Today, more than a century later, aluminum stands as the most abundant metallic element. Every year, the United States produces more than 5.6 million tons (5.1 million metric tons) [source: International Aluminu
You might think that at the atomic scale size doesn't matter but it turns out that's not the case! If you could take the sodium ions out of the aluminosilicate glass and replace them with larger potassium ions, the sheet of glass would experience compression. Imagine you have a net. ...
First, you need the total mass of potassium in this solution, which is obtained by multiplying the concentration in mg/L by the volume of solution in liters: (78.2 mg/L)(0.75 L) = 58.65 mg From the above equation, and with the valence of elemental potassium being 1, you have mEq =...
The elemental dissolution behavior of the above-described four samples was investigated in 0.01 M KCl prepared from Potassium chloride (suprapur, Merck). The measured sample area was approximately 0.01 cm2. A Pt-wire counter electrode and a reference electrode (Ag/AgCl/3 M KCl) were ...
How many grams of water would be needed to make a 0.56 M solution with 2.53 kg potassium phosphate? Assume the density of the solution is 1.23 g/mL. Give the answer in correct scientific notation. If a person has a mass of 62 kg, how many pounds of water does ...
Answer to: How does ionic size relate to the size of their particular parent atom? Discuss the relative size of the ions of potassium, bromine, and...
This is done very delicately as both sodium and potassium pull the water across the wall of the cells from the bloodstream into a collecting channel that leads to the bladder. When eating to much salt, the amount of sodium in the bloodstream will be imbalanced compared to the amount of ...
The renin-angiotensin-aldosterone (RAS) "cascade" of hormones can greatly influence how much water and what amount of each electrolyte (e.g., sodium, potassium) should be spared excretion. This allows the body to compensate for disruptions to the osmotic internal equilibrium very quickly. Serum ...
Potassium, K Leftmost seat, fourth row, yearning for the halogens on the other side. Radium, Ra Licked by the women painting luminous watches. How much time stolen? Of her forthcoming book, Lee says, "I will be happy if people enjoy 'Elemental Haiku.' I will be even happier if the ...
What do the three types of beta decay have in common that is distinctly different from alpha decay? Why are heavier elements not much larger than lighter elements? Why will the escape of neutrons be proportionally less in a large piece of fissionable material than in a smaller piece?
