A book is resting on a table. One end of the table is slowly raised until it makes an angle of 12.6 relative to the horizontal, at which point the book begins to slide down the table. What is the value of μs for this situation?
A beaker contains 115g of ethanol at 18.2 degrees C. Explain if the ethanol absorbs 1125J of heat without losing heat to the surroundings, explain what will be the final temperature of the ethanol? The specific heat of ethanol is 2.46J/g*degrees C..
Sugar (C6H12o6) combusts and releases 246.8 kJ what is the complete chemical reaction? What is the enthalpy of the reaction
What is the change in internal energy (in J) of a system that absorbs 0.535 kJ of heat from its surroundings and has 0.362 kcal of work done on it
During the dehydration reaction when acetaldehyde was reacted with KOH in ether, an intermediate was formed. What was this intermediate that was eventually converted to the final product?
Consider the chemical reaction 2NH3(g) N2(g) + 3H2(g). The equilibrium is to be established in a 1.0 L container at 1,000 K, where Kc = 4.0 ? 10-2. Initially, 1,220 moles of NH3(g) are present. Estimate the equilibrium concentration of N2(g).
This increases to 0.010 Msec^-1 at 90 degrees C. Calculate the activation energy for this reaction.
the rate constants of some reactions double with every 10 degree rise in temperature. assume that a reaction takes
