Answer:
The yield is 16 moles of CO2 per 2 moles of isooctane.
The mass of CO2 is 1.15 billion tonnes
Explanation:
First we set the unbalanced equation:

Now we proceed to balance the equation:

With the equation balanced, we see that the theoretical yield is 16 moles of CO2 per 2 moles of isooctane and we can proceed to make calculations with the following data:

Knowing the different relations between mass, density and molar mass, we have the following results:

Answer:
C. 0.35cm
Explanation:
The length indicated by the arrow along the ruler should recorded be recorded as "0.35cm".
This is correct because when counting the measurement on the ruler, the first line on the ruler is 0.1cm, the second line is 0.2cm, and so on. The spaces between each line is 0.05cm. So, the arrow is pointing on the space between 0.3cm and 0.4cm.
Therefore, 0.3cm + 0.05cm = 0.35cm.(answer).
CaO ( calcium oxide) is a basic oxide.

I think your answer choices are...
A. an educated guess
B. a statement of pure fact
C. a general principle based on an observable fact
D. a collection of data
Answer:
C. A general principle based on an observable fact
Explanation:
It can't be A as an educated guess is in scientific terms , a hypothesis.
It can't be B as that is a fact or a law
It can't be D as a collection of data is a data table.
