Question

can you please confirm the correct answer​

Answer 1

Answer:

Molecular mass of -

a_ H2SO4 = 98 g/mol

b _ C6H12O6 = 180 g/mol

Respiration is considered as an exothermic reaction because energy is liberated by the reaction.

Explanation:

a_ H2SO4 =

Molecular mass of H2SO4 = {(molar mass of H)×2} + { ( molar mass of sulpher)} + {( molar mass of oxygen)× 4}

= 2×1 + 1× 32 + 4× 16

= 2 + 32 + 64

= 98 g/mol

b_ C6H12O6 =

Molecular mass of C6H12O6 = {(molar mass of carbon)×6} + {(molar mass of hydrogen)× 12} + {( molar mass of oxygen) × 6}

= 12×6 + 1 × 12 + 16× 6

= 72 + 12 + 96

= 180 g/mol

Respiration is the catabolic break down of glucose when it combines with oxygen to release energy 32 ATP.

So in respiration oxygen combines with glucose(C6H12O6) to release carbon dioxide(CO2),water(H2O) and heat.

Reaction:

C6H12O6 + O2 = CO2 + H2O + Heat
