speed and direction in which an object is moving. both speed and direction of motion. is a vector. two or more velocities add by velocity addition.
For the reaction Cl₂(aq) + 2 Br⁻(aq) ⇒ 2Cl⁻(aq) + Br₂(aq), Chlorine (Cl) is the oxidizing agent because it gains an electron.
<h3>What is the oxidizing agent?</h3>
In a redox reaction, the oxidizing agent is the one that gains electrons, causing the other element to oxidize.
Let's consider the following redox reaction.
Cl₂(aq) + 2 Br⁻(aq) ⇒ 2Cl⁻(aq) + Br₂(aq)
The corresponding half-reactions are:
Reduction: 2 e- + Cl₂(aq) ⇒ 2Cl⁻(aq)
Oxidation: 2 Br⁻(aq) ⇒ Br₂(aq) + 2 e-
Which best describes the oxidizing agent in this reaction?
- Bromine (Br) is the oxidizing agent because it gains an electron. NO. Br is the reducing agent.
- Bromine (Br) is the oxidizing agent because it loses an electron. NO. Br is the reducing agent.
- Chlorine (Cl) is the oxidizing agent because it gains an electron. YES.
- Chlorine (Cl) is the oxidizing agent because it loses an electron. NO. Cl gains electrons.
For the reaction Cl₂(aq) + 2 Br⁻(aq) ⇒ 2Cl⁻(aq) + Br₂(aq), Chlorine (Cl) is the oxidizing agent because it gains an electron.

#SPJ1
The answer is (3), oxidation occurs at the anode and reduction occurs at the cathode. That's because the oxidation reaction can lose electrons and reduction can gain electrons.
Answer:
The footprints of a dinosaur and the burrow of an ancient shrimp are examples of - Trace Fossils
Explanation:
A trace fossil or ichnofossil is defined as a geological record of biological activity. These provide us with indirect evidence of life in the past, such as the footprints, burrows, tracks, borings, etc that are left behind by animals, rather than the preserved remains of the body of the actual animal itself.
It is C that is the most testable hypotheses
