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...
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...
NCERT solutions for CBSE and other state boards is a key requirement for students. Doubtnut helps with homework, doubts and solutions to all the questions. It has helped students get under AIR 100 in NEET & IIT JEE. Get PDF and video solutions of IIT-JEE Mains & Advanced previous year pap...
This paper reports the discovery that water can trigger a peculiar nuclear reaction and produce energy. Cavitation may induce unusual reactions through implosion of water vapor bubbles. Many of this research has been published formally or informally. We have conducted experiments using two reactor types...

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...
