Nuclear fusion:
in this nuclear reaction two or more atoms of same of different elements combine to form atom of new element.
Here in the third image (as mentioned in the figure) two atoms are combining to from a new element with elimination of a small nuclear particle (like neutron or energy particle) .
Hence in image nuclear fusion is taking place.
Answer:
The Gibbs free energy is -2997.83 kJ mol-1.
Explanation:
The change in Gibbs free energy of the reaction can be calculated using the formula.
WHere R = Gas constant = 8.314KJ/Kmol
T = the temperature of the reaction in Kelvin = (37.0 + 273) = 310K
K = Raio of molar concentration of the two reactants = 1.6/0.5 = 3.2
Therefore,
Therefore the Gibbs free energy is -2997.83 kJ mol-1.
The negative sign indicates that the reaction is spontaneous.
Answer: Increases.
Explanation: As the temperature of a liquid or solid increases its vapor pressure also increases. Conversely, vapor pressure decreases as the temperature decreases.
Answer: 1560632 joules
Explanation:
The change in thermal energy (Q) required to heat ice depends on its Mass (M), specific heat capacity (C) and change in temperature (Φ)
Thus, Q = MCΦ
Given that:
Q = ?
Mass of frozen water (ice) = 1kg
C = 4184 J/(kg K)
Φ = (Final temperature - Initial temperature)
= 100°C - 0°C = 100°C
Convert 100°C to Kelvin
(100°C + 273) = 373K
Then, Q = MCΦ
Q = 1kg x 4184 J/(kg K) x 373K
Q = 1560632 joules
Thus, the change in thermal energy is 1560632 joules
