why is respiration considered an exothermic reaction? Explain.
Why are decomposition reactions called the opposite of combination reactions?
Write equations for these reactions.
Answers
Explanation:
C6H12O6 + 6O2 → 6CO2 + 6H2O + energy
It involves the burning of sugar with oxygen within the cells of every living organism, to produce the energy needed for all the reactions of life along with water and carbon dioxide as waste products. Respiration is another exothermic reaction
In a combination reaction two or more substances are combined to form new substance while in the decomposition reaction one substance decomposes into two or more substances. Hence, the decomposition reactions are called opposite of combination reactions.
Answer:
Respiration is considered an exothermic reaction because in respiration glucose food is completely broken down to form carbon dioxide water and light energy is released
Explanation:
C 6H12 O6 +6O2 =6CO2+6B2O+LIGHT ENERGY
#2 DECOMPOSITION REACTION ARE CALLED THE OPPOSITE OF COMBINATION REACTION BECAUSE IN DECOMPOSITION REACTION ONE COMPOUND BREAKS DOWN TO FORM TWO OR MORE ELEMENTS WHILE IN COMBINATION REACTION TWO OR MORE ELEMENTS COMBINE TO FORM A SINGLE COMPOUND
