CaC2 + 2H2O --> C2H2 + Ca(OH)2. Using this equation, determine how many moles of CaC2 are needed to react completely with 49 g H2O?
what would be the atmospheric pressure of MTBE in Pa If this sample were at equilibrium with atmospheric MTBE? KH = 1.7 M/atm.
The reaction CH3CH2NO2 + OH- → H2O + CH3CHNO2- obeys the rate law d[A]/dt = -k[A][OH-], where A denotes CH3CH2NO2. It takes 0.5 min for one percent of the A to react at 25°C.
An element has two isotopes with masses of 62.9396 u and 64.9278 u,and 30.83% of the atoms are the heavier isotope. Calculate the atomic mass of this element and give its name and symbol.
Assume that 0.406 mol Carbon (g) is placed in a cylinder that is expanding. The barometric pressure on the outside of the cylinder is constant at 1.00 atm and the temperature is 300.0 K.
