chemistry help, pleaseee?

Which orbital would first be filled by electrons? 4p, 4d, 5s, 5pThe ion O^2- hasAnsweran overall negative charge due to an electronan overall positive chargean overall negative charge caused by the extra two electronstwo extra protonsThe mass represented on the periodic table is an average of?all isotopes of the element based on percent abundanceall protons in an atom of the elementthe least abundant form of the elementprotons plus neutrons plus electronsElectrons are included when calculating the average atomic mass of an element.True FalseIdentify the element with the following set of quantum numbers:(2, 1, -1, +1/2)oxygenberylliumboronaluminumIn the electron configuration, 1s22s22p63s23p4 there are electrons in the 2p orbital.Answer681216Which orbital would be filled first by electrons.5s, 5p, 5d, 5f, 6s, 6p, 6d?

Answer:

um well i kinda interchange them in the oven, but thats not always a good ideaThe foil can get hotter or reflect light, which may burn ur goodiesnot too sure abt that thoAnd if ur doing sumthing like wrapping cookie dough up to put in the fridge to chill, DONT USE FOIL, lol.it keeps heat in, and the dough will NEVER chill.i learned that the hard way /
Wax paper contains wax, and can't be used under the broiler, because it'll melt/burn/set everything on fire.It's also hard to keep folded and you may need to use butter or shortening so it'll stick to your bakeware.It can also be used in the freezerAluminum foil can be used as a little tent to protect foods from direct heat.and use can use it to make a cute envelop for oven-roasting foods.Think veggies and such.And use can use it to broilExpensive brands are more thicker.Cheap brands have thinner foilHappy cooking and such.
