C,H,O,+ 3HCI → C,HCl, + 3H20<br> right 5 possible mole ratios

Marina86 [1]

Answer:

Here's what I get

Explanation:

I think this may be the equation you intended to write:

C₃H₅(OH)₃ + 3HCl ⟶ C₃H₅Cl₃ + 3H₂O

The mole ratios are the ratios of the coefficients in the balanced equation.

Here are some of the possible molar ratios.

C₃H₅(OH)₃:HCl = 1:3
C₃H₅(OH)₃:C₃H₅Cl₃ = 1:1
C₃H₅(OH)₃:H₂O = 1:3
HCl:C₃H₅Cl₃ = 3:1
HCl:H₂O = 3:3
C₃H₅Cl₃:H₂O = 1:3

The reaction of NH3 and O2 forms NO and water. The NO can be used to convert P4 to P4O6, forming N2 in the process. The P4O6 can

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.

how many grams of water can be produced when 65.5 grams of sodium hydroxide react with excess sulfuric acid.

34kurt

2NaOH+H2SO4--> Na2SO4+2H2O

80g NaOH(40g/mol)--> 36g H2O (18g/mol)

65.5 x (1/40g/mol)= 1.64 moles of NaOH

1.64 x 18g/mol= 29.5 g H2O
