Hello Prof. Eman! Thank you for everything! In question #7 at 27:08 - why wouldn't you multiply by -9.8m/s2 when the acceleration is moving downwards, instead of +9.8m/s2? Also, if the static force was equal to the perpendicular force, does that mean it's the force necessary to move move the wagon forward?
@professoreman2289 Күн бұрын
It’s important to understand the point of the negative sign - it’s signals information on direction. You can include it but we already have that information in the diagram drawn and we’re just calculating the magnitude of the force in this problem.

The value of n represents the number of moles of electrons transferred and it is determined by the balanced overall redox reaction.

hi for the sloped increase in temp we use q=mcat and horizontal we use q=n x delta h. why didnt we use moles x delta h we used mass times delta h. i thought you have to convert to moles for the horizontal phase change

@nelsonjones443 4 күн бұрын
Not necessarily a time stamp, but the heating and cooling curve differs in gen chem compared to physics because in gen chem it uses moles for the phase change horizontally not the mass times enthalpy as physics ch uses. Question 5

at time 14.49, speaking upon two equations you refer to the first one as NCF, but isnt that equation representing conservative forces? and the second equation represents NCF?
@professoreman2289 5 күн бұрын
I see your confusion, let me elaborate on that for you. The first part refers to situations where no non-conservative forces, like friction, are acting. In this case, the total mechanical energy, which includes both kinetic and potential energy, remains constant because only conservative forces are present. The second part refers to situations where non-conservative forces are present. Here, the work done by these forces, like friction or air resistance, changes the system’s total energy.

For #1, in the beginning of the problem why don't we convert the celsius to kelvin by adding 273? i noticed in the textbook they changed it to kelvin but didn't add the 273.
@professoreman2289 6 күн бұрын
Hi! As mentioned in the lecture videos, when calculating ΔT (change in temperature), the result is the same whether you use Celsius or Kelvin. This is because the size of the degree is identical in both scales. So, to save time on exams, you can use either Celsius or Kelvin for ΔT-they will give you the same result.

For #15 I chose D.Water molecule because I thought it could also be interepreted as a neutralization reaction that forms a water and salt. Is this not the case? (since ammonia is a base and COOH and acid) or would it not occur since ammonia is a weak base? Thank you so much for your videos!!! You are literally me and my friend's saving grace as we study for the MCAT!! Please wish me, Danya, and Ria good luck as we test in the Spring!!! We love you!
@professoreman2289 6 күн бұрын
Hi Sophie! Great question! While ammonia (a weak base) and the carboxylic acid group (COOH) can interact, this reaction doesn’t proceed as a typical neutralization to form water and salt. Instead, it’s a condensation reaction where ammonia reacts with the carboxylic acid to form an amide, and water is released as a byproduct. This happens because ammonia acts as a nucleophile, attacking the carbonyl carbon of the acid. So, the final product is an amide, not water! Best of luck to you, Danya, and Ria on the MCAT! You’re going to crush it and I love you all!!!

For the 2nd example, why do we not flip the sign for the E red of Fe 2+, if the half reaction is flipped when we calculate the emf?
@professoreman2289 6 күн бұрын
When calculating the cell potential (E°cell), you do not flip the sign of the reduction potential for Fe³⁺/Fe²⁺ even if the half-reaction is written in reverse because standard reduction potentials (E°red) are always listed as reductions. The potential difference depends on the nature of the species and not the direction of the reaction. Instead of flipping the sign, the correct method is to simply subtract the anode (oxidation) potential from the cathode (reduction) potential. So, No need to manually change signs - the subtraction takes care of it. Hope that helps Noel! Let me know if you have anymore questions:)
