Wrap a magnet in plastic lunch wrap and move it through the mixture of the three solids. The iron filings will stick to the magnet. The filings can be removed by unwrapping the plastic from the magnet carefully! Mix the remaining salt and sand in water and stir.

Which best describes the oxidizing agent in this reaction?

MissTica

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.

Which has greater Mass 10 mL of steel (Density

masya89 [10]

The steel would have a mass of 78g and the mercury would have a mass of 68g. So the Steel has greater mass.

Explained: This picture I also attached explains that whenever you have an equation dealing with density and volume alone, you will multiply the 2 together to get your answer for mass. And when your dealing with mass and rather volume or density you will divide the mass by whatever the volume or density is. For example if you need to find the density of an object that is 25g and 14ml you will write out this equation 25g/14ml= 1.78 g/ml. And if you need to find the mass of an object that is 27ml and 14g/ml you will write an equation like this 27mlX14g/ml= 378g. I hope this helps with your understanding.
