Answer:
The air pressure at sea level is about 14.7 pounds per square inch (psi). For every foot above sea level, the air pressure drops about 0.0005263 psi. According to this information, at about what height above sea level is the air pressure 13.2 psi?
Answer:

Explanation:
Hello,
In this case, the combustion of octane is chemically expressed by:

In such a way, due to the 25/2:8 molar ratio between oxygen and carbon dioxide, we can compute the yielded grams of carbon dioxide (molar mass 44 g/mol) as shown below:

Best regards.
Hawking was the first to set out a theory of cosmology explained by a union of the general theory of relativity and quantum mechanics.
Answer: Molar mass of CO2 is 44 gram/mol. So,the mass of 1 mole or 6.02*10^23 molecules of CO2 is 44 grams
Explanation:
The percent yield of a chemical reaction is calculated by dividing the actual yield (determined through experimentation) by the theoretical yield (calculations). The percent yield is a great way of determining the efficiency of a reaction. For this problem, the percent yield is 83.93% as given by the solution:
% yield = (47/56)*100 = 83.93%
