br2 au3 in each pair is a better oxidizing agent under standard-state conditions
In a redox chemical process, an oxidizing agent is a material that obtains or "accepts" or "receives" an electron from a reducing agent (also known as an oxidant, oxidizer, electron recipient, or electron acceptor) (called the reductant, reducer, or electron donor). Halogens (such as chlorine and fluorine), oxygen, and hydrogen peroxide are typical examples of oxidizing agents (H2O2).
The best oxidizing agent is fluorine, which also has the highest positive electrode potential value. Hydrogen peroxide, which is more potent than chlorine, chlorine dioxide, and potassium permanganate, is one of the most efficient oxidizers ever discovered. Normally, the oxidizing agent absorbs these electrons for itself, becoming reduced and acquiring electrons in the process. An electron acceptor is therefore an oxidizing agent.

Answer:
1a. Both sides of the decay reaction have the same charge.
b. The number of nucleons on both sides are the same.
2. The binding energy of one mole of the atom is 17.172 × 
J.
Explanation:
1a. Considering the two sides of the decay reaction and with respect to the law of conservation of charge, it can be observed that both sides have the same charge. Charge can not be created or destroyed in the process.
b. The number of nucleons on both sides are equal. No nucleon is created or destroyed in the process.
2. Binding energy is the minimum energy required to separate an atom into its nucleons. From Einstein's energy equation;
E = Δm
Where E is the binding energy of the atom, Δm is the mass defect and c is the speed of light.
Given that: Δm = 1.908 g/mol and c = 3 × 
. So that:
E = 1.908 × 
= 1.908 × 9 ×
= 17.172 × J
The binding energy of one mole of the atom is 17.172 × J.
Answer:
Explanation:
The oxidation reduction reactions are called redox reaction. These reactions are take place by gaining or losing the electrons and oxidation state of elements are changed.
Oxidation:
Oxidation involve the removal of electrons and oxidation state of atom of an element is increased.
Reduction:
Reduction involve the gain of electron and oxidation number is decreased.
Oxidizing agents:
Oxidizing agents oxidize the other elements and itself gets reduced.
Reducing agents:
Reducing agents reduced the other element are it self gets oxidized.
In given example,
Magnesium is able to <u>reduced</u> the copper and copper is able to <u>oxidized</u> the magnesium.
Zinc is able to <u>oxidized</u> the magnesium and magnesium is able to <u>reduced</u> the zinc.
Copper is able to <u>oxidized</u> the zinc and zinc is able to <u>reduced</u> the copper.
One is when water turns to ice. The water evaporates and turns into vapor but does not turn into liquid. Instead, it turns into ice.
The answer is a compound because it is only a compound that can be broken to elements. for eg. H2o is a compound and be broken to element of 2 molecules of hydrogen and oxygen
