Magnesium phosphate is used as a dental polishing agent. how many moles of ions (cations and anions together) are in 1 mole of magnesium phosphate, mg3 (po4) 2?

Which force attracts one atom's protons to another atom's electrons?

When 3.54 grams of phosphorus react with excess oxygen gas to produce diphosphorus pentoxide, the percent yield is 84.1%. What was the actual yield of the reaction? 4P 5O2 yields 2P2O5

In the chemical formula 3NO2 the number 3 is a

W (g) + X (g) - -> Y (g) + Z (g) Gases W and X react in a closed, rigid vessel to form gases Yand Z according to the equation above. The initial pressure of W (g) is 1.20 atm and that of X (g) is 1.60 atm. No Y (g) or Z (g) isinitially present.

In this process, a piece of paper with small holes in it separates a heterogeneous mixture by letting through the small particles and keeping out the big ones. That is called as
