at Math and Chemistry... I thought I was understanding how to solve atomic mass and now I can’t figure out this question. I asked my prof for help but he used an example where we were given abundance and amu for all the isotopes and just had to use the average atomic mass formula...
the compound CuF2will be written as copper (II) fluoride, determined because the fluoride ion charge is always 1-, so the balancing copper ion has to have a 2+ charge. Using this model, the formula for iron (III) chloride has to be FeCl3because iron...
Creating chemical formulas from compound names is a straightforward process. For nonmetal compounds, use the prefixes in the chemical name. For ionic compounds, use a crisscross method of charges; and to find an empirical formula, use the molar masses of
In simple words, we can say that a capacitor is a device used to store and release electricity, usually as the result of a chemical action. Also referred to as a storage cell, a secondary cell, a condenser or an accumulator. A Leyden Jar was an early example of a capacitor....
