Consider the two electron arrangements for neutral atoms A and B. What is the difference between atom A and atom B? A - 1s22s22p63s1
B - 1s22s22p65s1

Atom B has lost some inner electrons.
The outer electron of atom B has moved to a lower energy state.
The outer electron of atom B has moved to a higher energy state.

The climate of the continental united states is generally 1. tropical 2. temperate 3. arctic 4. highland

A5.000 g sample of niso4 h2o decomposed to give 2.755 g of anhydrous niso4. what is the formula of the hydrate? what is the full chemical name for the hydrate? what is the molar mass of the hydrate? niso4•_h2o what is the mass % of water in the hydrate?

Each of the following reactions is allowed to come to equilibrium and then the volume is changed as indicated. predict the effect (shift right, shift left, or no effect) of the indicated volume change. drag the appropriate items to their respective bins.co(g) + h2o(g) < => co2(g) + h2(g) (volume is decreased) pcl3(g) + cl2(g) < => pcl5(g) (volume is increased) caco3(s)< => cao(s) + co2(g) (volume is increased)
