I was asked to write the reaction for the formation of zinc iodide from zinc and iodine, so I put down ZnI, after looking on the net i found that it is actually ZnI2, but how am i supposed to figure out that the charge of Zn is 2+, because i thought that you coudlnt figure ...
On the periodic table of elements, transition metals are elements with partially filled d orbitals, or that have the ability to form partially filled d orbitals. An orbital is a location in an atom where we'll most likely find an electron (a negatively charged subatomic particle); they ...

What is CH3CH2CH2Oh after oxidation? What is the oxidation number of bromine in the BrO_3^- ion? What is the oxidation number of zinc? What is the oxidation number of carbon in NaHCO3? What is the oxidation number of the sulfur atom in H2SO4?
The charged chemical species known as ions are crucial in many different aspects of biology, industry and science. An example of an important ion is the positive hydrogen atom, H+, which is responsible for making solutions acidic. Electrolytes and ions a
the best way to charge your phone to extend battery life is to keep it between 20% and 80% most of the time. this is because lithium-ion batteries, which are commonly used in smartphones, have a longer lifespan when they're not regularly charged to 100% or drained to 0%. also, ...

Step 4: Use Charge Ratio to Find Calcium's Coordination Number The charge ratio between the fluoride ions and calcium ions is 2:1 (since there are two fluoride ions for each calcium ion). Since the coordination number of the fluoride ions is 4, we can use the charge ratio to find the...

“Their ability to perform safe charging over their life is also a concern. And they are expensive ($600-$1,000),” Ioxus’ Hall said. Moeller of Remy recommended proceeding with caution when selecting lithium-ion batteries. “Lithium is a very volatile material when ex...
