The equivalence ratio of a combustion process is often determined by extracting a sample of the exhaust gas and measuring the concentrations of major species. in a combustion experiment using isooctane (c3h18), continuous gas analyzers monitor the exhaust gas and measure a co2 concentration of 6 percent by volume and a co concentration of 1 percent by volume. the sample gas is not dried before the measurements are made. a. what is the equivalence ratio associated with this combustion process? assume the process is overall lean. b. if an o2 analyzer was monitoring the exhaust gas, what would it be reading?

In the reaction between a crushed antacid tablet and vinegar what gas is emitted

Nebulae are enormous clouds in outer space. they are made mostly of hydrogen gas, helium gas, and dust. some nebulae glow brightly, while others do not. the stars that people see are huge, bright balls of glowing gas. they are made mostly of hydrogen and helium. which statement correctly describes other ways in which nebulae and stars are different? a. stars can form inside a nebula but a nebula can never be produced by any star. b. a star always has a higher density than a nebula. c. stars can never form inside a nebula but a nebula can be produced by any star. d. a nebula always has a higher density than a star.
