arge atoms require low ionization energy while small atoms require high ionization energy. How?
I dont agree as it should be easier to remove electrons from greater radius shell of an atom.-I think y
AP Chemistry a week behind and I really need help :(
Please show work.
The ideal gas law is used to solve for an unknown variable for a given sample of gas. As in the ChemScope, pressure is measured
So I did a lab which involved adding an excess of hydrochloric acid to half a spoonful of sodium bicarbonate (baking soda). The hydrochloric acid was added by using a dropper, and we were told to stop
a 7.0 liter balloon at room temp (22°C) contains hydrogen gas. if the balloon is carried outside where the temp is -3°C, what volume will the balloon occupy?-6.4 l if the pressure is assumed constant.
I have read on internet in the following website that if early atmosphere contained oxygen, then amino acids, sugars, purines etc. would never have existed because they react with oxygen to form CO2 a
The transition metal complex has a ligand field splitting Delta0 = 179 kJ/mol. What
wavelength will the complex absorb?-Looks like its about 668 or 669nm.
This site shows the formula:

It was in chem class for a lab and it was literally only a drop. I put on hand sanitized afterwards and washed my hands.-no, there is no danger.
next time, use water first. then use the hand sanitizer
Calculate the molarity, molality, and density of a solution prepared by mixing equal volumes of 30% by mass of H2SO4 whose density is 1.218g/mL & by 70% mass of H2SO4 of density 1.61 g/mL so that the
when you eat a slice of pizza, the crust is often less hot than the toppings and sauce. why does this occur?
i know that heat goes from hot to cold, but doesnt it try to balence it out so everything i
We did a acid-base titration lab where we added NaOH to a vinegar mixture with phenolphthalein. Not even sure I got the reactant part right xD! thanks in advance!-Balanced equation:
CH3COOH + NaOH = H
Short and simple answers please..thanks. TGOD ;)-A chemical reaction is a process that leads to the transformation of one set of chemical substances to another. Chemical reactions can be either sponta
