Ammonium phosphate NH43PO4 is an important ingredient in many fertilizers. It can be made by reacting phosphoric acid H3PO4 with

mestny [16]

Answer:

The weight of ammonium phosphate is 10 gm

Explanation:

The chemical reaction of ammonium phosphate formation is as follows.

$3NH_{3}+H_{3}PO_{4} \rightarrow [(NH_{4})_{3}PO_{4}]$

From the reaction one mole of phosphoric acid is equivalent to the one mole of ammonium phosphate.

So, "n" mole of phosphoric acid is equivalent to the "n" mole of ammonium phosphate.

Number of moles in 7.1 grams of phosphoric acid = $\frac{7.1}{Molarmass\,of phosphoric\,acid}$

$\frac{7.1}{98}= \frac{1}{13.8}$

<u>Formation weight of ammonium phosphate :</u>

Weight of ammonium phosphate = $= \frac{1}{13.8}\times Molarmass\,of\,\,ammonium\,phosphate$

$=\frac{149}{13.8} = 10.79gm$

Round the answer to 2 significant digits

Weight of ammonium phosphate = 10 gm

What does two bonded flurione atoms form?

Archy [21]

2 Fluorine atoms covalently bonded with each other, each sharing an equal number of a single, one valence electron to achieve a stable octet, would form a diatonic fluorine gas. It is a diatomic molecule, a molecule consisting of 2 atoms that are the same, in this case fluorine.

In a thin layer chromatography experiment, a plate of length 9.3 cm was used and a horizontal line was made at 1.45 cm above the

dezoksy [38]

Answer: The $R_f$ value is 0.664

Explanation:

Distance travelled by solvent front = (7.7-1.45)cm = 6.25 cm

Distance travelled by unknown = (5.6-1.45) cm = 4.15 cm

The retention factor or the $R_f$ value is defined as the ratio of distance traveled by the unknown to the distance traveled by the solvent front.

$R_f=\frac{\text {distance travelled by unknown}}{\text {distance travelled by solvent}}$

$R_f=\frac{4.15}{6.25}=0.664$

Thus the $R_f$ value is 0.664
