How can one know the possible ways to distinguish solutions made up of different ions? Explain why Zr4+ ion exists? How do you know if something is an ionic compound by the way it reacts? Comment on the relative acidities of and the ion. ...
How do you know if something is an ionic compound by the way it reacts? Describe the process that causes solutions of certain metal ions to be acidic. What difference does a different anion make to the emission of the cation tested?
Electronegativity values can help you determine if a bond between two atoms is likely to be covalent or polar covalent. In order to do this, you find the absolute value of the difference between the electronegativities of the two atoms. Based on this difference, the following table tells you...
Calculate the number of moles for any compound in the balanced equation for which you know the mass. The masses of all other substances can be calculated from the mass of just one product or reactant. In the case of the balanced reaction Ca(OH)2 + 2 HCl → CaCl2 + 2 H2O, to calcul...
Science took thousands of years to explain what exactly this sensation is that we all crave, and chefs and cooks know so well. Examples of umami-rich foods in global cuisines include lamb daube (stew) with anchovy in Mediterranean cooking; bagna cauda (warm dipping sauce of anchovies, garlic...
When making a solution, it's handy to know if one thing will dissolve in another. After all, if somebody wants you to make them a liquid solution of one chemical, it won't make you look good if you bring them a beaker of liquid with sludge sitting at the bottom because you chose ...
When a cancer supplement has been around for years, especially if it is popular, you'll hear how it has beat cancer. But what you don't know is its success rate. It may have been successful only a very small percentage of the time. -- Given the number of people who die from cancer...

First, the current energy density limit of liquid lithium-ion batteries is about 280Wh/kg. Even if silicon-based alloys are introduced into the negative electrode, it is difficult to break through the upper density limit of 400Wh/kg.
How do you know if something is an ionic compound by the way it reacts? Do strontium, magnesium, and calcium form +2 ions? Explain. Why do nonmetals tend to form anions when they react to form compounds? Ionic compounds are made up of electrically charged particles, Why does not such ...
