Concept explainers
The correct option from the given set of options.
Answer to Problem 1MC
The correct option is “c. it combines with oxygen”.
Explanation of Solution
Combustion is burning of anything. This is a process which takes place in presence of oxygen. Oxygen is not a combustible gas but it is a supporter of combustion. When any substance or anything burns, it combines with oxygen to give oxides. Combustion is a rapid oxidation.
Conclusion:
Therefore from the above explanation, we can find that option c will be the best choice among the given options.
When something burns, it combines with oxygen and not with phlogiston (meaning flame). Hence, option a is an incorrect one.
When something burns, it does not means that surely it must produce flames. Hence, option b is an incorrect one.
When something burns, oxygen is consumed and not given out. Hence, option d is an incorrect one.

- 11. Blood Alcohol Content This question is about elimination of al- cohol from the blood. The elimination of ethanol from the blood is generally believed to have zeroth order kinetics, meaning that the rate of elimination is a constant, independent of the concen- tration. (a) Explain why it follows if no alcohol is being drunk, the blood alcohol concentration is described by the differential equation: dc -ko , c(0) = co dt where ko and co are both constants, which vary from person to person and depend on how much alcohol the patient has consumed. (b) Verify that a solution to this equation is c(t) = co – kot.arrow_forwardWhat is absorbed during bond breaking but liberated during bond formation?arrow_forwardYou overhear someone comment that a lot of cat cracking takes place in oil refineries.
