How many grams of CO2 are produced when 100 g C4H10 undergoes combustion with 200 g O2?
Use the following molar masses: C4H10=58g/mol, O2=32 g/mol and CO2=44g/mol.
Compare the moles of product formed from each reactant.

Postmodernism rejects any suggestion of absolute truth. What do you understand about the above statement?
Q about multiple dilutions - I have 9L of old motor oil; I replace 7L with new oil and mix. Then I replace 4.5L with new oil again. What is the final dilution of old oil remaining in the final 9L?
Which assessment model is best when comparing a learners knowledge with that of other learner in the same grade
Define the relative refractive index difference for an optical fiber and show how it
May be related to the numerical aperture. A step index fiber with a large core diameter compared with the wavelength of the transmitted light has an acceptance angle in air of 22° and a relative refractive index difference of 3%. Estimate the numerical aperture and the critical angle at the core–cladding interface for the fiber.
Can professional learning communities improve financial accountability and governance in schools? if yes state how and if no also state why and how
3. Measurements show that 500 muon fall on the top of Mt. Washington altitude 2000m. Muons travel at 99% the speed of light or 0.99 x 3.0 x 108 m/s.
a. Calculate the time in microseconds it would take muon to travel from the top of mt. Washington to its base.
b. Use your calculation and the muon clock graph to find how many muons should reach the bottom of Mt. Washington.
4. Experiments show that the actual number of muons that reach the base of Mt. Washington is 400.
a. According to your muon clock graph, how much time has elapsed if 400 muons reach the base of Mt. Washington?
b. By what factor do the times you found differ?
c. Suggest an explanation for this difference.
2. The half-life of muons provides you with a muon clock. Plot a graph of the number of muons versus time. Use 500 muons as the size of the sample. This graph will become your clock.
a. If 125 muons remain, how much time has elapsed?
b. If 31 muons remain, how much time has elapsed?
c. If 300 muons remain, how much time has elapsed?
d. If 400 muons remain, how much time has elapsed?
