Fe2O3 (s) + CO (g) -> Fe(s) + CO2 (g) (unbalanced)
1.Calculate the number of grams of CO that can react with 0.150kg of Fe2O3
2. Calculate the number of grams of Fe and the number of grams of CO2 formed
when 0.150 kg of Fe2O3 reacts

Answers

Answer:

1. 78.9g of CO

2. 104.9g Fe and 124.0g CO2

Explanation:

Based on the balanced reaction:

Fe2O3 (s) + 3CO (g) -> 2Fe(s) + 3CO2 (g)

1 mole of Fe2O3 reacts with 3 moles of CO to produce 2 moles of Fe and 3 of CO2

1. The moles of 0.150kg = 150g of Fe2O3 -Molar mass: are:

150g * (1mol / 159.69g) = 0.9393 moles Fe2O3

Moles CO:

0.9393 moles Fe2O3 * (3mol CO / 1mol Fe2O3) = 2.818 moles CO

Mass CO -Molar mass: 28.01g/mol-:

2.818 moles CO * (28.01g/mol) = 78.9g of CO

2. The moles of Fe produced are:

0.9393 moles Fe2O3 * (2mol Fe / 1mol Fe2O3) = 1.8786 moles Fe

Mass Fe -Molar mass: 55.845g/mol-:

1.8786 moles Fe * (55.845g/mol) = 104.9g Fe

The moles of CO2 produced are:

0.9393 moles Fe2O3 * (3mol CO2 / 1mol Fe2O3) = 2.818moles CO2

Mass CO2 -Molar mass: 44.01g/mol-:

2.818moles CO2 * (44.01g/mol) = 124.0g CO2

Se forma un radical etano cuando el etano, C₂H₆ reacciona con un radical libre de cloro, Cl *, como sigue;

C₂H₆ + Cl → C₂H₅ * + HCl

Se forma un producto halogenado cuando un radical libre de etano reacciona con una molécula de cloro como sigue;

C₂H₅ * + Cl₂ → C₂H₅Cl + Cl *

Answers

Answer: The correct net ionic equation for the reaction is [tex]2H^{+}(aq)+2OH^{-}(aq)\rightarrow 2H_2O(l)[/tex]

Explanation:

Net ionic equation is defined as the equations in which spectator ions are not included.

Spectator ions are the ones that are present equally on the reactant and product sides. They do not participate in the reaction.  

The balanced molecular equation is:

[tex]Ca(OH)_2(aq)+H_2SO_4(aq)\rightarrow CaSO_4(aq)+2H_2O(l)[/tex]

The complete ionic equation follows:

[tex]Ca^{2+}(aq)+2OH^-(aq)+2H^+(aq)+SO_4^{2-}(aq)\rightarrow 2Ca^{2+}(aq)+SO_4^{2-}(aq)+H_2O(l)[/tex]

As calcium and sulfate ions are present on both sides of the reaction. Thus, they are considered spectator ions.

The net ionic equation follows:

[tex]2H^{+}(aq)+2OH^{-}(aq)\rightarrow 2H_2O(l)[/tex]

Hence, the correct net ionic equation for the reaction is [tex]2H^{+}(aq)+2OH^{-}(aq)\rightarrow 2H_2O(l)[/tex]

Michael is studying the factors that affect corrosion of metals. He wants to test the effect that different concentrations of an acid will have on the corrosion of a metal. As he sets up and completes his experiment, which of the following experimental designs would be most likely to help him answer his question? A. Allow several metal samples to soak in different amounts of acid of a single concentration and then measure the amount of corrosion on each. B. Prepare solutions of different acid concentrations, measure 50 milliliters of each into different beakers, and place metal samples of different types but of the same mass into the beakers. C. After allowing several small metal sheets to be exposed to different acid concentrations, measure the surface area of each that is corroded. D. After allowing a small metal sheet to be exposed to one acid concentration, place it in different acid concentrations, then measure the surface area that is corroded.

Answers

Answer:

B. Prepare solutions of different acid concentrations, measure 50 milliliters of each into different beakers, and place metal samples of different types but of the same mass into the beakers.

Explanation:

Since Michael is studying the factors that affect corrosion of metals, and wants to test the effect that different concentrations of an acid will have on the corrosion of a metal, using different acid concentrations of the same volume on different metal samples of the same size would give a much better than all the other options because, a standard volume of acid is used and also a standard mass of metal is used. So, the effect can be measured quantitatively since we have the same quantity of sample.

So, option B is the answer

How many Carbon Atoms are there on the PRODUCT SIDE

Answers

Answer: There are 6 carbon atoms on the product side.

Explanation:

The given reaction equation is as follows.

[tex]6CO_{2} + 6H_{2}O \rightarrow C_{6}H_{12}O_{6} + 6O_{2}[/tex]

Species present on the left side of an arrow in a chemical equation depicts the reactants.

Species present on the right side of an arrow in a chemical equation depicts the products.

Hence, products in the given reaction equation are [tex]C_{6}H_{12}O_{6}[/tex] and [tex]6O_{2}[/tex].

Therefore, there are 6 carbon atoms present on the product side.

Thus, we can conclude that there are 6 carbon atoms on the product side.

The theoretical yield of NH3 is 945 grams. You conducted the experiment and only produced 598 grams.

Answers

Answer:

Given theoretical yield of NH3 is 945g.

The actual yield is 598g.

What is the %yield?

Explanation:

%yield of a chemical reaction can be calculated by using the formula:

[tex]%yield=\frac{actual yield}{theoretical yield} * 100[/tex][tex]\frac{actual yield}{theoretical yield} * 100[/tex]

Substitute the given values in this formula to get the %yield.

[tex]\frac{598g}{945g} * 100\\=63.3[/tex]

Hence, the %yield for the formation of ammonia is ---- 63.3.

How much heat is required to raise the temperature of 16.0 grams H2O from 5.000C to 75.00C? Below is a list of constants.

specific heat for H2O(s) = 2.1 J/g0C

specific heat for H2O(L) = 4.18 J/g0C

specific heat for H2O(g) = 1.7 J/g0C

\bigtriangleup H△Hvap = 40.7 kJ/mol

\bigtriangleup H△Hfus = 6.01 kJ/mol





5.34 J


260 J


4680 J


2350 J

Answers

Answer:

The amount of heat required is 4681.6 J.

Explanation:

mass, m = 16 g = 0.016 kg

initial temperature, T = 5 C

final temperature, T' = 75 C

specific heat, c = 4.18 J/g C

The amount of heat required is

H = m c (T'- T)

H = 16 x 4.18 x (75 - 5)

H = 4681.6 J

Which substance would you expect to dissolve most rapidly in 100 mL water?

A
0.4 g granulated sugar

B
0.2 g powdered sugar

C
0.4 g powdered sugar

D
0.2 g sugar cube

Answers

Answer:

b because it is just 0.2 g and powdered sugar has more contact surface than granulated sugar or sugar cube

The solubility can be given as the amount of solute that can be dissolved in the 100 ml of the solution. The most rapidly dissolved sugar in water is 0.2 gram powdered sugar.

What is a contact surface?

The contact surface can be given as the area of the compound that is in direct contact with the solution.

The solubility of the compound is found more in the solute with increased surface area.

The surface area of powdered sugar will be maximum, as more granules of the sugar will be in contact with the water than the cube or the granulated sugar.

Thus, the most rapid dissolution in water is found with 0.2 grams of powdered sugar. Thus, option B is correct.

Answer:A

Explanation:

Option D. They all have extremely long half-lives makes radioisotopes useful for dating objects.

What are radioisotopes?

Radioisotopes exist as radioactive isotopes of an element. They can also be described as atoms that include an unstable combination of neutrons and protons, or surplus energy in their nucleus.

A radionuclide exists as a nuclide that contains excess nuclear energy, causing it unstable. This excess energy can be utilized in one of three methods: emitted from the nucleus as gamma radiation; assigned to one of its electrons to terminate it as a conversion electron; or utilized to create and emit a unique particle from the nucleus.

Radioactive isotopes of radium, thorium, and uranium, for example, exist found naturally in rocks and soil. Uranium and thorium also happen in trace amounts in water. Radon, induced by the radioactive decay of radium, stands present in the air.

Hence, Option D. They all have extremely long half-lives makes radioisotopes useful for dating objects.
