Al­­2(CO3)3 + 2 H3PO4 ---> 2 AlPO4 + 3 CO2 + 3 H2O If you have 6.0 moles of Al­­2(CO3)3, how many moles of AlPO4 are made?

sodium (na), for example, has one electron in its valence shell. this is an unstable state because that valence shell needs eight electrons to be full. in order to fill its valence shell, find a way to add seven electrons to its valence shell

im pretty sure its b

i think it's c. if you look search electronic symbol on google and then click on wiki it shows you a
