If there are 5 electrons in the outer shell of an atom, how many bonds can it make with hydrogen? Also, can hydrogen exist with one electron in the outer shell? If an element has atomic #32 how many electrons does it have? Aside from hydrogen and helium, a...
A hydrogen atom is in the n = 2 state. How much energy, in eV, must be absorbed by the atom for it to become ionized from this level? Can atoms only have up to 2 energy levels? If so, why is that? If not, how many energy levels can they have...

athe reversible hydrogen releasing and restoring reaction below 673 K would be associated with hydrogen combined with Mg. 发布和恢复反应的反演性氢在673 K以下同与镁结合的氢联系在一起。[translate] aPlease have a look at the post above, there you can find good informations 请看一看岗位上面,那里...
We have conducted experiments using two reactors made from concentric multiple-pipe heat exchanger and found that, when water is flowing through a tiny space and heated, it produces peculiar excess heat probably by cavitation and dynamic implosion of nanobubbles11. Water used in the experiments is ...
aIt is well known that higher hydrogen concentration on the catalyst facilitates the formation of methane and shorter chain length hydrocarbons 它是知名的更高的氢含量在催化剂促进甲烷和更短的链长碳氢化合物的形成[translate] asearch cf 搜索 cf[translate] ...
From a simple engineering viewpoint, hydrocarbon fuels are by far the most appropriate sources of energy for most of the needs of our technology. For example, methane is the ideal form of hydrogen for many heating applications. Liquid hydrocarbons are the fuel most suited for mobile applications...
We can determine the amount of air pollution from the toxic sulfur dioxide gas, SO_2 produced in the smelting of zinc sulfide, ZnS using the equation below. What is the percent yield if only 305 grams of sulfur dioxide gas, SO_2 is actually isolated? When the gas is hydrogen sulfide...
