What is the compound name for the ion chemical formula AgBr?

What would you predict to be the valence number and oxidation number of tin?

murzikaleks [220]

Answer:

Tin exists in two oxidation states, +4 and +2. Elemental tin is readily oxidized to the dipositive ion in acidic solution, but this Sn2+ ion is converted to the Sn4+ ion by many mild oxidizing agents, including elemental oxygen. Oxidation under alkaline conditions normally gives the tetrapositive (Sn4+) state.

What is an energy sublevel

Dominik [7]

Answer:

A sublevel is an energy level defined by quantum theory.

Explanation:

In chemistry, sublevels refer to energies associated with electrons. In physics, sublevels may also refer to energies associated with the nucleus.

In a redox reaction, electrons are transferred from the substance being reduced to the oxidizing agent.

babymother [125]

<u>Answer:</u> The correct answer is from the substance being oxidized to the substance being reduced.

<u>Explanation:</u>

Redox reaction is defined as the reaction in which oxidation and reduction reaction occur simultaneously.

Oxidation reaction is defined as the reaction where an atom looses its electrons. The oxidation number of the atom gets increased during this reaction.

$X\rightarrow X^{n+}+ne^-$

Reducing agents are defined as the agents which reduces the other substance and itself gets oxidized. These agents undergoes reduction reactions.

Reduction reaction is defined as the chemical reaction where an atom gains electrons. The oxidation number of the atom gets reduced during this reaction.

$X^{n+}+ne^-\rightarrow X$

Oxidizing agents are defined as the agents which oxidize other substance and itself gets reduced. These agents undergoes reduction reactions.

Electrons are transferred from one atom to another in this type of reaction from the substance which is getting oxidized to the substance which is getting reduced.

It can also be said that, electrons are transferred from reducing agent to the oxidizing agent.

Hence, the correct answer is from the substance being oxidized to the substance being reduced.

During an experiment a student measured the temperature of water while it boiled in a pot on a stove. The temperature of the wat

Answer:

c,interpretation of the data

Explanation:

A good scientific explanation needs to be based on both data collected in an investigation and on the ability to interpret what the data means.

Normally, adding heat energy increases the temperature of a substance. However, during a phase change, the temperature of the substance stays constant. This happens because the heat energy is being used to change the phase of the matter instead of the temperature.
