As a result of a chemical spill, benzene is evaporating at the rate of 1 gram per minute into a room that is 6 m * 6 m * 3 m in size and ahs a ventilation rate of 10m^3/min
a. Compute the steady-state concentration of benzene in the room. (I have already done this)
b. Assuming the air in the room is initially free of benzene, compute the time necessary for benzene to reach 95% of the steady-state concentration.
A 100 ml sample of rainwater is neutralized by 22.4 ml of .0122 M NaOH. Assuming that the acid present in sulfurous acid, which resulted from the reaction of SO2 with water, what is the molarity of acid in the rainwater
For the reaction 2HI(g) H2(g) + I2(g), Kc = 0.290 at 400 K. If the initial concentrations of HI, H2, and I2 are all 1.50 × 10-3 M at 400 K, which one of the following statements is correct
Ionization energy is the energy needed to eject an electron from an atom. Compute the ionization energy of a hydrogen atom in its first excited state (n = 2).
A piece of metal weighing 10.0g is raised in tempreture from 25 C to 76.5C. it is found that it absorbed 47.6 calories of heat in the process.
The following minerals contain silver. Rank the minerals in order of percent silver from least to greatest: miersite, AgI; hessite, Ag2Te; empressite, AgTe; and cerargyite, AgCl.
Caffeine is made up of 49.5% C, 5.2% H, 16.5%O, and 28.9% N. A solution made up of 8.25g of caffeine and 100.0 of benzene (d=0.887g/ml) freezes at 3.03C. Pure benzene (kf=5.10 degrees C/m) freezes at 5.50C.
Calculate the pH for an aqueous solution of acetic acid that contains 3.15 × 10-3 M hydronium ion.
