A .500 g sample of glucose (C6H12O6, MW=180g/mol) is burned in a bomb calorimeter. The temperature of the calorimeter increases from 19.7C to 20.6C. If under constant volme conditions the heat of combustion of glucose is -2805 kj/mol, calculate the total heat capacity of calorimeter.
the atmosphere and since CO2 dissolved in water causes it to be slightly acidic, will the use of deionized water that has not been previously boiled cause the mass
Starting with standard reduction potentials calculate the values of e cell and delta g of the following reactions:
Predict the probability P9v) that a molecule will have a given total velocity of more specifically P(v)dv is the probability that a molecule will have a velocity btwn v and v+dv.
Assume the total heat capacity of the air C air=30 J/K. Describe what's the likely ice will ne after the system reaches equilibrium. b) Estimate theliekly final temperature after reaching equilibrium
The half-life for the radioactive decay of [U]-238 is 4.5 billion years and is independent of initial concentration.
Draw the first mechanistic step( one intermolecular arrow and any subsequent intramolecular arrows needed to finish the mechanistic step) between caffeine and hydrochloric acid.
Calculate the concentration of ethanol in wine in terms of mass percent and molality. mass percent? answer in % molality? answer in mol/kg
