Explanation:
Explanation:
The rest of the energy is passed on as food to the next level of the food chain. The figure at the left shows energy flow in a simple food chain. Notice that at each level of the food chain, about 90% of the energy is lost in the form of heat.
Far apart and have weak attractive forces between them
Answer:
3 o2(g)
Explanation:
the reaction releases 3 moles O2 --- enthalpy per mole
just divide -284.6 / 3
neg. heat of reaction (enthalpy) means energy is released by the reaction
