Multiple people cannot use one brainly account at the same time on a computer.

No, multiple people cannot use the same Brainly account at the same time on a computer. Brainly accounts are designed to be used by individual users and are intended for personal use. Each user should have their own separate account to access and interact with the Brainly platform. Sharing an account among multiple people simultaneously can lead to confusion, conflicts, and potential violations of the platform's terms of service. It is recommended that each person creates their own individual account on Brainly for a smooth and personalized experience.

Hence, multiple people can't access brainly at the same time.

Answer:

A. The sum of the voltages of the half-reactions is positive.

Explanation:

correct on  a p e x

Among the following redox conditions those will produce a spontaneous reaction is The sum of the voltages of the half-reactions is positive.

Redox reactions are the reactions in which reduction reaction and oxidation reaction happens simultaneously. The term ‘redox’ is a short form of reduction-oxidation. All the redox reactions can be broken down into two different processes: a reduction process and an oxidation process.

The loss of electrons and the corresponding increase in the oxidation state of a given reactant is called oxidation. The gain of electrons and the corresponding decrease in the oxidation state of a reactant is called reduction.

For example-

H₂ + F₂ → 2HF

Hydrogen is added to Fluorine gas so Fluorine has been reduced but Hydrogen has been oxidised.

Therefore, Among the following redox conditions those will produce a spontaneous reaction is The sum of the voltages of the half-reactions is positive.

Answer:

A. Al(s)

Explanation:

Answer:

A and D takes much slower

Explanation:

Here, we want to select, out of the four given reactions, the one that is slower than the other two

The answers in these case are reactions 1 and 4 ( A and D)

The two reactions show what is called rust (as directly seen in reaction 4)

When we speak of rust, we simply mean a reaction that occurs over time

For example, non coated roofings of houses doesn’t get to change color at an instant

The color degradation that occurs is something that takes some time from the initial time they were used to roof the house

Hence, from these analogy, we can see that these reactions need an an external support to thrive or to come into existence

These external supports are natural forces and they contributing efforts occur over time and cannot be seen immediately

These reactions are thus ones that take much slower time than conventional laboratory reactions in the case of the formation of the precipitate or a reaction that requires a low flash point temperature such as that of black powder to produce such explosive effects

So in conclusion, what we are saying is that the two selected reactions are subjected to the availability of some conditions and may take time to manifest and these absolutely differentiates them from reactions that are spontaneous such as the one having an explosive effect or the other one leading to the formation of a precipitate which takes far less times

Answer:

Therefore, the pressure exerted by the hydrogen gas that was trapped over water is 108.8 kPa

Explanation:

The law of partial pressure by Dalton, in a mixture of gases which do not react chemically together, the total pressure is equal to the sum of the partial pressures of the individual gases.

According to this law, the total pressure exerted by the gases above the displaced water is equal to the sum of the partial pressure of water vapor and the partial pressure of hydrogen gas: Ptotal = pH₂ + pH₂O

Therefore, pH₂ = Ptotal - pH₂O

Vapor pressure of water at 37°C = 3.17 kPa; Ptotal = 102.0 kPa

pH₂ = (102.0 - 3.17) kPa

pH₂ = 98.8 kPa

Therefore, the pressure exerted by the hydrogen gas that was trapped over water is 108.8 kPa

The Ring of Fire, also referred to as the Circum-Pacific Belt, is a path along the Pacific Ocean characterized by active volcanoes and frequent earthquakes. The majority of Earth's volcanoes and earthquakes take place along the Ring of Fire

Explanation:

google

Answer:

Most earthquakes occur along the edge of the oceanic and continental plates. The belt exists along boundaries of tectonic plates, where plates of mostly oceanic crust are sinking beneath another plate.

Most volcanoes are found along a belt, called the “Ring of Fire” that encircles the Pacific Ocean. As the plates move, they spread apart, collide, or slide past each other. Sixty percent of all active volcanoes occur at the boundaries between tectonic plates.

Answer:

Crossing over happens when pairs of chromosomes pair up

Crossing over creates new combinations of genes on chromosomes.

Explanation:

The correct answer would be that crossing over happens when pairs of chromosomes pair up, exchange chromosomal segments, and create new combinations of genes on chromosomes.

Crossing over occurs during prophase I of meiosis when homologous chromosomes pair up to form a tetrad. Paired chromosomes then exchange chromosomal segments containing genes leading to a new combination of genes on each chromosome. Hence, the resulting daughter cells are genetically different from the original cell.

Answer: B. To connect two electrodes

Explanation:

The salt bridge forms a connecting link between the two electrodes. The function of the salt bridge is not to supply electrons from one electrolyte to another but to maintain a constant balance of charge as the electrons move from one half of the cell to the another. The electrons from from negative electrode to positive electrode that is from anode to cathode.

Answer:

Giant cell, also called Langhans giant cell, large cell characterized by an arc of nuclei toward the outer membrane. The cell is formed by the fusion of epithelioid cells, which are derived from immune cells called macrophages. Once fused, these cells share the same cytoplasm, and their nuclei become arranged in an arc near the outer edge of the cell. Langhans giant cells typically form at the centre of granulomas (aggregates of macrophages) and are found in the tubercle, or primary focus of infection, in tuberculosis, in lesions of syphilis, leprosy, and sarcoidosis, and in fungal infections.Large cells that form by fusion in reaction to the presence in the body of foreign substances differ from Langhans giant cells in that their many nuclei are scattered throughout the cell. In giant-cell tumours of bone and tendon the cells have many nuclei crowded together. The megakaryocytes, the normal bone-marrow cells thought to be the source of the blood platelets, are also called giant cells.

I'M WORKING ON THIS SUBJECT TOO!!!!!

It's been a while since I've taken Chemistry but here's what I know:

There are small, weak bonds that form between water molecules. These bonds make it so liquid molecules (water, in this example) cannot move as freely as a gas, but their bonds aren't nearly as strong as a solid. The bonds are formed when a hydrogen atom is attracted to an oxygen atom (because they have an opposite charge). This bond plus the gas molecules hitting the water causes surface tension.
