How many liters of. 225 M Na2S solution would be required to react completely with 81. 8 g Fe(C2H3O2)3? (The molar mass of iron (III) acetate is 233. 00 g/mol. )

Answers

Answer 1

0.002 liters of 225 M Na2S solution is required to completely react with 81.8 g Fe(C2H3O2)3

Starting from the balanced equation of the reaction and the molar mass of iron (III) acetate (Fe(C2H3O2)3, first the reacting moles of this compound are determined, then the amount of reacting moles of sodium sulfide (Na2S) is determined and finally the amount of solution that contains said amount of moles.

Balanced equation of the reaction

3Na2S + 2Fe(C2H3O2)3 → 6NaC2H3O2 + Fe2S3

Determination of liters of 225 M Na2S solution for a complete reaction

This determination is made in three steps:

Determination of reactant moles of Fe(C2H3O2)3Determination of the reactant moles of Na2SDetermination of the volume of solution with the number of reacting moles of Na2S

Determination of reactant moles of Fe(C2H3O2)3

If 233.00 g of Fe(C2H3O2)3 is equivalent to 1 mol of Fe(C2H3O2)3

So 81. 8 g Fe(C2H3O2)3 equals x mol of Fe(C2H3O2)3

X mol of Fe(C2H3O2)3 = 81. 8 g Fe(C2H3O2)3 x 1 mol of Fe(C2H3O2)3 / 233.00 g of Fe(C2H3O2)3

X mol of Fe(C2H3O2)3 = 0.351 mol

Determination of the reactant moles of Na2S

If 2 moles of Fe(C2H3O2)3 react with 3 moles of Na2S

Then 0.351 mol of Fe(C2H3O2)3 reacts with x mol of Na2S

X mol of Na2S = 0.351 mol Fe(C2H3O2)3 x 3 mol of Na2S / 2 mol of Fe(C2H3O2)3 = 0.526 mol

Determination of the volume of solution with the number of reacting moles of Na2S

If there are 225 moles of Na2S in 1 liter of solution

So there are 0.526 moles of Na2S in x liter of solution.

X liter of solution = 0.526 mol of Na2S x 1 liter of solution / 225 mol of Na2S = 0.0023 liters, that is, 2.3 ml

Therefore, 0.0023 liters of 225M Na2S solution is required.

Answers

Almost all of the oxygen (O2) one consumes in breathing is converted to: b. carbon dioxide (CO2).

When we breathe in oxygen, it is used in cellular respiration, which is the process by which our body converts glucose and oxygen into energy in the form of ATP. In the process, the oxygen is combined with the hydrogen atoms from glucose to form water, and the carbon atoms from glucose are converted to carbon dioxide (CO2) as a waste product. Therefore, almost all of the oxygen that one consumes in breathing is converted to carbon dioxide (CO2).Breathing is the process by which an organism takes in oxygen and expels carbon dioxide. In humans and other mammals, this process is accomplished through the respiratory system, which includes the nose, trachea, bronchi, and lungs.

an unbalanced 16.0 N force is applied to a 2.0 kg mass. what is the acceleration of the mass

Answers

The acceleration of the mass is 8.0 m/s² when an unbalanced 16.0 N force is applied to a 2.0 kg mass.

To calculate the acceleration of the mass, we can use Newton's second law of motion, which states that the force acting on an object is equal to the mass of the object multiplied by its acceleration (F = ma).

We know that the force acting on the object is 16.0 N, and the mass of the object is 2.0 kg. So, we can use the equation to solve for the acceleration:

a = F ÷ m

where, a = acceleration, F = force (16.0 N), m = mass (2.0 kg)

So,

a = 16.0 N ÷ 2.0 kg = 8.0 m/s²

Therefore, the acceleration of the mass is 8.0 m/s²

O The United States should specialize in cheese and trade it for tomatoes from Italy.

Answers

On this scenario, the US may consume more than its PPC by specializing in cheese and swapping it for Italian tomatoes.

What makes this possible?

Italy’s cheese output is lower than that of the United States.Italy cannot consume cheese other than PPC unless these products are supplied by another nation. Through an exchange deal with Italy, the United States can enjoy tomatoes in addition to PPC. Because cheese production in the United States is substantially higher than in Italy, we may assume that the United States can offer this commodity to other nations without jeopardizing its consumption. However, tomato output in the United States is the same as in Italy, but because the United States is a larger country than Italy, tomato consumption in the country may be affected.

As a result, if tomatoes are obtained from another nation, tomato consumption in the United States may surpass the PPC of tomatoes. This may be accomplished through barter, with the United States supplying cheese to Italy and Italy supplying tomatoes to the United States.

Analysis of a 10.150 grams sample of a compound known to contain only phosphorus and oxygen indicates a phosphorus content of 4.433 grams. What is the empirical formula of this compound

Answers

A 10.150 grams sample of a compound containing only phosphorus and oxygen which indicates a phosphorus content of 4.433 grams has the empirical formula P₂O₅.

An Empirical formula is defined as the simplest whole number ratio of different atoms present in the molecule of a compound.

given,

mass of the unknown compound= 10.150 g

mass of phosphorus= 4.433 g

therefore, mass of oxygen

=mass of the unknown compound -  mass of phosphorus

=10.150-4.433 g

=5.717 g

we know that

molar mass of oxygen = 16 g/mol

molar mass of phosphorus = 31 g/mol

number of moles of oxygen

=mass/molar mass

=5.717g/16gmol⁻¹

=0.357

number of moles of phosphorus

= mass/molar mass

= 4.433g/31gmol⁻¹

=0.143

Now, we will divide the moles by the smallest number of moles (0.143)

O= 0.357 / 0.143 =2.49≈ 2.5

P= 0.143 /0.143 = 1

now, we will multiply both numbers by 2 to get the simplest whole number ratio

O= 2.5×2= 5

P= 1×2= 2

Thus, the empirical formula is P₂O₅.

Answers

3.88 grams of sodium azide are required to form 5.00 g of nitrogen gas.

In order to determine how many grams of sodium azide are required to form 5.00 g of nitrogen gas, we can use the balanced equation for the reaction:

2NaN3 (s) → 2Na (s) + 3N2 (g)

We can start by converting the given amount of nitrogen gas to moles:

5.00 g N2 x (1 mol N2 / 28.00 g N2) = 0.1786 mol N2

We know that the reaction produces 3 moles of N2 for every 2 moles of NaN3 that are used, so we can use the following ratio to find the number of moles of NaN3 required:

0.1786 mol N2 / 3 mol N2 = 0.0596 mol NaN3

Finally, we can convert moles of NaN3 back to grams using the molar mass of NaN3:

0.0596 mol NaN3 x (64.99 g NaN3 / 1 mol NaN3) = 3.88 g NaN3

So, 3.88 grams of sodium azide are required to form 5.00 g of nitrogen gas.
