A: In order for the contrail to form, there must be enough moisture in the high levels of the atmosphere for the ice crystals to form around the airplane exhaust. If the upper atmosphere is very dry, contrails will not easily form, or will be of the short-lived type. Q: Do contrail...
Write Lewis formulas for the reactant and product species in the following chemical equation. Include nonbonding electrons.2OH(g) → H₂O₂(g) The OH molecule has 7 valence electrons. Since 7 is an odd number, there will have to be a radical electron in this molecule. Hydrogen can ...
The application of quantum-mechanical methods to chemical problems led to the development of quantum chemistry with the goal of solving the Schrödinger wave equation for the many-electron systems of molecules. One of the first results was the theory of valence bonds, which still retained the tra...
Life on planet Earth is a complicated and well-organized set of processes. Animals are designed to breathe oxygen and plants are designed to produce oxygen. Photosynthesis is the means by which we get the oxygen we need for life. Light striking a plant pigment known as chlorophyll initiates a...

a convention known informally as "electron pushing." A covalent bond consists of a shared pair of electrons. Nonbonded electrons important to the reaction mechanism are designated by dots. Curved arrows represent the movement of electron pairs. For movement of a single electron (as in a free ra...
The CA effect equation (Eq. 3) was used to calculate the total HQ for a mixture of compounds in a sample for each site and season (Ginebreda et al., 2010). Throughout the manuscript this is referred to as ∑HQ.(3)∑HQi=∑jhqijwhere: ∑HQi = the hazard quotient of the sample i...
At this time, the demand for urban heating increases, and a large amount of carbon-containing fossil fuels are burned, causing XCO2 to rise in the winter. In spring, vegetation activity begins to recover. Since photosynthesis has not reached its maximum level, and soil decomposition and ...
and handling capacity and facilities. Toxic waste has been utilized as biomass in pyrolysis processes to generate biochar for soil application and has resulted on spreading of toxic elements in the soil that ends up polluting the environment, abetting GHGs emission and suppression of the effectiveness...
