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.

Explanation:

Option D is the correct Lewis structure of ozone.

Ozone is known to be an allotrope of oxygen which has three atoms of oxygen.

In the Lewis structure of ozone, one pair of oxygen is actually double-bonded while the other is single-bonded. In this structure, two oxygen atoms carry charges. In the drawing the Lewis structure of ozone, we discover that one oxygen atom of the ozone has a -1 charge and while another oxygen atom of the ozone has a +1 charge.

How many carbon atoms are there in a 12.5 kg sample of carbon?
step by step solution

Answers

Answer:

6.27 X 10^26 atoms

Explanation:

Write down the formula:

number of moles = mass/Ar    (Ar is atomic mass)

Ar of carbon = 12

mass = 12.5kg or 12500g

Substitue these values into the formula:

number of moles = 12,500g / 12 = 3125/3 or 1041.6

Convert this to atoms:

1 mole = 6.022 X 10^23 atoms

So, 1041.6 moles = 6.27 X 10^26 atoms

Explanation:

(LAW OF CONSERVATION)

The amount of oxygen and gasoline that can be produced is 5.6 liters

The question above is answered with the law of conversation of mass. This law of conversation of mass states that  no form of energy can be destroyed, instead it is changed from one form to another type of form.

In this law, it is expected that you end with the same amount you started with. According to the question above, since the amount that you started  with is 5.6 liters then you will end with 5.6 liters also.

A molar ratio is the proportions of reactants and products using the balanced equation. When writing a mole ratio, the given information must cross out with the right thing.

7.28 mol H2SO4 * 1 mol Na2SO4/1 H2SO4 = 7.28 mol Na2SO4

Why is 1/t used as a measure of rate of reaction?​

Answers

1/t denotes that the reaction order is of the first order. That is, the rate of reaction is directly proportional to the concentration of the reactant. Because scientists use standard units, 1/t equals one divided by one second.

What do you mean by first order reaction ?

The term first order reaction is defined as a chemical reaction in which the reaction rate is linearly dependent on the concentration of only one reactant.

In other words, a first-order reaction is a chemical reaction in which the rate varies as the concentration of only one of the reactants changes.

Because a reaction that takes longer to complete is obviously a slower reaction. A fast reaction is one that takes less time to complete. 1/t simply provides a quantitative value for comparing reaction rates.

Thus, 1/t denotes that the reaction order is of the first order.

explain why a nanowire can be longer than 3000nm but still be considered a metallic nanomaterial​

Answers

Answer:

A nanowire is a nanostructure, with the diameter of the order of a nanometre (10−9 meters). It can also be defined as the ratio of the length to width being greater than 1000. Alternatively, nanowires can be defined as structures that have a thickness or diameter constrained to tens of nanometers or less and an unconstrained length. At these scales, quantum mechanical effects are important—which coined the term "quantum wires". Many different types of nanowires exist, including superconducting (e.g. YBCO[1]), metallic (e.g. Ni, Pt, Au, Ag), semiconducting (e.g. silicon nanowires (SiNWs), InP, GaN) and insulating (e.g. SiO2, TiO2). Molecular nanowires are composed of repeating molecular units either organic (e.g. DNA) or inorganic (e.g. Mo6S9−xIx).

When silver nitrate (AgNO3) dissolves in water, the temperature of the solution decreases.
Explain your answer

Answers

Answer:

The enthalpy of solution for AgNO3 is positive because the temperature of the solution decreases (the dissolution is endothermic). Hsol = Hsolute + Hsolvent + HmixHsolute and Hsolvent are endothermic because energy is required to overcome intermolecular forces and separate solute and solvent particles.

Answer:

the enthalpy of solution for agno3 is positive because the temperature of the solution decreases. (the dissolution is endothermic.)

Delta H sol=delta HSolute +delta H solvent +delta H mix

HSolute and H solvent are endothermic because energy is required to overcome intermolecular forces and separate solute and solvent particles.

H mix is exothermic because energy is released when intermolecular forces form between solute and solvent particles.

if the overall enthalpy of solution is positive, then HSolute + H solvent must be larger in magnitude than H mix.
