Can someone me with chemistry? write the complete balanced equation for the reaction that occurs when aluminum phosphate (alpo4) reacts with magnesium chloride (mgcl2) in an aqueous solution. i got 2alpo4 (aq) + 3mgcl2 (aq) -> mg3(po4)2 (s) + 2alcl3 (aq) is this right?

1) how many electrons are in each energy level of the following elements? a. he b. na c. na d. ne 2) how many valence electrons are percent in the following atoms? a. s b. mg c. be d. cl 3) which of the following elements are stable as atoms? a. he b. o c. cl d. ar if you are able to provide the work as to how you got the answers that would be greatly appreciated. : )

What is the percent composition of ca(oh)2? 37.7% ca, 53.0% o, and 10.3% h 45.5% ca, 38.2% o, and 16.3% h 54.0% ca, 43.0% o, and 2.7% h 64.7% ca, 27.0% o, and 8.3% h

Achemical reaction is done in the setup shown, resulting in a change of mass. what will happen if the same reaction is done in a sealed container that is placed on the electronic balance?
