9) Copper metal, Cu(s), will spontaneously reduce which of the following?

a) Fe2+ and Ag+

b) Fe2+

c) Ag+

d) Al3+

e) Fe2+ and Al3+

Answers

Copper metal Cu(s) will spontaneously reduce Fe2+ and Al3+. So the correct option is e. Fe2+ and Al3+

Cu(s), is a reducing agent since it is able to reduce other chemicals by donating electrons. Copper has a low standard reduction potential of -0.34 V, meaning it is able to reduce the oxidation state of many other elements. This includes both Fe2+ and Al3+ ions.

In the case of Fe2+, the reduction reaction would be Cu(s) + Fe2+ --> Cu2+ + Fe(s). For Al3+, the reaction would be Cu(s) + 2Al3+ --> 2Cu2+ + Al(s). On the other hand, Cu(s) is unable to reduce either Ag+ or Fe3+ since the reduction potential for both is lower than the reduction potential of Cu(s).

Therefore the correct option will be e. Fe2+ and Al3+

Is freezing point depression negative?

Answers

Yes, freezing point depression is negative because it is the decrease in the freezing point of a solvent when a non-volatile solute is added to it.

What is freezing point?

Freezing point is the temperature at which a liquid turns into a solid state. For example, water freezes at 0°C (32°F). At the freezing point, the particles of the liquid slow down to a point where they can no longer move freely and start to form a solid. This happens because the particles of the liquid form a crystal lattice structure when they reach their freezing point. The temperature at which this happens is called the freezing point. Different substances have different freezing points, depending on the type of particles that make up the substance.

Which equation represents the most accurate model of cellular respiration? note: c6h12o6 is the sugar, glucose.

Answers

The most accurate equation representing the model of cellular respiration is: D. C6H12O6 (sugar) + 6O2 (oxygen) --> 6CO2 (carbon dioxide) + 6H2O (water) + energy.

How does cellular respiration happen?

Cellular respiration is a metabolic process that breaks down glucose and oxygen to provide energy for plants. This energy is in the form of ATP energy essential to support many other reactions in the plant’s body. To produce this energy, plants react to glucose (C6H12O6) and oxygen to form ATP. The process also produces carbon dioxide and water as the side product. This reaction is also known as glycolysis, which most accurately represents as:

C6H12O6 (sugar) + 6O2 (oxygen) --> 6CO2 (carbon dioxide) + 6H2O (water) + energy.

Answer:

Hydrogen and helium are placed in different groups in the periodic table because they have different atomic numbers and different chemical properties......................................

Explanation:

In the periodic table, the elements are arranged according to their atomic number, which is the number of protons in the nucleus of an atom. The elements are also organized into groups, or families, based on their chemical properties.

Hydrogen and helium are placed in different groups in the periodic table because they have different atomic numbers and different chemical properties. Hydrogen is placed in group 1a, also known as the alkali metals, because it has a single valence electron, which is an electron that is involved in chemical bonding. Helium, on the other hand, is placed in group 8a, also known as the noble gases, because it has a full valence shell, which means that it does not readily form chemical bonds.

It is important to note that the arrangement of elements in the periodic table is not based on the choices or preferences of the elements themselves, but rather on their intrinsic properties, such as their atomic number and chemical behavior.

if the potential of a voltaic cell is 0.837 v, what is the free energy change when two moles of electrons are transferred in an oxidation-reduction reaction?

Answers

Gibb's free energy change is  -1,61,541Joules when two moles of electrons are transferred in an oxidation-reduction reaction.

In thermodynamics, the Gibbs free energy (or Gibbs energy ) is a thermodynamic potential that can be utilized to compute the greatest measure of work that might be performed by a thermodynamically shut framework at consistent temperature and pressure. It likewise gives an important condition to cycles, for example, substance responses that might happen under these circumstances.

For calculating free energy change, we need to know about the value of faraday constant and voltage of the cell.

We know that 1 faraday=96500Coloumb,voltage=0.837,n=2

So, free energy(ΔG)= - n × F × E°

=>ΔG= -2 × 96500× 0.837

=>ΔG= -193000×0.837

=>ΔG= -1,61,541Joules (Here negative sign shows that voltaic cell is possible in this universe).

PERCENT YIELD!!!
A sodium bromide solution containing 3.0 g of sodium bromide is reacted with excess dimercury (I) acetate solution


The mass of the dry precipitate is measured to be 4.000 g. Calculate the percent yield for the precipitate.

Answers

The percent yield of the reaction would be 49.17%.

Stoichiometic problem

Sodium bromide reacts with excess dimercury (I) acetate to produce  dimercury (I) bromide precipitate and sodium acetate according to the following balanced equation:

[tex]2NaBr(aq) + Hg_2(CH_3COO)_2(aq) -- > Hg_2Br_2(s) + 2NaCH_3COO(aq)[/tex]

The mole ratio of sodium bromide to the precipitate is 2:1.

Recall that: mole = mass/molar mass.

3.0 g of sodium bromide would be equivalent to: 3.0/102.89

= 0.029 mol

The equivalent mole of the precipitate produced = 0.029/2 = 0.0145 mol

Mass of 0.0145 mol dimercury (I) bromide = 0.0145 x 560.99

                                                                     = 8.1343 grams

Percent yield = 4/8.1343
