What is the heat capacity of an empty glass mug weighing 300.0 g, and what quantity of heat is required to heat it from 25 oC to 75 oC?
A buffer is made by mixing HCN and KCN to give a solution whose pH is 9.49. If the KCN molarity is 0.20 M, what is the molarity of the HCN?
Apply the steady state approximation to determine expressions for the rate of production of methane, CH4, and of ethane, C2H6.
Do all chemical compounds undergo each type of chemical reaction,i.e. synthesis, decomposition, metathesis-precipitation, metathesis-neutralization, redox-single displacement, redox-combustion and can this information be useful to a criminal inves..
Analysis of water in a sediment sample at equilibrium at ph 7.00 showed [so42-] = 2.00 x 10^-5 m and a partial pressure of h2s of 0.100 atm. show with appropriate calculations if methane, ch4, would be expected in the sediment.
