Aqueous potassium phosphate was mixed with aqueous magnesium chloride, and a crystallized magnesium phosphate product was formed
scoray [572]

<u>Answer:</u> The other product formed is potassium chloride.

<u>Explanation:</u>

Precipitation reaction is defined as the chemical reaction in which an insoluble salt is formed when two solutions are mixed containing soluble substances. The insoluble salt settles down at the bottom of the reaction mixture.

The chemical equation for the reaction of potassium phosphate and magnesium chloride follows:

2K_3PO_4(aq.)+3MgCl_2(aq.)\rightarrow Mg_3(PO_4)_2(s)+6KCl(aq.)

By Stoichiometry of the reaction:

2 moles of aqueous solution of potassium phosphate reacts with 3 moles of aqueous solution of magnesium chloride to produce 1 mole of solid magnesium phosphate and 6 moles of aqueous solution of potassium chloride.

Hence, the other product formed is potassium chloride.

What is the mass of 3.2 moles of Sulfur?​
FinnZ [79.3K]

Answer:

820.864 g

Explanation:

1) The atomic mass of sulfur (found from the periodic table) is 32.065 amu. Use this mass to find the molar mass of Sulfur. Sulfur is S8 so the molar mass of sulfur is:

8 × 32.065 = 256.52 g/mol

2) To find the mass use the formula:

m = n × M where <em>m</em><em> </em>is the mass, <em>n</em><em> </em>is the number of moles, and <em>M</em><em> </em>is the molar mass.

3)

m \: = 3.2 \times 256.52

m = 820.864 \: g

Calculate the molecular masses of C4 H10 atoms molecules or ionic formulae​
Basile [38]
C4H10 is an alkane (propane to be precise)

The relative formula mass of a molecule of propane is

(12x4) + (1x10) = 58

because a carbon atom has an atomic weight of 12 and a hydrogen atom has an atomic weight of 1.
