Answer:
1.13×10^25 molecules of water.
Explanation:
Equation of the reaction;
C8H18(g) + 25/2 O2 (g) -------> 8CO2(g) + 9H2O(l)
It is important to first put down the balanced reaction equation. It is not possible to solve any problem on stoichiometric relationship without a balanced reaction equation. Once the equation is obtained, we can now proceed with other steps in the solution of the problem.
From the reaction equation, 1 mole of C8H18 produces 9 moles of water
1 mole of C8H18 occupies 22.4L volume while 1 mole of water contains 6.02×10^23 molecules of water
Hence
22.4 L of C8H18 produces 9(6.02×10^23) molecules of water
46.72 L of C8H18 will produce 46.72 L × 9(6.02×10^23) molecules of water/22.4 L
= 113×10^23 or 1.13×10^25 molecules of water.
Answer:
The answer to your question is 0.3 moles of NaCl
Explanation:
Data
NaCl = ?
Al(NO₃)₃ = 0.1 moles
Balanced reaction
Al(NO₃)₃ + 3NaCl ⇒ 3NaNO₃ + AlCl₃
Now, use proportions to solve the problem
1 mol of Al(NO₃)₃ ------------ 3 moles of NaCl
0.1 moles of Al(NO₃)₃ -------- x
x = (0.1 x 3) / 1
x = 0.3 moles of NaCl
The conversion of ethanol to ethanoic acid is an oxidation reaction.
