Cu ions plus EDTA2- ->cu(EDTA)2- plus 2H-
number of moles of CU ions used which is equal to molarity multiplied by volume in litres
that is 50xo.o2 divided by 1000 that is 0.001moles
Since ratio is 1:1 the moles of EDTA is also0.001moles
volume of EDTA is 0.001 divided by 0.0510m which is 0.0196 litres in ml is 0.0196x1000 which is 19.61ml
15 miles MGCI..... I think
Valence electrons form bonds to create molecules and compounds because A. they are weaker than the electrons found closer to the nucleus.
A better way of saying it is that the valence electrons are <em>less strongly attracted</em> to the nucleus.
All electrons have the same size, but the <em>orbitals</em> they occupy have different sizes.
Kinetic energy maybe or something
Our bodies and plants bodies produce glucose which helps give us energy. Glucose comes from food and fats from the things we eat eve
