Why does finding a straight line relationship help you to understand the nature of the relationship between transmittance and concentration?
Consider the following thermochemical equation: CH4(g) + I2(g) --> CH3I(g) + HI(g) Enthalpy Value = +23 kJ
A solution was prepared by mixing 70ml of 4.00 mol/L HCl and 30.0 mL of 8.00 mol/L HNO3. Water was then added until the final volume was 500ml. What is the [H+] and what is the pH ?
Looking at the nickel complexes as an example, it is found that those formed with ammonia give the complex [Ni(NH3)6]^2+ and when formed with ethylenediamine the complex [Ni(en)3)^2+ is the result.
Calculate the change in chemical potential of an ideal gas when its pressure is increased isothermally from 1.8 atm to 29.5 atm at 40 C.
If a 55 laboratory mouse is exposed to 21.5 rad of radiation, how much energy was absorbed by the mouse's body
what is the minimum amount of 6.0 M H2SO4 neccessary to produce 23.5 g of H2(g) according to the following reaction? 2Al(s) +3H2SO4(aq) --> Al2(SO4)3(aq) + 3H2(g)

Describe the impact of time of exposure on the amount of radiation you receive. If you are exposed for three times as long do you feel 1/3 the amount of radiation, three times the amount of radiation
If you open the valve on the tank and release the helium into a room with a volume of 10,000 liters, what will happen to the "space" between the helium atoms? Clearly explain
aqueous solution in the upper intestinal tract where the pH is 5.83. Calculate the percent of sulfisomidine in the neutral form in the solution of the intestinal tract.
Radioactive isotopes often occur together in mixtures. Suppose a 190 sample contains , with a half-life of 12 days, and , with a half-life of 4.5 days. If there are initially twice as many calcium atoms as there are barium atoms, what will be the ..
