Answer: c. The specific heat of seawater

Explanation: Specific heat is defined as the amount of heat required to raise the temperature of unit mass of the substance by a given amount.

Concentration of ions is measured by noting the conductivity of the solution.As higher is the conductivity, higher is the concentration of ions.

Concentration of dissolved oxygen is measured by using iodometric titrations in which iodine is involved.

pH is measured by knowing the concentration of hydrogen ions.

If 57.3 l of 0.497 m koh is required to completely neutralize 39.5 l of a CH3COOH solution. What is the molarity of the acetic a
bearhunter [10]

The molarity of the solution will be 0.72 m.

The majority of reactions take place in solutions, making it crucial to comprehend how the substance's concentration is expressed in a solution when it is present. The number of chemicals in a solution can be stated in a variety of ways, including.

The symbol for it is M, and it serves as one of the most often used concentration units. Its definition states how many moles of solute there are in a liter of solution.

Given data:

V_{1} =57.3 L\\V_{2} = 39.5 L\\M_{1} = 0.497 m\\\\M_{2} = ?

Molarity can be determined by the formula:

M_{1} V_{1} = M_{2} V_{2}

where, M is molarity and V is volume.

Put the value of given data in above equation.

57.3 × 0.497 m = M × 39.5 L

M = 0.72 m

Therefore, the molarity of the solution will be 0.72 m

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.

Should vaccinations be required for students to attend public school?
irakobra [83]

Answer:

I don't think so for now, there hasn't been much research done with the vaccine and children so we really don't know how children's bodies will react to it. Once more studies are done with the vaccine and children and is proven safe then yes, kids should use it in order to attend public school.

How do you think heat moves through Earth's atmosphere?
Lynna [10]

Answer:

Conduction, radiation and convection all play a role in moving heat between Earth's surface and the atmosphere. Since air is a poor conductor, most energy transfer by conduction occurs right near Earth's surface. Conduction directly affects air temperature only a few centimeters into the atmosphere.
