I'm studying for IGCSE Chemistry and I'm a little confused with Bonding/Molecules.
My textbook says:
"Molecules are held together by covalent bonds"
I'm a little confused by this as I thought a molecule was formed when two or more atoms (same or different elements) join together...
I came here from https://www.physicsforums.com/threads/i-dont-understand-how-hcl-is-not-a-ionic-bond.449393/ where replies are no longer allowed. I wanted to reply to suggest a few things:
High school students who like chemistry are far smarter than anyone will give them credit for.
I need to draw NH4NO2 which is an ionic compound.
3. The Attempt at a Solution
NH4 is fairly straightforward to draw, with one N in the middle and four H surrounding, and no lone pairs. The problem comes with NO2- which is one nitrogen bonded to two oxygens. However, one...
Write the balanced chemical reactions in ionic and neutral forms for:
i) Enargite leaching by sodium bisulfide in basic solution to form chalcocite and thioarsenate.
ii) Oxygen pressure oxidation of As2S5 in acid solution to form scorodite. Assume all sulfide sulfur forms...
