When is it okay to use Q = mcΔT Q = m c Δ T, is the equation only for calorimetry questions? When a question talks about heat how do I know if i'm measuring ΔH Δ H or Q?
Confusion on when to use mass of entire solution when …
2020年5月1日 · I am confused as to when exactly I should use the mass of the entire solution instead of the mass of the reactants in my Q = mc∆T and ∆H = ±Q/n calculations. Ideally, you always take the mass of the entire solution, and the heat capacity of the product mixture.

2007年6月30日 · I'm getting confused about what to use for the "M" term in q = MCAT For example: 20 g of of NaCl is poured into a coffee cup calorimeter containing 250ml of water. If the temp. inside drops by 1 degree Celcius by the time the …
q=MCAT | Student Doctor Network
2013年7月5日 · Hey guys I had a few questions about this equation. Does the q stand for the change in energy that must be provided (or removed) to change the temp of a substance? How would you conceptually tackle a problem that involves combining a hot substance with a cool that come together to an equilibrium...
q = mct - The Student Room
More accurately : \Delta Q = mc\Delta T ΔQ = mcΔT \Delta Q ΔQ has units of joules .The base unit of mass is the kilogram - 1 gram is 10^-3 kg and you need to stick to this. Units of \Delta T ΔT would be kelvins obviously. To get a consistent equation where the units on both sides must match up you would need c to have units of Jkg^ {-1}K^ {-1} J kg−1K −1 - …
Q on retaking MCAT after submitting AMCAS - Student Doctor …
2008年5月17日 · If you submit your app with your current MCAT scores, but then later that year decide to retake the MCAT, how does that work? Will the schools still accept the new scores if you submit them or are they exempt since you didn't indicate on the application that you planned to take the MCAT at a...

Heat of _____: Q=mcT versus Q=mH | Student Doctor Network
2011年6月15日 · Okay so I understand that the "m" in Q=mc (delta)T is mass, but isn't the m in Q = m (delta)H , moles instead of mass? I swear that I saw Chad use moles in when calculating heat of fusion, melting, etc. However, when I tried to solve a problem in kaplan they said it was mass instead of moles....
