A 1.250-g sample of benzoic acid, C7H6O2, was placed in a combustion bomb. The bomb was filled with an excess of oxygen at high
Degger [83]

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>

What is the meaning of cryosphere
nikklg [1K]

Answer:

The part of the earth’s surface where, at temperatures below 32°F (0°C), the water is frozen solid. Even a small pond while frozen over during the winter is part of the cryosphere, but cryosphere refers more often to large regions covered in snow and ice for much or all of the year, as the ice sheets of Antarctica and Greenland, glaciers, icebergs, and expanses of permafrost, all of which are especially sensitive to global shifts in climate:
