Answer:
2993 °C
Explanation:
A reaction is spontaneous if the free Gibbs energy (ΔG) is negative. ΔG is related to the enthalpy of the reaction (ΔH) and the entropy of the reaction (ΔS) through the following expression.
ΔG = ΔH - T . ΔS
For 1 mol, if ΔG < 0, then
ΔH - T . ΔS < 0
ΔH < T . ΔS
-320.1 × 10³ J < T . (-98.00 J/K)
T < 3266 K
To convert Kelvin to Celsius we use the following expression.
K = °C + 273.15
°C = K - 273.15 = 3266 - 273.15 = 2993 °C
I think it’s a. the lithosphere
Answer:
39.2 N
Explanation:
1kg at the earth's surface has a force of 9.8 N acting on it.
(4 kg) (9.8N) = 39.2 N
