I have a chemistry exam tomorrow, and I don't know how to explain salt formation. We didn't do any writing, my friend's is really incomprehensible, and the internet isn't exactly helping me. I'm already getting frustrated with the other topics. Can someone please seriously tell me what I should write in my paper?! Thanks in…
When formulating a reaction equation from a text, it's certainly helpful to work with the valences of the elements. However, this isn't possible with tungsten(VI) oxide. This should be done purely according to logic, W206. Addendum/insight: Could it be that they are shortening it, so that W2O6 becomes WO3?
If a reaction occurs, what do the reaction equations look like with ionized noble gases? x He 2+ + y H 2 → x Ar 2+ + y H 2 → x Ar 4+ + y Mg → x Xe 6+ + y O 2 →
How can I permanently darken a piece of precious metal so that it no longer shimmers? Is there, for example, an acid that can be made from household items? I don't want to paint, I would prefer to etch.
I would like to know why Cl only has a minus and under Cl there is a 2, so how does this relate
All organic compounds consist of carbon (C) and hydrogen (H).
Carbon dioxide (CO2) and water vapor (H2O) are always formed as gaseous main products during combustion.
Thank you.
