Meteoroids are small objects in space, usually made of rock or metal. These bodies often get close to a planet and fall through

its atmosphere. A burning streak of light, called a
, is visible as it falls through the sky. Sometimes the object does not burn up completely and a part of it survives the fall to the planet’s surface. These rocky bodies, called

What we call "tin cans" are really iron cans coated with a thin layer of tin. The anode is a bar of tin and the cathode is the i
UNO [17]

Answer:

Fe (s) + Sn^{2+} (aq)\rightarrow Fe^{2+} (aq) + Sn (s)

Explanation:

Although the context is not clear, let's look at the oxidation and reduction processes that will take place in a Fe/Sn system.

The problem states that anode is a bar of thin. Anode is where the process of oxidation takes place. According to the abbreviation 'OILRIG', oxidation is loss, reduction is gain. Since oxidation occurs at anode, this is where loss of electrons takes place. That said, tin loses electrons to become tin cation:

Sn (s)\rightarrow Sn^{2+} (aq) + 2e^-

Similarly, iron is cathode. Cathode is where reduction takes place. Reduction is gain of electrons, this means iron cations gain electrons and produce iron metal:

Fe^{2+} (aq) + 2e^-\rightarrow Fe (s)

The net equation is then:

Sn (s) + Fe^{2+} (aq)\rightarrow Fe (s) + Sn^{2+} (aq)

However, this is not the case, as this is not a spontaneous reaction, as iron metal is more reactive than tin metal, and this is how the coating takes place. This implies that actually anode is iron and cathode is tin:

Actual anode half-equation:

Fe (s)\rightarrow Fe^{2+} (aq) + 2e^-

Actual cathode half-equation:

Sn^{2+} (aq) + 2e^-\rightarrow Sn (s)

Actual net reaction:

Fe (s) + Sn^{2+} (aq)\rightarrow Fe^{2+} (aq) + Sn (s)

A sample of oxygen gas at a pressure of 0.656 atm and a temperature of 27.2 °C, occupies a volume of 10.7 liters. If the gas is
sladkih [1.3K]

Answer:

The correct answer is 0.536 atm.

Explanation:

The formula to use to solve the given question is,

P1V1 = P2V2

Based on the given information, the initial pressure (P1) of the oxygen gas is 0.656 atm, the initial volume (V1) is 10.7 L. The new volume (V2) given is 13.1 L, there is a need to find the new pressure of the gas (P2).

Now putting the values in the above equation we get,

0.656 atm * 10.7 L = P2 * 13.1 L

P2 = 0.656 atm*10.7 L/13.1 L

P2 = 0.536 atm
