Answer: The value of for the given reaction is .
Explanation:
The ratio of concentration of products and reactants raised to the power of their concentration is called equilibrium constant.
It is denoted by the symbol .
For example,
The expression for of this reaction is as follows.
So, by putting the respective concentrations of the species involved in the reaction it is possible to determine the value of for the given reaction.
Thus, we can conclude that the value of for the given reaction is .
Answer:
Explanation:
2C₈H₁₈ + 25O₂ → 16CO₂ + 18H₂O
The reaction above is a typical combustion reaction which are very common with hydrocarbons. Combustion occurs in the presence of oxygen to product carbon dioxide and water. The purpose of this reaction is to transform chemical energy into useful heat energy. Most times, the oxygen used is always in excess of the hydrocarbon reacting with it.
Answer:
The correct answer is a. The volume of the gas increases.
Explanation:
In this case, we apply Boyle Mariotte's Law: for a given gas mass at constant temperature, the pressure and volume vary inversely proportionally (the higher the pressure, the lower the volume and vice versa).
If the pressure reduced, the volume increases according to the formula: P1xV1 = P2xV2
Answer:
Carbon is the chemical backbone of life on Earth. Carbon compounds regulate the Earth’s temperature, make up the food that sustains us, and provide energy that fuels our global economy. Most of Earth’s carbon is stored in rocks and sediments. The rest is located in the ocean, atmosphere, and in living organisms. These are the reservoirs through which carbon cycles.The ocean plays a critical role in carbon storage, as it holds about 50 times more carbon than the atmosphere. Two-way carbon exchange can occur quickly between the ocean’s surface waters and the atmosphere, but carbon may be stored for centuries at the deepest ocean depths.
