction:</u>  Sn^{2+}(aq.)+2e^-\rightarrow Sn(s);E^o_{Sn^{2+}/Sn}=-0.14V

Substance getting oxidized always act as anode and the one getting reduced always act as cathode.

To calculate the E^o_{cell} of the reaction, we use the equation:

E^o_{cell}=E^o_{cathode}-E^o_{anode}

E^o_{cell}=-0.14-(-2.90)=2.76V

To calculate the EMF of the cell, we use the Nernst equation, which is:

E_{cell}=E^o_{cell}-\frac{0.059}{n}\log \frac{[Sn^{2+}]}{[Ba^{2+}]}

where,

E_{cell} = electrode potential of the cell = ?V

E^o_{cell} = standard electrode potential of the cell = +2.76 V

n = number of electrons exchanged = 2

[Ba^{2+}]=5.15M

[Sn^{2+}]=1.59M

Putting values in above equation, we get:

E_{cell}=2.76-\frac{0.059}{2}\times \log(\frac{1.59}{5.15})\\\\E_{cell}=2.74V

Hence, the cell voltage of the given chemical reaction is 2.74 V
