ammonium phosphate is an important ingredient in many solid fertilizers. It can be made by reacting aqueous phosphoric acid with

liquid ammonia. Calculate the moles of ammonium phosphate produced by the reaction of 2.4 mol of ammonia. Be sure your answer has a unit symbol, if necessary, and round it to significant digits.

Answer:

0.57 moles (NH4)3PO4 (2 sig. figs.)

Explanation:

To quote, J.R.

"Note:  liquid ammonia (NH3) is actually aqueous ammonium hydroxide (NH4OH) because NH3 + H2O -> NH4OH.

H3PO4(aq) + 3NH4OH(aq) ==> (NH4)3PO4 + 3H2O  

Assuming that H3PO4 is not limiting, i.e. it is present in excess

1.7 mol NH4OH x 1 mole (NH4)3PO4/3 moles NH4OH = 0.567 moles = 0.57 moles (NH4)3PO4 (2 sig. figs.)"

A polonium atom has 84 protons, 124 neutrons, and 84 electrons. What will it change to during alpha decay? A. A lead atom with 8
77julia77 [94]
I think the correct answer would be A. When a polonium atom with 84 protons, 124 neutrons, and 84 electrons undergoes alpha decay, a lead atom would be produced with 82 protons, 122 neutrons, and 84 electrons together with an alpha particle having two protons and two neutrons.

Count the total number of atoms in the chemical formula 5H2O2
SVEN [57.7K]

Answer:

20 atoms

Explanation:

There are 4 in H2O2 because of 2 hydrogens and 2 oxygens.

Then, multiply by 5 because the coefficient is 5, therefore there are 5 H2O2 molecules.

5 x 4 = 20
