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.
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. ???????
Nomenclature and common formula. When part of a salt, the formula of the acetate ion is written as CH3CO2−, C2H3O2−, or CH3COO−. Chemists abbreviate acetate as OAc− or, less commonly, AcO−. Thus, HOAc is the abbreviation for acetic acid, NaOAc for sodium acetate, and EtOAc for ethyl acetate.
If we look at the reaction profile pictured in the question, we can easily identify A as the enthalpy of the reaction. The enthalpy of reaction (ΔHrxn) is usually defined as the difference between the total enthalpy (heat content) of the products of a reaction and the total enthalpy (heat content) of the reactants in that reaction.
Looking at the figure, we can see that the enthalpy of products is greater than the enthalpy of reactants, hence ∆Hrxn is positive as stated in the answer above.
The dew point refers to the temperature at which the amount of water vapor present in the air is so high that the relative humidity becomes 100%, and with the increasing rate of cooling, the condensation process takes place and dew is formed.
So for dew point to occur, the air temperature must reach a condition where the air is fully saturated or the relative humidity is 100%.
In (NH4)2C2O4 there are four moles of Hydrogen in the compound (NH4), but there two molecules of (NH4) in this compound. That's what the 2 in (NH4)2 means, so multiply 4 x 2 = 8.
