Using the stoichiometry of the reaction, we can obtain the molar mass of the complex as 276 g/mol. The number of moles iron II as 0.00181 moles and the mass of iron II as  0.1 g.

A redox reaction is one in which there is loss or gain of electrons. The equation of the reaction is 5Fe2+ + MnO4- + 8H+ - - > 5Fe2+ + Mn2+ +4H2O

Number of moles of permanganate =   0.0200 mol. dm3 * 18.10cm3/1000 L

= 0.000362 moles

If 5 moles of iron II reacted with 1 mole of permanganate

x moles of iron II reacts with 0.000362 moles of permanganate

x = 5 moles * 0.000362 moles/ 1 mole

= 0.00181 moles of iron II

Recall that;

Number of moles = mass/molar mass

Molar mass of iron  II = 56 g/mol

0.00181 moles  = x/56 g/mol

x = 0.00181 moles * 56 g/mol = 0.1 g

If 1 mole of the complex contains 1 mole of iron then;

0.00181 moles = 500 * 10^-3/MM

MM= 500 * 10^-3/0.00181 moles

The chemical formula has been defined as the representation of the chemical symbols along with the coefficient and proportions. The chemical formula of the unknown compound X is Al₂O₃.

The chemical formula has been the representation of the relative numbers of the elemental atoms involved in the chemical substance that makes the molecule and the compound. The chemical formula of the unknown substance can be calculated from the number of moles.

The moles of the atom or the element represent the proportions of the atom involved in the various elements in the substance. The chemical formula is represented by letters, coefficients, subscripts, superscripts, parentheses, signs, etc.

Given,

Moles of compound X = 1 mol

Moles of Al element = 2 mol

Moles of O element = 3 mol

So the chemical formula of the unknown compound X will be Al₂O₃ as there are two moles of aluminum and three moles of oxygen in the compound.

Therefore, Al₂O₃ is the chemical formula of the unknown compound X.

A homogenous mixture varies from a heterogenous mixture in that a homogenous mixture has properties that do not vary in the mixture. The correct answer is A.

A homogeneous mixture is a mixture in which the properties and composition are uniform throughout the mixture. This means that if you took a sample from any part of the mixture, you would find the same properties and composition in that sample as you would find in the entire mixture.

In contrast, a heterogeneous mixture is a mixture in which the properties and composition vary throughout the mixture. For example, a salad is a heterogeneous mixture because you can see different ingredients such as lettuce, tomatoes, and croutons, each with different properties and composition.

So, in a homogeneous mixture, the properties do not vary, while in a heterogeneous mixture, the properties vary throughout the mixture.

When the weather is nice, many people begin to work on their yards and homes. For many projects, sand is needed as a foundation for a walk or to add to other materials. You could order up twenty million grains of sand and have people really stare at you. You could order by the pound, but that takes a lot of time weighing out. The best bet is to order by the yard, meaning a cubic yard. The loader can easily scoop up what you need and put it directly in your truck.

It certainly is easy to count bananas or to count elephants (as long as you stay out of their way). However, you would be counting grains of sugar from your sugar canister for a long, long time. Atoms and molecules are extremely small – far, far smaller than grains of sugar. Counting atoms or molecules is not only unwise, it is absolutely impossible. One drop of water contains about 10 22 molecules of water. If you counted 10 molecules every second for 50 years without stopping you would have counted only 1.6 × 10 10 molecules. Put another way, at that counting rate, it would take you over 30 trillion years to count the water molecules in one tiny drop.

The mass of the average marble in the sack is 12.35 g.

Total number of marbles in the bag = number of red marbles + number of green marbles

Mass of each green marble = 12.70g

Mass of each red marble = 11.50g

Total mass of green marbles = 24,351(12.70g) = 309257.70 g

Total mass of red marbles = 10,051(11.50g) = 115586.50 g

Total mass of marbles in the sack = 309257.70 g + 115586.5 g = 424844.22 g

Total number of marbles in the sack = 24,351 + 10,051 = 34402 marbles

Therefore;

Mass of the average marble in the sack = 424844.22 g/34402 marbles

= 12.35 g

Hence, the mass of the average marble in the sack is 12.35 g

Answer:

42.1 g of silver chloride (AgCl).

Explanation:

What is given?

Mass of silver nitrate (AgNO3) = 50.0 g.

Molar mass of silver nitrate (AgNO3) = 170 g/mol. (you can calculate this using the periodic table)

Molar mass of silver chloride (AgCl) = 143.4 g/mol.

Step-by-step solution:

First, let's balance the chemical equation by trial and error method:

You can see that we have Cl and NO3 unbalanced, so if we put '2' moles beside AgCl, chlorine (Cl) will be balanced for both sides, but Ag would be unbalanced and NO3 too, so if we put '2' moles beside AgNO3, we will obtain the balanced equation:

Now, let's do the stoichiometry of part a.

Let's convert 50.0 g of AgNO3 to moles using its given molar mass:

And now, let's see how many moles of AgCl are being produced by 0.294 moles of AgNO3. You can see in the chemical equation that 2 moles of AgNO3 reacted, produces 2 moles of AgCl, so the molar ratio is 2:2, more simply is 1:1. This means that if we're using 0.294 moles of AgNO3, we will obtain 0.294 moles of AgCl.

Based on this logic, the final step is to find the mass of AgCl in grams, using its molar mass, like this:

The answer is we will obtain 42.1 g of silver chloride (AgCl).

Answer:

Explanation:

Atomics number = number of protons

Answer:

b. a.

Explanation:

Answer:

a) IUPAC Names:

                   1) (trans)-but-2-ene

                   2) (cis)-but-2-ene

                   3) but-1-ene

b) Balance Equation:

                       C₄H₁₀O + H₃PO₄   →   C₄H₈ + H₂O + H₃PO₄

As H₃PO₄ is catalyst and remains unchanged so we can also write as,

                                    C₄H₁₀O   →   C₄H₈ + H₂O

c) Rule:

           When more than one alkene products are possible then the one thermodynamically stable is favored. Thermodynamically more substituted alkenes are stable. Furthermore, trans alkenes are more stable than cis alkenes. Hence, in our case the major product is trans alkene followed by cis. The minor alkene is the 1-butene as it is less substituted.

d) C is not Geometrical Isomer:

        For any alkene to demonstrate geometrical isomerism it is important that there must be two different geminal substituents attached to both carbon atoms. In 1-butene one carbon has same geminal substituents (i.e H atoms). Hence, it can not give geometrical isomers.
