How many chlorine atoms are in 4.3 grams of phosphorous trichloride? If sodium and potassium are both ions with a positive charge, how can they make something negative? Why does an electron cloud want to have a stable amount of electrons per energy level?
Which of the following sets of molecular ions does an alkyl bromide possess? a. two molecular ions in a 2:1 ratio separated by two mass units. b. two molecular ions in a 1:1 ratio separated by two mass units. c. three molecular ions in a 1:2:1 rat...
Lead L. Strontium M. Zinc What does water dissociate into? Does lithium react with cold water? How reactive is nobelium? What releases hydrogen ions in water? How is an ionic compound formed? What are sulfates in water? Does lawrencium conduct electricity? What is the result of dissociation...
for example, strontium (atomic number 38) produces a reddish color, while sodium (atomic number 11) produces a yellowish color. The sodium ion has a stronger affinity for the electron, so more energy is required to move the electron. When the electron does move, it reaches ...
Child derived this equation applicable to vacuum tube theory in 1911 for the case of atomic ions. These have much smaller ratios of their charge to their mass. Irving Langmuir extended the basic law when he published the application to electron currents in 1913. This extended it to...
If the fast rinse cycle were too long it might remove the newly-charged salt ions attached to the resin grains and the water softener wouldn't have capacity to soften the building water supply when the unit returns to service. Softener Regen Step #5 - refill the brine tank During the la...
Fission products (e.g.79Se,135Cs) and minor actinides can have a high radiological impact on the environment during operation and severe accidents of nuclear power plants and on the residual heat production during storage of spent nuclear fuel. Correspondingly, high attention has to be paid in...
Plus, they have a lot to offer in terms of nutrition. Both the flesh and peel of sweet potatoes contain many key bone-healthy nutrients, like vitamin C, magnesium, and potassium. Specifically, one medium sweet potato with its skin intact provides 542 mg of potassium. So keep the peel to...
Myself and many thousands of others, have witnessed planes flying so low you can see the plane company logo/colours (Or have tracked the plane on Flight Radar to identify it), leaving both persistent and non persistent trails. The additives are added to the jet fuel system and this is ...
Natural gas production from the Marcellus Shale formation has significantly changed energy landscape in recent years. Accidental release, including spills, leakage, and seepage of the Marcellus Shale flow back and produced waters can impose risks on natural water resources. With many competing processes...
