Answer:

Explanation:

For amount of radiation from a hot body there is Stefan's Boltzman's law which is given below .

E = e σ T⁴

E is amount emitted , e is emissivity , σ is stefan's constant = 5.67 X 10⁻⁸ W / m² . for earth e =.85 approx

E = .85 x 5.67 X 10⁻⁸ x T⁴

604 = .85 x 5.67 X 10⁻⁸ x T⁴

604 = 4.82 x 10⁻⁸ T⁴

T⁴ = 125.31 x 10⁸

T =  3.3457 x 10²

= 334.57K

Temperature in Celsius = 334.57 - 273

= 61.57 Celsius .

If 3. 5 grams of ni are reacted with excess oxygen to form nickel oxide unser standard state conditions, what is the entropy cha
Mashutka [201]

Entropy Change is the measure of the randomness of the thermodynamic system. The entropy change for the reaction is -49.3 J/K.

<h3>What is the change in entropy?</h3>

Entropy change is the ratio of the heat transfer of the system to the absolute temperature of the system.

The entropy of nickel = 182.1 J/mol. K

The entropy of oxygen = 205.0 J/mol. K

The entropy of nickel oxide = 37.99 J/mol. K

Entropy change is calculated as:

\begin{aligned}\Delta \rm S &= 2(37.99)-2(182.1)-205\\\\&= 75.98 - 364.2 - 205\\\\&= -493.22 \end{aligned}

Therefore, -49.3 J/K is the entropy change.
