What mass of MnCl2 is produced when 0.091 g of Cl2 is generated?

Answers

Answer 1
MMn = 54.94g/mol
MO2 = 2(16) = 32g/mol
MH = 1g/mol
MCl = 35.45g/mol
Molar Mass of MnO2:
54.94
+
2
(
16
)
=
86.94
Molar Mass of HCl:
1
+
35.45
=
36.45
Looking at the equation, we need a 4:1 ratio of HCl to MnO2 to make the reaction work, let's see if we have four times as much of the HCl.
Mols of MnO2:
42.7
86.94
=
0.49
Mols of HCl:
47.1
36.45
=
1.29
As we can see, we have less than the amount of HCl we need for all of the MnO2 to react, therefore the HCl is the limiting reactant.
For the theoretical yield of Cl2, we need to determine how many mols will be produced. As we can see by the equation, four mols of HCl make one mol of Cl2.
Molar Mass of Cl2:
35.45

2
=
70.9
Since we have 1.29mol of HCl, and we know it is the limiting reactant:
Mols of Cl2
1.29
4
=
0.323
Mass of Cl2 (Theoretical yield)
0.323

70.9
=
22.9
To calculate the actual yield, we multiply the theoretical yield by the final percentage:
22.9

0.791
=
18.11
Therefore, the actual yield of chlorine is 18.11
Answer 2

The mass of MnCl2 that is produced when 0.091 g of Cl2 is generated is 0.16 g.

Molar mass of MnCl₂ = 55 + 35.5(2) = 126 g/mol

Molar mass of Cl₂ = 35.5(2) = 71 g/mol

If 71 g of Cl₂ gives 126 g of MnCl₂

0.091 g of Cl₂ will give ? of MnCl₂

cross multiply

mass of MnCl₂  produced  = 0.091 × 126 / 71

mass of MnCl₂  produced  = 11.466 / 71

mass of MnCl₂  produced  = 0.16149295774

mass of MnCl₂  produced  ≈ 0.16 g

Answers

Answer:

Excess reactant - Reactant that can produce more of the product

Limiting reactant - Reactant that can produce a lesser amount of the product

Theoretical yield - Amount of product predicted to be produced by the given reactants

Explanation:

In every chemical reaction, there is a limiting reactant and there is an excess reactant.

The limiting reactant determines the amount of product obtained. It is the reactant that produces a lesser amount of the product.

The excess reactant is known to be the reactant that produces a greater amount of the product.

The theoretical yield is calculated using the limiting reactant and is the amount of product predicted to be produced by the given reactants.

Answers

Answer:

Atom, cell, dust particle, ant, ping pong ball

Explanation:

Firstly, atoms make up all matter, including each of the items on that list. The only things smaller than atoms are the parts of the atom itself, protons, neutrons and electrons. Because none of those are on that list, atoms have to be the smallest. Next smallest is the cell. Cells are made up of atoms, but they also in part make up dust. You can see a dust particle with the naked eye, but in order to see a cell you must use a microscope. Thus, cells are smaller than dust particles. Next is an ant. Obviously, an ant is bigger than a speck of dust, and is made up of cells and atoms. Lastly all you have is the ping pong ball, which is much larger than the rest of the items. Hope this helps!

All matter, including each thing on the list, is made up of atoms. The protons, neutrons, and electrons that make up an atom are the only particles smaller than atoms.

Thus,  Atoms must be the tiniest object because none of those are included in that list. The cell is the next smallest. Atoms make up cells, but dust also makes up a portion of them.

A dust particle can be seen with the unaided eye, but a microscope is required to see a cell.

Cells are hence smaller than dust particles. An ant comes next. Of course, an ant is composed of cells and atoms and is larger than a particle of dust.

Thus, All matter, including each thing on the list, is made up of atoms. The protons, neutrons, and electrons that make up an atom are the only particles smaller than atoms.

According to the stoichiometry of the decomposition of water 6.04  grams of oxygen is produced assuming the decomposition goes to completion.

What is stoichiometry?

Stoichiometry is  defined as the determination of proportions of elements or compounds which are present  in a chemical reaction. The related relations are based on law of conservation of mass and law of combining weights and volumes.

Stoichiometry is used in quantitative analysis for measuring concentrations of substances present in the sample.It is useful in balancing chemical equations.According to the reaction, 36 g water gives 32 g oxygen thus 6.80 g water will give 6.80×32/36=6.04 g.

Thus, on  decomposition of water 6.04  grams of oxygen is produced assuming the decomposition goes to completion.

The mass of H₂O is 44,680 g for the given reaction 2H₂ + O₂ → 2H₂O. Therefore, the correct option is option A.

What is mass?

In physics, mass is a quantitative measurement of inertia, a basic characteristic of all matter. It essentially refers to a body of matter's resistance to changing its speed or location in response to the force that is applied. The change caused by either an applied force is smaller the more mass a body has.

The kilogramme, which is defined approximately equal to 6.6 × 10⁻³⁴ joule second in terms of Planck's constant, is the unit of mass inside the Worldwide System of Units (SI). A joule is equivalent to one kilogramme multiplied by one square metre per second. The mass of H₂O is 44,680 g for the given reaction 2H₂ + O₂ → 2H₂O.

You start with 100mL of 14M HNO3 and 10grams of copper metal. How many moles of the nitrogen dioxide gas will be produced?

Answers

Answer:

0.316 moles are produced.

Explanation:

We state the redox reaction:

4HNO₃   + Cu   →  Cu(NO₃)₂ + 2NO₂ + 2H₂O

We need to determine the limting reactant:

0.1 L . 14 M = 1.4 moles

10 g . 1mol/ 63.54g =0.158 mol

Cu is the limiting reactant. Let's see

4 moles of acid need 1 mol of Cu to react

1.4 moles of acid may react to (4 . 1) / 1.4 = 0.35 moles

We do not have enough Cu.

1 mol of Cu can produce 1 mol of NO₂

Then 0.158 moles will produce, 0.316 moles. (double of moles)

Answers

The carbon and silicon have in common that they belong to the same column (family), therefore they have the same number of total electrons. So, option B is correct.

What do carbon and silicon have in common?

Carbon's closest analogue is silicon. Silicon and carbon are both tetravalent atoms that primarily form covalent (non-ionic) compounds. However, aside from the fact that both elements "can form four covalent bonds," there is surprisingly little in common between them.

Carbon has an atomic number of 6 and an electronic configuration of 2, 4. Silicon has an atomic number of 14 and an electronic configuration of 2, 8, 4. Because both elements have the same number of valence electrons, they are classified as being in the same group.

Thus, option B is correct.

How many kilograms of chlorine gas is needed to produce 45.0 grams of hydrochloric acid?

Answers

Answer:

43.76 g = 0.04376 Kg

Explanation:

The equation of the reaction is given as;

H2 + Cl2 --> 2HCl

From the equation;

1 mol of Cl2 produces 2 mol of HCl

Converting to mass;

Mass = Number of mol * Molar mass

Cl2;

Mass = 1 mol * 70.906 g/mol = 70.906 g

HCl;

Mass = 2 mol * 36.458 g/mol = 72.916 g

This means;

70.906 g of Cl2 produces 72.916 g of HCl

x g of Cl2 would produce 45g of HCl

70.906 = 72.916

x = 45

x = 45 * 70.906 / 72.916

x = 43.76g
