If 1.0 volumes of 1.0 M solutions of sodium hydroxide and lead (II) nitrate are mized how many moles of product are produced?
For the fractional distillation, a mixture hexane (b.p.=69) and toluene (b.p.=110.6) is used. a. Sketch a temperature versus volume diagram. Would it be a negative slope because the more volume of a substance you gave the higher bp
If an electric car is capable of going 220. km on a single charge, how many charges will it need to travel from Boston, Massachusetts to Miami, Florida, a distance of 1486 mi, assuming that the trip begins with a full charge?
Calculate the mass of emitted into the atmosphere upon accelerating the from 0.0 to 67.0 . Assume that the required energy comes from the combustion of octane with efficiency.
Identify the total number of ethyl groups. (b) Independently of (a), identify the total number of methyl groups. Note that these groups are not necessarily confined to those specifically mentioned in the name.
will strontium sulfate form a precipitate at 25 degrees celcius when 345mL of a solution that is .0100M in Sr+2(aq) is added to 75mL of a .175M SrSO4
The density of germanium is 5.325 g/cm3. If you made a 5.3-nm diameter quantum dot of germanium, how many Ge atoms would it contain? Assume the dot is spherical.
Which process would have a entropy greater than 0. a. n2(g)+3H2(g) = 2nh3(g) b. ch4(g) + h2o(g) = co(g) + 3h2(g) I believe it's b. because the molar masses of the products are similar so I would say that b. has more complex species so it's entropy..
why is anhydrous sodium sulfate added to the organic solution remaining after the extractions with 6 M HCL and 6 M NaOH

write Lewis structure for Oxygen difluoride, OF2. How many lone pairs are one the oxygen atom
Both (E)- and (Z)- 2-cholorobutenedioic acids dehydrochlorinate to give acetylene dicarboxylic acid. The Z acid reacts about 50 times faster than the E acid. Explain.
Some observations through an experiment shows that a gas sample of 115 mili litres has a mass of 0.170 grams at a pressure of 711mmHg and a temperature of 34 degree celsius. Determine the molar mass of the gas.
