Answer: 1090°C
Explanation: According to combined gas laws
(P1 × V1) ÷ T1 = (P2 × V2) ÷ T2
where P1 = initial pressure of gas = 80.0 kPa
V1 = initial volume of gas = 10.0 L
T1 = initial temperature of gas = 240 °C = (240 + 273) K = 513 K
P2 = final pressure of gas = 107 kPa
V2 = final volume of gas = 20.0 L
T2 = final temperature of gas
Substituting the values,
(80.0 kPa × 10.0 L) ÷ (513 K) = (107 kPa × 20.0 L) ÷ T2
T2 = 513 K × (107 kPa ÷80.0 kPa) × (20.0 L ÷ 10.0 L)
T2 = 513 K × (1.3375) × (2)
T2 = 1372.275 K
T2 = (1372.275 - 273) °C
T2 = 1099 °C
2Na + H₂ = 2NaH (sodium-hydride).
The thick soil accumulation of fine-grained particles is called as silt
Answer:
1.38269 amu
Explanation:
Gadolinium-157 has 64 protons and 93 neutrons. Recall that mass defect his the difference between the calculated mass and the actual mass of the atom. This difference in calculated mass and actual mass exists because some mass is converted to the binding energy of the nucleus.
Mass of 64 protons= 64 × 1.007825 = 64.5008 amu
Mass of 93 neutrons= 93 × 1.008665 = 93.805845 amu
Mass of neutrons and protons= 64.5008 + 93.805845 = 158.306645 amu
Mass defect= 158.306645 - 156.92396 = 1.38269 amu
Therefore, mass's defect of gadolinium-157 is 1.38269 amu
