This is a combustion reaction, which always has the hydrocarbon and oxygen as reactants and then carbon dioxide and water (which is steam in this case) as products.
C8H18 + O2 —> CO2 + H2O
Balance your carbons first. You want to get 8 carbons on both sides.
C8H18 + O2 —> 8CO2 + H2O
Now balance your hydrogens. You want 18 hydrogens on both sides.
C8H18 + O2 —> 8CO2 + 9H2O
Now balance your oxygens. You have 2 on the left and 25 on the right. The O2 reactant needs a coefficient of 12.5 to balance this.
C8H18 + 12.5O2 —> 8CO2 + 9H2O
However, you can’t have decimals for coefficients in a reaction. So, multiply everything by 2.
2C8H18 + 25O2 —> 16CO2 + 18H2O
Now, use your mole ratio of 18 mol H2O for every 2 mol C8H18 to solve.
5.74 mol C8H18 • (18 mol H2O / 2 mol C8H18) = 51.7 mol H2O (steam)
Answer:
Take in carbon dioxide, reduces water loss, and produce oxygen.
Explanation: Hi! I've learned about these things in the past, really tough stuff! Hopefully this helps, I believe the three options above are correct, only one I'm possibly questioning is producing oxygen. Good luck!
Answer:
iron have magnetic features which connects with magnets. That's why it's used to visualise
Answer:
The answer to your question is: Al, Si have the greatest and S, C have the smallest.
Explanation:
Atomic radius increases from right to left in the periodic table.
Atomic radius increases from the upper section to the lower section of the periodic table.
Order of the atomic radius from highest to lowest.
