If 0.332 mol of zinc reacts with excess lead(IV) sulfate, how many grams of zinc sulfate will be produced in the reaction?

Answers

Answer 1

Answer:

53.6 g

Explanation:

Step 1: Write the balanced equation

2 Zn + Pb(SO₄)₂ ⇒ 2 ZnSO₄ + Pb

Step 2: Calculate the moles of ZnSO₄ produced from 0.332 moles of Zn

The molar ratio of Zn to ZnSO₄ is 2:2. The moles of ZnSO₄ produced are 2/2 × 0.0332 mol = 0.0332 mol.

Step 3: Calculate the mass corresponding to 0.332 moles of ZnSO₄

The molar mass of ZnSO₄ is 161.44 g/mol.

0.332 mol × 161.44 g/mol = 53.6 g

An example of a chemical reaction

In a chemical reaction, reactants undergo a chemical reaction and transform into products through a chemical process. For instance, when humans breathe in oxygen, it combines with glucose to create carbon dioxide, water, and energy.

The temperature is 273.15 K and the pressure is 1 atm at STP (standard temperature and pressure).

The ideal gas law can be rearranged to account for V:

V = (nRT) / P

Substituting the values we are aware of:

n = 138 mol

R = 0.0821 L·atm/(mol·K)

T = 273.15 K

P = 1 atm

V = (138 mol * 0.0821 L·atm/(mol·K) * 273.15 K) / 1 atm

V = 3,092.1 L

How many particles are in 1.43 g of a compound with a molar mass of 233? (No molar mass calculation needed) (show work plz)

Answers

Answer:

Explanation:

mol = given mols / molar mass

given mass = 1.43 grams

molar mass = 233

mols = 1.43 / 233 = 0.00614

1 mol contains 6.02 * 10^23 particles

0.00614 moles = x                                  Cross multiply

1*x = 0.00614 * 6.02*10^23

x = 3,68 * 10^21 particles.

n a volumetric analysis experiment, a solution of sodium oxalate (Na 2C 2O 4) in acidic solution is titrated with a solution of potassium permanganate (KMnO 4) according to the following balanced chemical equation: 2KMnO4(aq) + 8H2SO4(aq) + 5Na2C2O4(aq) → 2MnSO4(aq) + 8H2O(l) + 10CO2(g) + 5Na2SO4(aq) + K2SO4(aq) It required 40.0 mL of 0.0335 M KMnO4 to reach the endpoint. What mass of Na2C2O4 was present initially?

Answers

Answer:

mNa₂C₂O₄ = 0.4489 g

Explanation:

This is a problem of stechiometry. in this case, we need to find the mole ratio between the permanganate solution and the oxalate. This can be seen in the balanced reaction which is the following:

2KMnO₄ + 8H₂SO₄ + 5Na₂C₂O₄---> 2MnSO₄ + 8H₂O + 10CO₂ + 5Na₂SO₄ + K₂SO₄

According to this balanced reaction, we have a mole ratio of 2:5 between permanganate and oxalate, so, the first thing to do here is calculate the moles of the permanganate needed to reach the endpoint of this titration:

n = M * V

Replacing we have:

nKMnO₄ = 0.0335 mol/L  * 0.040 L = 0.00134 moles

With these moles, and the above mole ratio, we can determine the moles of the oxalate:

2 moles KMnO₄ -------> 5 moles Na₂C₂O₄

0.00134 moles ---------> X

X = 0.00134 * 5 / 2

nNa₂C₂O₄ = 0.00335 moles

Finally, with the molecular mass of Na₂C₂O₄, we can determine the mass of the oxalate:

Molecular weights:

Na: 23 g/mol;   C: 12 g/mol;    O: 16 g/mol

MMNa₂C₂O₄ = (23*2) + (2*12) + (4*16) = 134 g/mol

mNa₂C₂O₄ = nNa₂C₂O₄ * MM

mNa₂C₂O₄ = 0.00335 * 134

mNa₂C₂O₄ = 0.4489 g

a phosphorus ion with a charge of -2 has ____ protons ____ neutrons,and _____ electrons

Answers

The number of protons of an atom is always equal to the atomic number of the atom's element. In this case, we can assume that a phosphorus ion is simply an atom of phosphorus that is an ion, i.e., an atom with a nonzero electric charge. To refresh, there are three key subatomic particles that make up an atom: protons (which have a positive charge), neutrons (which have no electric charge), and electrons (which have a negative charge). Protons and neutrons are found bound to each other in the nucleus (an exception would be a neutral hydrogen, ¹H, atom, whose nucleus comprises only a single proton and no neutrons).

The atomic number of phosphorus is 15. Therefore, the phosphorus ion has 15 protons.

The number of neutrons in a phosphorus atom can be calculated by subtracting the atomic number from the atomic weight. The atomic weight of phosphorus is approximately 30.974 amu (the decimals come from the fact that this value is a weighted average of the masses of naturally-occurring isotopes of phosphorus). For our purposes, we can round our atomic weight to 31, which would reflect the number of protons and neutrons in a phosphorus atom. Subtracting our 15 protons from 31 gives us 16 neutrons. Since neutrons have no electric charge, their number would be the same in both a neutral atom and an ion of a particular isotope of phosphorus. Since we're presumably working with ³¹P (which is by far the most abundant isotope), we can safely say that the phosphorus ion has 16 neutrons.

Recall that protons have a positive charge, and we've just reiterated that neutrons have no electric charge. If all that made up an atom were protons and neutrons, the atom would have a net positive charge due to the protons. A neutral atom of an element, by definition, has no net charge because of the negatively-charged electrons surrounding the positively-charged nucleus. It follows, then, that in a neutral atom, the number of electrons equals the number of protons; so, in a neutral phosphorus atom, there would be 15 protons, 16 neutrons, and 15 electrons. The 15 positively-charged protons would neutralize the 15 negatively-charged electrons, resulting in a net atomic charge of 0.

In our phosphorus ion, we have a net charge of -2. That means that, given a nucleus with 15 positively-charged protons, we have an imbalance of 2 more negative charges. 15 electrons are needed to maintain an electrically neutral phosphorus atom; for each electron that is removed, the atom gains a positive charge, and for each electron that is added, the atom gains a negative charge. Since we have a -2 charge in the phosphorus ion, there must be 2 electrons in addition to the 15 electrons found in a neutral phosphorus atom, or 17 electrons in total. Therefore, the phosphorus ion has 17 electrons.

Note: A positively-charged ion is also called a cation, and a negatively charged ion is also called an anion. The charge of an ion has the general form Xⁿ⁺ or Xⁿ⁻, where X is the chemical species (such as an element), n is the magnitude of the charge, and the + or - respective denote a net positive or negative charge. In this case, one could represent the phosphorus anion as P²⁻.

A phosphorus ion with a charge of -2 has 15 protons, 16 neutrons, and 18 electrons.

The atomic number of phosphorus is 15, which means it naturally has 15 protons in its nucleus. Since the ion has a charge of -2, it means it has gained two extra electrons.

The number of protons remains the same in an ion, so it still has 15 protons. However, the number of electrons changes to accommodate the charge. The ion possesses 15 protons and 17 electrons because it has a -2 charge.

To calculate neutrons, subtract 15 from phosphorous' mass number. The neutron count for phosphorus is 31 - 15 = 16. Thus, a -2 phosphorus ion contains 15 protons, 16 neutrons, and 18 electrons.

ASAP!! How many moles are in 125 g of H2SO4

Answers

Answer:

1.276 moles

Explanation:

molar mass of H2SO4 = 2(1)+(32)+4(16) = 98 g

So, there are (125g)(1 mol/98g) = 1.276 moles

1.276 moles are in 125 g of H[tex]_2[/tex]SO[tex]_4[/tex]. A mole is indeed a unit that enables us to correlate the mass of a material with its components.

What is mole?

It is defined as the amount of any material that has the same number of basic units as there are in a precisely measured sample of 12C that weighs 12 g. Latin's word for pile, stack, or assemblage is "mole." The number of entities that make up a mole was discovered via experimentation to be 6.022 X 1023.

A mole is indeed a unit that enables us to correlate the mass of a material with its components. The total of the masses of all the atoms that make up one mole of a molecule, expressed in grams, is what is known also as molecular mass or molar mass. A substance's molar mass may be calculated by multiplying its given mass by its g/mol density.

molar mass of H[tex]_2[/tex]SO[tex]_4[/tex] = 2(1)+(32)+4(16)

                                    = 98 g

mole= (125g)(1 mol/98g)

       = 1.276 moles

Therefore, 1.276 moles are in 125 g of H[tex]_2[/tex]SO[tex]_4[/tex].

WS Percent yield don’t understand how to do would appreciate the help

Answers

Answer:

1. Theoretical yield of NaOH is 22.72 g

2. Percentage yield of NaOH = 22.14%

Explanation:

We'll begin by writing the balanced equation for the reaction. This is illustrated below:

NaHCO₃ —> NaOH + CO₂

From the balanced equation above,,

1 mole of NaHCO₃ decomposed to produce 1 mole (i.e 40 g) of NaOH and 1 mole (i.e 44.01 g) of CO₂.

Next, we shall determine the number of mole of NaHCO₃ that will decompose to produce 25 g of CO₂. This can be obtained as follow:

From the balanced equation above,,

1 mole of NaHCO₃ decomposed to produce 44.01 g of CO₂.

Therefore, Xmol of NaHCO₃ will decompose to 25 g of CO₂ i.e

Xmol of NaHCO₃ = 25 / 44.01

Xmol of NaHCO₃ = 0.568 mole

1. Determination of the theoretical yield of NaOH.

From the balanced equation above,,

1 mole of NaHCO₃ decomposed to produce 40 g of NaOH.

Therefore, 0.568 mole of NaHCO₃ will decompose to produce = 0.568 × 40 = 22.72 g of NaOH.

Thus, the theoretical yield of NaOH is 22.72 g

2. Determination of the percentage yield of NaOH.

Theoretical yield of NaOH = 22.72 g

Actual yield of NaOH = 5.03 g

Percentage yield of NaOH =?

Percentage yield = Actual yield /Theoretical yield × 100

Percentage yield = 5.03 / 22.72 × 100

Percentage yield of NaOH = 22.14%
