Answer : The mass of $PH_3$ produced from the reaction is, 0.651 grams.

Explanation :

The chemical reactions used are:

(1) $4NH_3+5O_2\rightarrow 4NO+6H_2O$

(2) $6NO+P_4\rightarrow P_4O_6+3N_2$

(3) $P_4O_6+6H_2O\rightarrow 4H_3PO_4$

(4) $4H_3PO_4\rightarrow PH_3+3H_3PO_4$

First we have to calculate the moles of $NH_3$

$\text{Moles of }NH_3=\frac{\text{Mass of }NH_3}{\text{Molar mass of }NH_3}$

Molar mass of $NH_3$ = 17 g/mol

$\text{Moles of }NH_3=\frac{1.95g}{17g/mol}=0.115mol$

Now we have to calculate the moles of $NO$

From the balanced chemical reaction 1, we conclude that:

As, 4 moles of $NH_3$ react to give 4 moles of $NO$

So, 0.115 moles of $NH_3$ react to give 0.115 moles of $NO$

Now we have to calculate the moles of $P_4O_6$

From the balanced chemical reaction 2, we conclude that:

As, 6 moles of $NO$ react to give 1 moles of $P_4O_6$

So, 0.115 moles of $NO$ react to give $\frac{0.115}{6}=0.0192$ moles of $P_4O_6$

Now we have to calculate the moles of $H_3PO_4$

From the balanced chemical reaction 3, we conclude that:

As, 1 moles of $P_4O_6$ react to give 4 moles of $H_3PO_4$

So, 0.0192 moles of $P_4O_6$ react to give $0.0192\times 4=0.0768$ moles of $H_3PO_4$

Now we have to calculate the moles of $PH_3$

From the balanced chemical reaction 4, we conclude that:

As, 4 moles of $H_3PO_4$ react to give 1 moles of $PH_3$

So, 0.0768 moles of $H_3PO_4$ react to give $\frac{0.0768}{4}=0.0192$ moles of $PH_3$

Now we have to calculate the mass of $PH_3$

$\text{ Mass of }PH_3=\text{ Moles of }PH_3\times \text{ Molar mass of }PH_3$

Molar mass of $PH_3$ = 33.9 g/mole

$\text{ Mass of }PH_3=(0.0192moles)\times (33.9g/mole)=0.651g$

Therefore, the mass of $PH_3$ produced from the reaction is, 0.651 grams.

Why is7/2 ther in this equation and what can i do to make it a whole no? C3H8+7/2O2→3CO+4H2OC3H8+72O2→3CO+4H2O

ExtremeBDS [4]

You can Multiply the whole equation with 2 as it is the denomanot number of 7/2.Therefore,the denomanator will be canceled out with 2 and the number of 7/2 will become 7.
Steps by Steps solution:
C3H8+7/2O2→3CO+4H2OC3H8+72O2→3CO+4H2O
=2×(C3H8+7/2O2→3CO+4H2OC3H8+72O2→3CO+4H2O)
=2C3H8+7O2→6CO+8H2OC3H8+144O2→6CO+8H2O

Which set of chemical name and chemical formula for the same compound is correct?A. Ammonium sulfite, (NH4)2SB. Iron(III) Phosph

gregori [183]

Answer : The correct option is, Iron(III) phosphate, $FePO_4$ .

Explanation :

Ionic compound : It is defined as the compound which is formed when electron gets transferred from one atom to another atom.

All the polyatomic ions always form an ionic compound.

Polyatomic ions : It is a charged species that composed of two or more atoms and these charged species are bonded by the covalent bond.

(1) The chemical formula for Ammonium sulfite.

The given compound ammonium sulfate is an ionic compound. It is made up of two different ions which are ammonium ion $(NH_4^+)$ and sulfite ion $(SO_3^{2-})$ by the criss-cross method. Thus, the correct chemical formula for ammonium sulfite is $(NH_4)_2SO_3$ .

(2) The chemical formula for Iron(III) phosphate.

The given compound iron(III) phosphate is an ionic compound. It is made up of two different ions which are iron ion $(Fe^{3+})$ and phosphate ion $(PO_4^{3-})$ by the criss-cross method. Thus, the correct chemical formula for iron(III) phosphate is $FePO_4$ .

(3) The chemical formula for Lithium carbonate.

The given compound lithium carbonate is an ionic compound. It is made up of two different ions which are lithium ion $(Li^+)$ and carbonate ion $(CO_3^{2-})$ by the criss-cross method. Thus, the correct chemical formula for lithium carbonate is $Li_2CO_3$ .

(4) The chemical formula for Magnesium dichromate.

The given compound magnesium dichromate is an ionic compound. It is made up of two different ions which are magnesium ion $(Mg^{2+})$ and dichromate ion $(Cr_2O_7^{2-})$ by the criss-cross method. Thus, the correct chemical formula for magnesium dichromate is $MgCr_2O_7$ .

From this we conclude that, the correct set of chemical name and chemical formula for the same compound is Iron(III) phosphate.

Hence, the correct option is, Iron(III) phosphate, $FePO_4$ .
