First, you have to find now many moles of octane are present in 191.6g of octane. To do this you need to do this you need to divide 191.6g by its molar mass (which is 114g/mol). This will give you 1.681 moles of octane. Then you need to use the fact that 2 moles of octane are us ed to make 16 moles of carbon dioxide to find how many moles of carbon dioxide 1.681mole of octane produces. To do this you need to multiply 1.681mole by 16/2 to get 13.45mol carbon dioxide. The final step is to find the number of grams presswnt in 13.446 moles of carbon dioxide. To do this you need to multiply 13.446 mole by carbon dioxides molar mass (which is 44g/mol) to get 591.6 g of carbon dioxide.
Therefore, 591.6g of carbon dioxide is produced when 191.6 grams of octane is burned.
I hope this helps. Let me know in the comments if anything is unclear.
How does it what. i don’t know if there’s a photo but can’t see it
To form the value of 1500 in
scientific notation, it is
<span><span>
1.
</span>By simply
moving the period which separates the whole numbers from the decimal numbers
between 1 and 5. </span>

2.
</span>Thus, it
then becomes 1.5 </span>

3.
</span>Next, is
you have to count how many moves the period made from its point of origin
hence, for this value is 3</span>
<span><span>4.

the scientific notation for the number is 1.5 x 10^3</span>
C₃H₈ + 5 O₂ → 3 CO₂ + 4 H₂O
is a combustion reaction
Explanation:
In a combustion reaction a chemical substance (usually organic substances) are reacted with oxygen to form the most stable oxides and heat.
CH₄ + 2 O₂ → CO₂ + 2 H₂O
In a double displacement reaction two compounds exchange elements.
AB + CD → AC + BD
In a decomposition reaction a compound is split into simpler substances.
AB → A + B
In a synthesis reaction two elements are combined to form another compound. A + B → AB
In a single displacement reaction a compound exchange one of its elements.
AB + C → AC + B

<h3>
Answer:</h3>
4.3 miles
<h3>
Explanation:</h3>
We are given;
Distance of 22,704 feet
We are required to determine the number of miles in 22,704 feet
- To convert one unit to another we use conversion factors
- Therefore, we need to know the suitable conversion factor.
- That is, 1 mile/5,280 feet
- Thus, to determine the number of miles we multiply the number of feet with the conversion factor.
That is;
= 22,704 feet × 1 mile/5,280 feet
= 4.3 miles
Therefore, there are 4.3 miles in 22,704 feet
