4. Suppose a student performs this experiment and obtains a molecular weight of 65 g/mol for t-butyl alcohol. Give valid sources of error for what could have caused the molecular weight to be lower than expected.

Who is better, messi or cristiano, i need this for a chemistry class. asap

Which atom or ion is the largest? a. k b. k+ c. ca d. ca2+ e. li

For the reaction, 4 a(g) + 3 b(g) => 2 c(g), the following data were obtained at constant temperature. experiment initial[a],mol/l initial [b],mol/l initial rate,m/min 1 0.200 0.150 5.00 2 0.400 0.150 10.0 3 0.200 0.300 10.0 4 0.400 0.300 20.0 which of the following is the correct rate law for the reaction? 1. rate = k[a]2[b]2 2. rate = k[a][b] 3. rate = k[a]2[b] 4. rate = k[a][b]2
