The model of the atom has dramatically changed over many many years.We learned atoms make up different substances and are the smallest particles of matter, which have subatomic particles that are very small portions of matter. At first scientist only thought there were electrons which are negatively charged.
Natural selection leads to evolutionary change when individuals with certain characteristics have a greater survival or reproductive rate than other individuals in a population and pass on these inheritable genetic characteristics to their offspring.
C i think i got this off of usa test prep in class
it makes aloh
AlCl3 + 3NaOH = AlOH3 + 3NaCl
Al3+ + 3Cl- + 3Na+ + 3OH- = AlOH3 + 3Na+ + 3Cl-
all cancels out except
Al3+ + 3OH- = AlOH3
Explanation:
To determine the charge on a given transition metal atom, you have to consider what element it is, the charges on the other atoms in the molecule, and the net charge on the molecule itself. The charges are always whole numbers, and the sum of all the atomic charges equals the charge on the molecule
