Answer:

(True) The answer to that is yes, global warming is a hotly debated topic.

Explanation:

As a matter of political controversy, global warming is often viewed from different political perspectives. Which is why it is still an issue. (In 1988, global warming became a topic of discussion.) A number of climate change-related phenomena are occurring due to climate change, including rising temperatures, droughts and wildfires, changing precipitation patterns, glaciers melting, and rising sea levels.

Hope this helps! :D

4Fe (s) + 3 O2 (g) → 2 Fe2O3 (s)
Novay_Z [31]

Explanation:

The number acquired by an element after the lose or gain of an electron is called oxidation number.

For example, 4Fe(s) + 3O_{2}(g) \rightarrow 2Fe_{2}O_{3}(s)

Here, oxidation number of Fe(s) is 0 and Fe in Fe_{2}O_{3} is +3.

Oxidation number of O in O_{2}(g) is 0 as it is present in its elemental state.

The oxidation number of O in Fe_{2}O_{3} is calculated as follows.

2(3) + 3x = 0\\6 + 3x = 0\\x = \frac{-6}{3}\\= -2

Hence,  oxidation number of O in Fe_{2}O_{3} is -2.

  • The loss of electrons by an element or substance is called oxidation. Here, electrons are being lost by Fe(s) as an increase in oxidation state is occurring. So, Fe(s) is oxidized.
  • The gain of electrons by an element or substance is called reduction. Here, electrons are being added to O_{2} as a decrease in its oxidation state is occurring. So, O_{2}  is reduced.
  • An element or compound which is being reduced is called oxidizing agent. Here, O_{2}  is the oxidizing agent.
  • An element or compound which is being oxidized is called reducing agent. Here, Fe(s) is the reducing agent.

The energy gap between the valence band and the conduction band in the widely-used semiconductor gallium arsenide (GaAs) is Δ =
stira [4]

Answer:

n_e = 8.139 *10^6

Explanation:

Given that;

The energy gap between the valence band and the conduction band in the widely-used semiconductor gallium arsenide (GaAs) is Δ = 1.424 eV.

So; that implies that:

\delta \ E = 1.424 \ eV

Suppose that we consider a small piece of GaAs with 1020 available electrons, -- This is taking about the numbers of electrons used which is :

n_i = 10^{20} \ electrons

Temperature is given as:

T = 274.15 \ K

Number of electrons can be calculated by using the formula;

n_e = n_i*e^-^{\frac{\delta E }{2 K_B*T}}

n_e = 10^{20}*e^-^{\frac{1.424}{2*8.617*10^{-5}*274.15}}

n_e = 8.139 *10^6
