for each of the following ions indicate the total number of protons and electrons in the ion for the positive ions in the list, predict the formula of the simplest compound formed between each positive ion and the oxide ionfor the negative ions in the list, predict the formula of the simplest compound formed between each negative ion and the aluminum ion.AFe2+B.Fe3+C.Ba 2+D.Cs+E.S2-F.P3-gBr-hN3
al reflects heat you are slightly confused energy comes in many formsheat is one Tem0erature is the measure of average energy sunlight heats the surface that absorbs the energythe temperature rises and the hotter surface LOSES energy to cooler sourroundings, including by radiation the energy has to be trapped or captureded( by the darker ground) darken the foil with soot or black paint Protect it from the cooling air inan insulated box ( like the inside of a car) it is easy to make a solar cooker that can almost boil water on a hot day it does NOT take 158 deg to fry the eggtaht is quickit can be slow cooked at only a little above 100 ( i think) try itgood school science experiment how cool can you still cook and egg?
The aluminum foil won't get hotIt reflects heat, but doesn't absorb itThis is why when you cook certain things in an oven, it's recommend that you line them with foilIt helps get more of the heat to the food in a more evenly distributed wayThis is also why if you pull something out of the oven by the foil that you cooked it on, you can touch the foil directly and won't burn your hand at all.
I saw it happen at a small hotel where my mom workeda guy was frying an egg in a black pan on the ground in the suntry a black pan instead of foil Also, we made a Solar oven in the 4th grade, im not sure if this is exactly how we did it, but we made s'mores with it: box (like a cake box from big y) take the clear top out of the box replace it with plastic wrapput foil on the floor of the box, put your egg/s in itclose it for a while in the sunthe foil reflects the heat around the box and heats it up.
For all atoms the number of protons atomic number, so just look it up.ALso for atoms, no of protons no of electons, so you know that, tooFor positive ions, you must have LOST electons, so to determine how many electron each positive ion has, it's (atomic number - charge on the ion)For negative ions, you must have GAINED electrons, so no of electrons (atomic number + charge) egO has 8 protons, so also has 8 electrons O^2- has (8 +2) 10 electrons Work the rest out yourself! The oxide ion (O^2-, above) has charge 2-, so you must cancel that out with your cations aFeO bFe2O3 cBaO dCs2O The aluminium ion is 3+, so e.Al2S3 fAlP gAlBr3 hAlN
