The standard heat/enthalpy of formation of SO2 is -296.8 KJ
S(s) + O2(g) SO2(g) + 296.8 kJ
The most straightforward reaction for the formation of SO3 from SO2 is 2 SO2 + O2 => 2 SO3. If this is the actual reaction for the formation, 3 moles of SO3 are formed from 3 moles of SO2.
The heat source for rock formation is primarily the Earth's internal heat, generated by the decay of radioactive elements in the planet's core. This heat causes rocks to melt, leading to the formation of igneous rocks. Additionally, pressure from tectonic forces can also contribute to the formation of rocks.
To determine the number of moles of SO2 in 0.45 grams of sulfur dioxide, you need to use the molar mass of SO2. The molar mass of SO2 is about 64.06 g/mol. Divide the given mass by the molar mass to find the number of moles. In this case, 0.45 grams divided by 64.06 g/mol gives you approximately 0.007 moles of SO2.
When sulfur dioxide reacts with water, it forms sulfurous acid, which is a weak acid. The chemical equation for this reaction is SO2 + H2O → H2SO3. This reaction can lead to the formation of acid rain, which can have detrimental effects on the environment.
2KOH + H2SO3 --------> K2SO3 + 2H2O or K2O + SO2 ------> K2SO3
S(s) + O2(g) SO2(g) + 296.8 kJ
1/8 S8 + O2 --> SO2 , delta H degree f = -296.9 kJ
adding SO2
SO2 is harmful because it can irritate the respiratory system, leading to symptoms such as coughing, wheezing, and shortness of breath. Prolonged exposure to high levels of SO2 can exacerbate conditions like asthma and increase the risk of respiratory infections. Additionally, SO2 can contribute to the formation of acid rain, which can harm ecosystems and infrastructure.
Yes, SO2 (sulfur dioxide) can dissolve in water to form sulfurous acid (H2SO3). This process involves the dissolution of SO2 gas molecules into water molecules, leading to the formation of hydrated sulfurous acid. The dissolution of SO2 in water is an important step in atmospheric chemistry, as it contributes to the formation of acid rain.
The most straightforward reaction for the formation of SO3 from SO2 is 2 SO2 + O2 => 2 SO3. If this is the actual reaction for the formation, 3 moles of SO3 are formed from 3 moles of SO2.
S (sulphur) + O2 (oxygen) = SO2 (sulphurdioxide)
The heat of formation for H2 is 0 kJ/mol.
When kerosene vapor is burned, it undergoes combustion to produce carbon dioxide, water vapor, and heat. Incomplete combustion can also result in the formation of carbon monoxide and soot particles.
The heat of formation of zinc nitrate is -2304 kJ.
The heat of formation changes with temperature. At higher temperatures, the heat of formation tends to increase, while at lower temperatures, it tends to decrease.
