Problem- You obtain the following six measurements for the mass of water delivered by a special calibrated volumetric pipette: 1.180 g, 1.185 g, 1.181 g, 1.173 g, 1.182 g, and 1.181 g. determine the mean and confidence interval of these measurements at a confidence level of 95%.
My foremost issue is that I think I have to have a balanced reaction in order to do the calculations.
A rate constant obeys the Arrehnius equation, the factor A being 2.2 * 10^13 s-1 and the activation energy being 150 kj mol -1. What is the rate constant at 227 C, in s-1
Use MO theory to predict the net bond order after N2 interacts with a photon that results in the promotion of an electron from bonding to an antibonding orbital
a compound contains 10.13 c and 89.87 cl by mass. determine both the empirical formula and the molecular formula of the
the atomic mass of element x is 33.42 amu. a 21.83-g sample of x combines with 80.32 g of another element y to form a
You titrate 25.0 mL of 0.110 M NH3 (Kb = 1.76 x 10-5) with 0.100 M HCl. What volume of HCl is required to reach the equivalence point and what is the pH at the equivalence point
Norborneol synthesis in this manner is stereoselective. So, there are two possible products one endo and one exo. Only one will form, but why aren't there actually four possible products since the alcohol can form on either carbon in the alkene?
A hypothetical weak acid, HA, ws combined wih NaOH in he following proporions: .2 mol of HA, .08 ml of NaOH. The mixture was diluted o a total volume of 1.0 L and the pH measured.
The mysterious peptide X is a nonapeptide that cannot be sequenced by Edman degradation. However, it is susceptible to cleavage by proteases, and the resulting peptide fragments can be sequenced.
A compound is composed of elements C, H, and N. A 11.550-mg sample of the unknown compound was combusted, producing 31.332 mg of CO2 and 8.983 mg of H2O. What is the empirical formula for this compound
An aqueous solution of trichloroacetic acid, that is 2.00 percent by weight trichloroacetic acid, has a density of 1.0083 g/mL. A student determines that the freezing point of this solution is -0.382 oC.
A further, more detailed, analysis shows the compound to be 40.3% B , 52.2% N, and 7.5 H " all mass percent", what is the molecular formula of the substance
