Use ΔG=ΔH-TΔS to calculate the standard free energy change, ΔG, at 25oC for the following reaction: CaCO3(s)-->CO2(g) + CaO(s)
The reaction takes place in a bomb calorimeter where 4.50g of glucose are burned. What is the heat capacity of the bomb if the temp. of the water in the bomb increases from 22.75 degrees Celsius to 25.32 degrees Celsius? I used qrxn = -Ccal*change..
a 45-g piece of ice at 0 degrees C is added to a sample of water at 9 degrees C. All of the ice melts and the temperature of the water decreases to 0 degrees C. How many gram sof water were in the sample?
How many valence electrons does one molecule of aspartame have? What are the bond angle measurements of aspartame?
At 0.0oC, if the volume of air is 3.4 mL and the pressure of the atmosphere that day is 695 mmHg, what is the number of moles of air?
the freezing point (5.5 C) and boiling point (80.1 C) of benzene and the temperature difference between these points was divided into 50 units (called X), what would be the freezing and boiling points of water in X
The reaction takes place in a bomb calorimeter where 4.50g of glucose are burned. What is the heat capacity of the bomb if the temp. of the water in the bomb increases from 22.75 degrees Celsius to 25.32 degrees Celsius?
