AgNO₃ will act as the oxidising agent.

<h3><u>For the given chemical equation:</u></h3>

Cu + 2AgNO₃ →  2Ag + Cu(NO₃)₂

Half reactions for the given chemical reaction:

<u>Reducing agent:</u>

Cu → Cu²⁺ + 2e⁻

Copper is a reducing agent because it is losing 2 electrons, which causes an oxidation process.

<u>Oxidising Agent</u>:

Ag⁺ + e⁻ → Ag

The silver ion undergoes a reduction process and is regarded as an oxidizing agent since it is acquiring one electron per atom.

Hence, AgNO₃ is considered as an oxidizing agent and therefore the correct answer is Option B.

<h3><u>Oxidising and Reducing agents</u></h3>
  • An oxidizing agent is a substance that reduces itself after oxidizing another material. It passes through a reduction process in which it obtains electrons and the substance's oxidation state is decreased.
  • A reducing agent is a chemical that oxidizes after reducing another material. It passes through an oxidation process in which it loses electrons and the substance's oxidation state increases.

in 1965, the mean price of a new car was $2,650 and the standard deviation was $1,000. In 2011, the mean was $30,500 and the sta
miss Akunina [59]

Answer:

Car were more expensive in 2011

Explanation:

Data provided in the question:

Mean price of the car in 1965 = $2,650

Standard deviation, s = $1,000

Mean price of the car in 2011 = $30,500

Standard deviation in 2011, s = $9,000

Cost in 1965 = $2,300

Cost in 2011 = $28,000

Now,

z score = [ X - mean ] ÷ s

Therefore,

In 1965

z score = [ $2,300 - $2,650] ÷ 1,000

= -0.35

In 2011

z score = [ $28,000 - $30,500 ] ÷ 9,000

= -0.278

Since,

The standard score in 2011 is higher than in 1965

Hence,

Car were more expensive in 2011

Bowling with a volleyball instead of a bowling ball. Will this make it easier or harder to knock over pins?
riadik2000 [5.3K]

Answer:

Definitely harder, since volleyballs are nowhere near as heavy as bowling balls, it’ll be harder too since there wont be much force to knock over pins

Describe how phospholipids form a barrier between water inside the cell and water outside the cell
Lynna [10]
<span>Phospholipids would have to form a phospholipid bilayer in order to achieve water on the outside and water inside. This is because the nonpolar tails of the phospholipids are facing each other in a water environment because they cannot interact with the water, only their own tails, while the phosphate heads of the molecule face the periphery of the tails and interact with water. Micelles are the simplest examples of these.</span>

How many molecules are in 3.50 moles of H2O<br>​
Debora [2.8K]

Answer:

2.11 x 10²⁴ molecules.

Explanation:

  • <em>It is known that every 1.0 mole of a molecule contains Avogadro's number of molecules (NA = 6.022 x 10²³).</em>

<em><u>Using cross multiplication:</u></em>

1.0 mole of H₂O contains → 6.022 x 10²³ molecules.

3.5 mole of H₂O contains → ??? molecules.

∴ 3.5 mole of H₂O contain = (3.5 mol)(6.022 x 10²³) = 2.11 x 10²⁴ molecules.
