A ecosystem is SUSTAINABLE if it can continue to function over long periods of time.
A combustion reaction usually happens when a hydrocarbon is reacted with an oxygen molecule producing water and carbon dioxide. It is an exothermic reaction which means it releases heat as the process proceeds. It is a spontaneous process where it readily happens without any supply of energy. The total kinetic energy of the reactants is greater than the activation energy that is why heat is being released. Acetic acid is a carboxylic acid and is classified as a hydrocarbon so when reacted with oxygen, it would yield carbon dioxide and water. The balanced chemical reaction would be as follows
CH3COOH + 2 O2 = 2 CO2 +2 H2O
Some rocks contain carbonate minerals, and the acid test can be used to help identify them.
Answer:
D. Use x-ray radiation to see if there are any fractured bones.
