Research the Greenhouse effect and how it relates to heat transfer.

Chemistry
1 answer:
julsineya [31]2 years ago
6 0

Answer:

The greenhouse effect is a phenomenon of radiative transfer, the process by which the energy of light waves is exchanged in matter. Radiative transfer dictates what energy is reflected, absorbed, and emitted. The greenhouse effect: A summary of the heat transfer in the Earth's atmosphere

Which of the following reactions are redox reactions? 4Li(s)+O2(g)→2Li2O(s) Zn(s)+Cu2+(aq)→Zn2+(aq)+Cu(s) Sr(NO3)2(aq)+Na2SO4(aq
Lapatulllka [165]

Answer:  

As2O3 → H3AsO4

As2O3 → 2H3AsO4             balance As

5H2O + As2O3 → 2H3AsO4       balance O by adding H2O to one side

5H2O + As2O3 → 2H3AsO4 + 4H+    balance H by adding H+ to one side

5H2O + As2O3 → 2H3AsO4 + 4 H+ + 4e-     balance charge by adding electrons to one side

 

Now do the same for the other part of the reaction

NO3- → NO

NO3- → NO + 2H2O

4H+ + NO3- → NO + 2H2O

3e- + 4H+ + NO3- → NO + 2H2O

 

Now cancel the electrons by multiplying the first equation by 3 and the second equation by 4, then add them together .

 

3As2O3 + 4NO3- + 7H2O + 4H+ → 6H3AsO4 + 4NO

For the reaction: N2(g) + 2 O2(g) ⇌ 2 NO2(g), Kc = 8.3 × 10-10 at 25°C. What is the concentration of N2 gas at equilibrium when
KATRIN_1 [288]

Answer: Concentration of N₂ is 4.8.10^{9} M.

Explanation: K_{c} is a constant of equilibrium and it is dependent of the concentrations of the reactants and the products of a balanced reaction. For

N2(g) + 2 O2(g) ⇄ 2 NO2(g)

K_{c} = \frac{[NO2]^{2} }{[N2][O2]^{2} }

From the question concentration of NO2 is twice of O2:

[NO2] = 2[O2]

Substituting this into K_{c}:

K_{c} = \frac{[2O2]^{2} }{[N2][O2]^{2} }

8.3.10^{-10} = \frac{4O2^{2} }{[N2].O2^{2} }

[N2] = \frac{4O2^{2} }{8.3.10^{-10}.O2^{2}  }

[N2] = \frac{4}{8.3.10^{-10} }

[N2] = 4.8.10^{9}

The concentration of N2 in the equilibrium is [N2] = 4.8.10^{9}M.
