Determine charges of ions?
Hi, I have a chemistry test coming up and I have no idea how to determine the charges of ions. Could someone please explain this to me in simple terms?
Can someone please reply as soon as possible?
Hello! My idea is to improve an alcohol-based skin disinfectant (such as that used before blood draws and other punctures) so that it has an intense color when sprayed (preferably a strong blue or green, for visibility on the skin), which then fades through contact with air and finally disappears when the disinfectant has evaporated….
Have at school d React copper oxide with propanol to form elemental copper. And in the work we have to set up a reduction equation, so I wanted to practice it now, but I'm very unsure if it's correct. Can someone please help me? Does anyone know of any websites where I can practice this…
Good evening, I'm currently doing some calculations, but I'm stuck. I would be very grateful if someone could help me. my task is A substance A decays according to first-order kinetics. You determine that after 72 hours, 60% of the initial concentration remains. Use this information to calculate the rate constant and half-life. Unfortunately, I…
Question is above, please don't explain it so complicated
Hello everyone Can someone explain to me in a simple and understandable way what a charge is? Is an electron a single charge, or are there many charges within an electron? Thanks and greetings
You’ve learned something about octet rule and noble gas configuration in earlier chemistry hours. Which atomic species, like many electrons, absorbs or emits to achieve the noble gas configuration.
This was in the context of the question of how many bonds which make the atom. But it also works 1:1 for the way from the atom to the ion.
The few side-group elements that you need in chemistry lessons, you have to remember. So what charges these preferably accept.
