Which of the following is the balanced net ionic equation for an oxidation-reduction reaction between ag (aq) and ni(s) based on the half-reactions represented above?

Ag (aq) +e â Ag(s)
a. Ag+ (aq) + Ni(s) â Ag(s) + Ni²+(aq)
b. 2 Ag+ (aq) + Ni(s) â Ag(s) + 2Ni2+
c. Ag+(aq) + 2Ni(s) â Ag(s) + 2NiZ+(aq)
d. 2Ag+(aq) + Ni(s) â 2Ag(s) + Ni²+(aq)

Answers

Answer 1

The balanced net ionic equation for an oxidation-reduction reaction between Ag+ (aq) and Ni(s) based on the half-reactions represented above is: d. 2Ag+(aq) + Ni(s) â 2Ag(s) + Ni²+(aq)

The reason is that both half-reactions must be balanced for both electrons and atoms, so the number of electrons lost by the oxidation half-reaction must equal the number of electrons gained by the reduction half-reaction. In this case, the oxidation half-reaction is: Ag+(aq) + e- -> Ag(s) which loses 1 electron. The reduction half-reaction is: Ni(s) -> Ni²+(aq) + 2e- which gains 2 electrons. To balance the number of electrons between the two half-reactions, we need to multiply the oxidation half-reaction by 2, so that it loses 2 electrons. So the balanced net ionic equation is 2 Ag+(aq) + Ni(s) -> 2 Ag(s) + Ni²+(aq).

Answers

In determining the reactivity of an electrophile in a nucleophilic substitution reaction, steric hindrance plays an important factor.

According to the concept of electrophilicity, an electron-deficient atom(electrophile) is attacked by electron-rich species (nucleophile).

SN2 reactions occur in primary, secondary  and methyl carbon electrophiles.

What is the final temperature of the liquid that is formed when 50 grams of ice and 500 g of water are mixed together?

The final temperature of the liquid that is formed when 50 grams of ice and 500 g of water are mixed together is determined as follows:

Heat gained = Heat lost

Heat change = mc(T_f - Ti)

The heat of fusion = mL

where;

m is the massc is the specific heatT_f is the final temperatureTi is the initial temperatureL is the latent heat of fusion of ice = 0.334 J/g

Heat lost water = mc(T_f - Ti)

c for water = 4.19 J/J/(g°C)

Heat lost water = 500 * 4.18 * (T_f - 20)

Heat lost water = 2090T_f - 41800

Heat gained by ice = mc(T_f - Ti) + mL + mc(T_f - Ti)

c for ice = 2.03 J/J/(g°C)

Heat gained by ice = 50 * 2.03 * {0 - (-20)} + 50 * 0.334 + 50 * 4.18 * (T_f - 0)

Heat gained by ice = 2046.7 + 209T_f

From heat gained = heat lost;

2046.7 + 209T_f = 2090T_f - 41800

2090T_f - 209T_f = 2046.7 + 41800

When two bodies, such as two pool cues, a golf club and a ball, a hammer and a nail, two railroad cars when united, or a falling object and a floor, abruptly and forcefully contact, it causes a collision, also known as an impact.

It is necessary for reacting chemicals to collide, and for that collision to occur in the right direction and with sufficient energy. The collision hypothesis must meet these three conditions.

Answers

For an experiment, you are asked to prepare a 2 m strong electrolytic solution. The salts you might use is an alkali salt.

ABOUT ALKALI SALT

Alkali salts or basic salts are salts which are the result of neutralization of strong bases and weak acids.

Instead of being neutral (like some other salts), the alkaline salt is basic as the name suggests. What makes this compound basic is that the conjugate base of a weak acid hydrolyzes to form a basic solution. In Sodium carbonate, for example, the carbonate from carbonic acid hydrolyzes to form a basic solution. The chloride from hydrochloric acid in sodium chloride is not hydrolyzed, so sodium chloride is not alkaline.

The difference between basic salt and alkali is that alkali is a soluble hydroxide compound of an alkali metal or alkaline earth metal. Alkaline salts are salts that hydrolyze to form alkaline solutions.

Another definition of a basic salt is a salt that contains a certain amount of hydroxide and other anions. White lead [en] is an example. This is basic lead carbonate, or hydroxide lead carbonate.

This material is known for its high solubility in polar solvents.

These salts are insoluble and can be obtained through precipitation reactions.

A small speck of carbon the size of a pinhead contains about 2×1019 atoms, the diameter of a carbon atom is 1.5×10−10 m, and the circumference of the earth at the equator is 40,075 km. How many times around the earth would the atoms from this speck of carbon extend if they laid side by side?

Answers

Answer:

233.3 times

Explanation:

The diameter of a carbon atom is 1.5 x 10^-10 meters, so the circumference of a carbon atom is pi x diameter = 3.14 x 1.5 x 10^-10 m = 4.71 x 10^-10 m

If you have 2 x 10^19 atoms in a small speck of carbon and all the atoms laid side by side, the total circumference of all the atoms would be 2 x 10^19 x 4.71 x 10^-10 = 9.42 x 10^9 meters.

The circumference of the earth at the equator is 40,075 km, so that is 40,075 x 1000 = 40,075,000 meters.

Divide the total circumference of all the atoms by the circumference of the Earth:

9.42 x 10^9 m / 40,075,000 m = 233.3 times

Therefore, the atoms from this speck of carbon would extend around the Earth 233.3 times if they laid side by side.

true/false. chemists knew that something other than mass influences the properties of elements if you were a chemist what questions wouild you ask about elements and their atoms that could help you discover more aobut their properties

Answers

True: Chemists knew that something other than mass influences the properties of elements.

The periodic table organizes elements according to periodic properties, which are recurring trends in physical and chemical properties. First, electrons are added one at a time across a period, from left to right. As this occurs, the electrons in the outermost shell experience increasing nuclear attraction, bringing them closer to the nucleus and more tightly bound to it. Second, moving down a column in the periodic table loosens the outermost electrons' bond to the nucleus. Thus, number of valence electrons, or valency, other than mass influences the properties of elements.

This occurs because the number of filled principal energy levels (which protect the outermost electrons from nucleus attraction) decreases within each group. The periodicity observed in the elemental properties of atomic radius, ionization energy, electron affinity, and electronegativity are explained by these trends.

The order in which atomic orbitals are filled depends on the relative energies of the subshells (1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, and so on).

How are atomic orbitals filled?The energy of the orbitals in which the electrons are present is increased in this order, starting with the lowest energy orbital and working up to the highest energy orbital.Consequently, the primary quantum number (n) and azimuthal quantum number values affect the energy of orbitals (l). As a result, an orbital's energy decreases with decreasing values of (n + l).A shell has as many orbitals as the square of the primary quantum number, which is 12 = 1, 22 = 4, and 32 = 9. Three orbitals make up a p subshell, three orbitals make up a d subshell, and five orbitals make up a s subshell (l = 0).
