calculate the theoretical yield (in grams) of the solid product if 1.0 gram of fec2o4∙2h2o is reacted completely in excess oxygen gas. fec2o4∙2h2o (s) → feco3(s) 2 h2o(g) co(g)

Answers

Answer 1

The theoretical yield of the solid product (FeCO3) is 0.463 grams for excess oxygen gas.

We must first balance the chemical equation in order to compute the theoretical yield of the solid product:

2H2O(s) + 3O2(g) FeC2O4(s) + 2H2O(g) + 2CO(g)

We can see from the balanced equation that 1 mole of FeC2O4H2O produces 1 mole of FeCO3.

FeC2O4H2O has the following molar mass:

FeC2O4H2O = (1 x Fe atomic mass) + (2 x C atomic mass) + (4 x O atomic mass) + (2 x H atomic mass) + (2 x O atomic mass) = 55.85 + 2(12.01) + 4(16.00) + 2(1.01) + 2(16.00) = 249.86 g/mol

As a result, 1.0 g of FeC2O4H2O is comparable to:

0.004 mol = 1.0 g / 249.86 g/mol

Because one mole of FeC2O42H2O yields one mole of FeCO3, the theoretical yield of FeCO3 is also 0.004 mol.

FeCO3 has the following molar mass:

FeCO3 has the following molar mass:

FeCO3 = Fe atomic mass + C atomic mass + 3(O atomic mass) = 55.85 + 12.01 + 3(16.00) = 115.86 g/mol

As a result, the theoretical yield of FeCO3 is:

0.463 g = 0.004 mol x 115.86 g/mol

Answer 2

   

The theoretical yield of FeCO3 is 0.618 grams.

To calculate the theoretical yield of FeCO3, we first need to balance the equation to determine the mole ratio between FeC2O4∙2H2O and FeCO3. The balanced equation is:

 FEC2O4∙2H2O (s) + 1.5O2 (g) → FeCO3(s) + 2H2O (g) + CO (g)

From the equation, we can see that 1 mole of FEC2O4∙2H2O will produce 1 mole of FeCO3. The molar mass of FEC2O4∙2H2O is 179.91 g/mol. Therefore, 1.0 g of FEC2O4∙2H2O is equal to 0.00556 moles. Since the mole ratio of FEC2O4∙2H2O to FeCO3 is 1:1, the theoretical yield of FeCO3 is also 0.00556 moles. The molar mass of FeCO3 is 115.86 g/mol. Thus, the theoretical yield of FeCO3 is 0.618 grams.

Nucleophilic acyl substitution reaction is the mechanism for the formation of triphenylmethanol from the reaction of phenylmagnesium bromide and diethyl carbonate.

Phenyl magnesium bromide substitutes one ethoxide ion in the nucleophilic acyl substitution reaction that drives the process forward. A subsequent equivalent of phenyl magnesium bromide produces triphenyl methanol through a nucleophilic addition reaction with the resultant keto group.

There are two ethoxy leaving groups in diethyl carbonate. Tertiary alcohol is created when diethyl carbonate combines with too much Grignard reagent. The Grignard reagent attacks the carbonyl carbon three times in the mechanism to produce the tertiary alcohol.

4- The equilibrium constant for the reaction A (g) B (g) is 10. A reaction mixture initially contains [A]

Answers

The initial concentration in the reaction mixture will contain [A] = 0.1 M and [B] = 1.0 M

Below is the reaction

A(g) → B(g)

And the equilibium constant will be explained in terms of [A] and [B]:

Keq = 10 = [B]/[A]

If the first conditions are that [A] = 1.1 M and [B] = 0.0 M, the conditions at equilibrium is:

[A] = 1.1M - x

[B] = 0.0M + x

Now we rewrite Keq:

Keq = 10 = [0.0 +x] / [1.1 -x]

at the end we got it  for x:

10 = [0.0 +x] / [1.1 -x]

10 * (1.1-x) = x

11 - 10x = x

11 = 11x

x = 1

equilibrium, the concentrations are:

[A] = 1.1 M - 1 = 0.1 M

[B] = 0.0 M + 1 = 1.0 M

Thus, the concentration of A is 0.1 M and the concentration of B is 1M.

Answers

The osmotic pressure of a solution made from 12.5 g of CaCl2 in enough water to make 500 mL, if CaCl2 is 78.5% dissociated at 30oC is 167.087 atm

Define osmotic pressure:-

Osmotic pressure and osmosis are connected. Osmosis is the passage of a solvent through a semipermeable membrane into a solution. The pressure that halts the osmosis process is known as osmotic pressure. Osmotic pressure is a collective attribute of material because its value is determined by the solute's concentration rather than its chemical composition.

The formula used to calculate Osmotic Pressure is:-

π = M x R x T x i

Where;

π =osmotic pressure (in atm)

M=molar concentration (in mol/L)

  =(given mass/molar mass)/volume=(12.5g /111.0)/(500/1000)

  =0.224 mol/L

R=Universal gas constant (0.08206 L.atm/mol.K)

T=absolute temperature (in K) = 30.C + 273 = 303 K

i= van't Hoff factor of solute =3

using the formula and  substituting values;

Both processes are natural, but they can also be carried out in a lab. While fusion involves the "crushing" of two atoms to form a single atom of a new element, fission involves the splitting of an atomic nucleus.

We can conclude from this information that radioactive waste from fusion reactions becomes less hazardous much sooner than waste from fission reactions, and nuclear fusion is much safer than fission because it produces no radioactive waste.
