Answer:
0.185M sulfuric acid
Explanation:
Based on the reaction:
H₂SO₄ + 2KOH → K₂SO₄ + 2H₂O
<em>1 mole of sulfuric acid reacts with 2 moles of KOH</em>
Initial moles of H₂SO₄ and KOH are:
H₂SO₄: 0.750L ₓ (0.470mol / L) = <em>0.3525 moles of H₂SO₄</em>
KOH: 0.700L ₓ (0.240mol / L) = <em>0.168 moles of KOH</em>
The moles of sulfuric acis that react with KOH are:
0.168mol KOH ₓ (1 mole H₂SO₄ / 2 moles KOH) = 0.0840 moles of sulfuric acid.
Thus, moles that remain are:
0.3525moles - 0.0840 moles = <em>0.2685 moles of sulfuric acid remains</em>
As total volume is 0.700L + 0.750L = 1.450L, concentration is:
0.2685mol / 1.450L = <em>0.185M sulfuric acid</em>

Answer:
Combustion.
Explanation:
When burning a hydrocarbon (CxHy) with Oxygen the products are Carbon Dioxide and Water.
<span>1.49 x 10^22 atoms
First determine the molar mass of P2O5
Atomic mass of Phosphorus = 30.973762
Atomic mass of Oxygen = 15.999
Molar mass of P2O5 = 2 * 30.973762 + 5 * 15.999 = 141.9425
Now determine how many moles of P2O5 you have
0.500 / 141.9425 = 0.003523
Since there's a total of 7 atoms per molecule of P2O5, multiply the number of moles by 7 to get the number of moles of atoms you have.
7 * 0.003523 = 0.024661
Finally, multiply by avogadro's number (6.0221409 x 10^23) to get the total number of atoms.
0.024661 * 6.0221409 x 10^23 = 1.48512 x 10^22</span>
