Answer:
It would take 5 days
Explanation:
1. 2.5 times 8 is 20 ounces
2. 2.5 times 16 is 40 ounces
3. 2.5 times 24 is 60 ounces
4. 2.5 times 32 is 80 ounces
5. 2.5 times 40 is 100 ounces
Answer:
the last answer is right.
Answer:
3224 kJ/mol
Explanation:
The combustion of benzoic acid occurs as follows:
C₇H₆O₂ + 13/2O₂ → 7CO₂ + 3H₂O + dE
The change in temperature in the reaction is the change due the energy released, that is:
3.256K * (10.134kJ / K) = 33.00kJ are released when 1.250g reacts
To find the heat released per mole we have to find the moles of benzoic acid:
<em>Moles benzoic acid -Molar mass: 122.12g/mol-:</em>
1.250g * (1mol / 122.12g) = 0.0102 moles
<em />
The dE combustion per mole of benzoic acid is:
33.00kJ / 0.0102moles =
<em>3224 kJ/mol </em>
