Answer: it's 3CO2+4H2O+Energy
Propane is a linear alkane of formula C3H8. It is mainly used as fuel (this is the main component of liquefied petroleum gas) in cooking and chemical industry reactions.
The reaction of its complete combustion by the presence of oxygen is:
C3H8 (gas) + 5O2 ==> 3 CO2 + 4H2O + energy (2220⋅kJ)
As we can see, propane can release carbon dioxide and water as every combustion reaction, and a lot of energy in the form of heat.
Answer:
Reservoirs
Explanation:
Glaciers serve as reservoirs in the water cycle since they can store water for long periods of time. A biogeochemical or nutrient cycle is composed of
- reservoirs, in which the biogeochemical or nutrient is stored, and
- the several processes by which the biogeochemical or nutrient is cycled between its reservoirs.
The answer is respiration.
The burning of fossil fuels is known as combustion. It is often compared with cellular respiration.
The general equation of cellular respiration is:
glucose + oxygen → <span>water + carbon dioxide
</span>
The general equation of combustion is:
fuel + oxygen → <span>water + carbon dioxide
Both reactions involve breaking down of large molecules (glucose and fuel) using oxygen into water and carbon dioxide. In both reactions, chemical energy is transformed into more useful form.</span>
Answer:
D- Estuary
Explanation:
estuaries are where the tide meets a stream, they happen above the water/not very deep in the water
