A natural gas mixture is burned in a furnace at a power-generating station at a rate of 13.0 mol per minute. (a) If the fuel consists of 9.3 mole CH4, 3.1 mole C2H6, 0.40 mol C3H8, and 0.20 mole C4H10, what mass of CO2 (g) is produced per minute? (b) How much heat is released per minute
The quantity of acetylene (HC+CH) in a gas mixture was measured by mass spectrometry, in which the signal for mass number 26 is proportional to the volume percent of acetylene. Gas Signal (mV) Blank containing no acetylene 0.2
Write the equation for the esterification reaction between ethanol and acetic acid (ethanoic acid), Write the equation for the esterification reaction between ethanol and acetic anhydride(ethanoic acid anhydride)
Suppose that the microwave radiation has a wavelength of 12.4cm . How many photons are required to heat 295mL of coffee from 25.0 C to 62.0 C ? Assume that the coffee has the same density, 0.997 g/mL , and specific heat capacity, 4.184 J(gxK) , as..
You will start with 500 mg of one of isoamyl acloho to make isoamyl acetate. While the alcohols are liquids, we will measure them by mass directly on the balance, not by volume (i.e. the density of the alcohol will not be used; pretend the alcohol..
What volume of 3.00 M NaOH must you add to the acetic acid to achieve a buffer with a pH of 5.00 at a final volume of 500 mL? (Ignore activity coefficients.)
Small air bubbles in the salt bridge may not be a problem. How can the presence of air bubbles in the salt bridge alter the effectiveness of this salt bridge
What are the reactions happen at the negative limit. Why is the negative limit in a given medium always more positive for platinum than it is for glassy carbon
In the borohydride reduction of camphor, the two end products were borneol and isoborneol.
Consider the the list below for the formation of esters of acetic acid using different alcohols. What does it tell you about the relative ease of preparation of esters from different types of alcohols
A sample of the Dead Sea Scrolls gives a ^14C decay rate of 731 disintergrations/h. A modern sample gives 920 disintergrations/h. Estimate the age of the Scrolls from these data.
What fraction of the spherical atomic volume is occupied by the nucleus? What fraction of this atom's mass is contributed by its nucleus?
If glass beads in the lab were replaced by a material with less surface area, will liquid seperation be better or worse. Why. Why should the recieveing flask be submersed under an ice bath when collecting isopropanol or acetone
