Halides, oxides and sulfates are examples of what minerals? What do sulfate minerals contain? How do ions form ionic bonds? What are sulfide minerals? How many atoms are in lithium hydroxide? What do all oxide minerals have in common?
The numbers to the right and just below each of the chemical symbols tell how many of the respective atoms are in one molecule, or formula unit, of the compound if there be more than one of that type of atom in the compound.Answer and Explanation: ...
Chemists use equivalent units, or equivalents, to express the reactive capacity of a chemical species, such as electrons or ions like H+. The equivalent defines how many electrons or ions may be transferred in a chemical reaction. For example, in the aci
How many moles of CH_4 (methane) is equivalent to 20.6 grams of CH_4 assuming the molar mass of methane is 16.04 g/mol? How many moles are in 9.8 grams of calcium? Calculate the number of moles of methane in 8.7\times 10^(23) molecules of methane and the number of atoms. ...
How many milligrams of {eq}\rm C_2H_6O {/eq} are in a {eq}\rm 0.085\ mol \cdot L^{-1} {/eq} solution with a volume of {eq}\rm 84.2\ mL {/eq}?Molar Solution:The term "molar solution" refers to the corresponding molarity of a solution. For example...
When you connect a battery's two electrodes into a circuit (for example, when you put one in a flashlight), the electrolyte starts buzzing with activity. Slowly, the chemicals inside it are converted into other substances.Ions(atoms with too few or too many electrons) are formed from the ...
Acids and alkalis are simply chemicals that dissolve in water to form ions (atoms with too many or too few electrons). An acid dissolves in water to form positively charged hydrogen ions (H+), with a strong acid forming more hydrogen ions than a weak one. An alkali (or base) dissolves...
(Notice that if the two atoms being compared are in the same row of the periodic table, the atom farther to the right is the more electronegative atom; if the atoms being compared are in the same column, the one closer to the top of the column is the more electrone...
A main advantage of non-soap bars is that they are formulated not to leave soap scum in hard water. In fact, one of the reasons non-soap products were developed was that soap doesn't do so well in hard water. Water is considered to be hard when it has minerals such as calcium and...
