Calculate the maximum numbers of moles and grams of iodic acid (HIO₃) that can form when 635 g of iodine trichloride reacts with
poizon [28]

What is Chemical Reaction?

A chemical reaction occurs when a certain group of molecules converts into another form without affecting their nuclei; only the transfer or sharing of electrons and the building and breaking of bonds occur.

Main Content

Known :

\mathrm{ICl}_{3}+\mathrm{H}_{2} \mathrm{O} \longrightarrow \mathrm{ICl}+\mathrm{HIO}_{3}+\mathrm{HCl}

Mass of ICI_3 = 635g

Mass of H_2O = 118.5g

Calculations :

First, balance the given chemical equation by place 2,3 and 5 as the coefficients of ICI_3, H_2O and HCl,\\ Respectively

2 \mathrm{ICl}_{3}+3 \mathrm{H}_{2} \mathrm{O} \longrightarrow \mathrm{ICl}+\mathrm{HIO}_{3}+5 \mathrm{HCl}

We multiply the given mass of ICl_3 by the reciprocal of its molar mass to get the number of moles. The molar mass of ICl_3 is 233.26g/mol

\text { Moles of } \mathrm{ICl}_{3}=635 \mathrm{~g} \mathrm{ICl}_{3} \times \frac{1 \mathrm{~mol} \mathrm{ICl}_{3}}{233.26 \mathrm{~g} \mathrm{ICl}_{3}}=2.7223 \mathrm{~mol}  \mathrm{ICl}_{3}

Them, we multiply the ratio between ICl_3 and HIO_3. based on the chemical equation, the molar ratio 1 mol HIO_3/2  mol ICl_3.

\text { Moles of } \mathrm{HIO}_{3} \text { formed }=2.7223 \mathrm{~mol} \mathrm{ICl}_{3} \times \frac{1 \mathrm{~mol} \mathrm{HIO}_{3}}{2 \mathrm{~mol} \mathrm{ICl}_{3}}=1.3612 \mathrm{~mol} \mathrm{HIO}_{3}

For water, we again multiply the given mass H_2O by the reciprocal of its molar mass to get the number if moles. The molar mass of H_2O is 18.02g/mol

\text { Moles of } \mathrm{H}_{2} \mathrm{O}=118.5 \mathrm{~g} \mathrm{H}_{2} \mathrm{O} \times \frac{1 \mathrm{~mol} \mathrm{H}_{2} \mathrm{O}}{18.02 \mathrm{~g} \mathrm{H}_{2} \mathrm{O}}=6.5760 \mathrm{~mol} \mathrm{H}_{2} \mathrm{O}

Then, we multiply the molar ratio between H2O and HIOs. Based on the chemical equation, the molar ratio is 1 mol HIO_3/3 Mole H_2O

\text { Moles of } \mathrm{HIO}_{3} \text { formed }=6.5760 \mathrm{~mol} \mathrm{H}_{2} \mathrm{O} \times \frac{1 \mathrm{~mol} \mathrm{HIO}_{3}}{3 \mathrm{~mol} \mathrm{H}_{2} \mathrm{O}}=2.1920 \mathrm{~mol} \mathrm{HIO}_{3}

We can see that the limiting reactant is ICL_3 since the given mass of ICl_3 forms lesser product than water does. Thus , the maximum number of moles of HIO_3 formed is 1.36 mol HIO_3. We now multiply the molar mas of HIO_3 to the calculated number of moles. The molar mass of HIO_3 is 175.91 g/mol.

Mass of HIO_3 formed (Max) =1.3612 \mathrm{~mol} \mathrm{HIO}_{3} \times \frac{175.91 \mathrm{~g} \mathrm{HIO}_{3}}{1 \mathrm{~mol} \mathrm{HIO}}=239 \mathrm{~g} \mathrm{HIO}_{3}

We multiply the number of moles of ICl_3 by the molar ratio between ICl_3 and H_2O which is 3 mol H_2O mol ICl_3 we get the number of moles of H_2O reacted. Then, we multiply the molar mass of water.

Mass of H_2O reacted =2.7223 \mathrm{~mol} \mathrm{ICl} 3 \times \frac{3 \mathrm{~mol} \mathrm{H}_{2} \mathrm{O}}{2 \mathrm{~mol} \mathrm{ICl}_{3}} \times \frac{18.02 \mathrm{~g} \mathrm{H}_{2} \mathrm{O}}{1 \mathrm{~mol} \mathrm{H}_{2} \mathrm{O}}

Mass of H_2O reacted = 73.6g H_2O

We subtract the mass of H_2O reacted from the given mass of H_2O.

Mass of H_2O = 118.5 - 73.6g = 44.9g H_2O

How does the concentration of ions in a strong acid differ from a weak acid?
Mkey [24]

Answer:

A strong base has a much smaller concentration of positive ions (hydrogen ions) and a much greater concentration of negative ions (hydroxide ions). The weak base has a much greater concentration of positive ions (hydrogen ions) and a much smaller concentration of negative ions ( hydroxide ions) = answer !!

How many moles of water are represented by 8.33×10^18 molecules of water​
DENIUS [597]

Answer:

number of moles of water (n) = 1.383 x10 ⁻⁵ mol

Explanation:

Data Given:

No. of molecules of water =  8.33×10¹⁸

No. of Mole of water = ?

Formula Used to calculate

no. of moles = numbers of particles (ions, molecules, atoms) /Avogadro's number

Avogadro's no. = 6.023 x10²³

So the formula could be written as

                no. of moles (n) = no. of molecules of water /6.023 x10²³

Put the values in above formula

                 no. of moles (n) = 8.33×10¹⁸ /6.023 x10²³

                  no. of moles (n) = 8.33×10¹⁸ /6.023 x10²³

                  no. of moles (n) = 1.383 x10 ⁻⁵

so  1.383 x10 ⁻⁵ moles of water are represented by  8.33×10¹⁸ molecules of water.

The heat of vaporization for benzaldehyde is 48.8 kj/mol, and its normal boiling point is 451.0 k. use this information to deter
user100 [1]

Answer:

The vapor pressure of benzaldehyde at 61.5 °C is 70691.73 torr.

Explanation:

  • To solve this problem, we use Clausius Clapeyron equation: ln(P₁/P₂) = (ΔHvap / R) (1/T₁ - 1/T₂).
  • The first case: P₁ = 1 atm = 760 torr and T₁ = 451.0 K.
  • The second case: P₂ = <em>??? needed to be calculated</em> and T₂ = 61.5 °C = 334.5 K.
  • ΔHvap = 48.8 KJ/mole = 48.8 x 10³ J/mole and R = 8.314 J/mole.K.
  • Now, ln(P₁/P₂) = (ΔHvap / R) (1/T₁ - 1/T₂)
  • ln(760 torr /P₂) = (48.8 x 10³ J/mole / 8.314 J/mole.K) (1/451 K - 1/334.5 K)
  • ln(760 torr /P₂) = (5869.62) (-7.722 x 10⁻⁴) = -4.53.
  • (760 torr /P₂) = 0.01075
  • Then, P₂ = (760 torr) / (0.01075) = 70691.73 torr.

So, The vapor pressure of benzaldehyde at 61.5 °C is 70691.73 torr.
