It has to be below freezing in order for the snow to fall.
The correct answer is 2.99 helium atoms.
I hoped this helped!
Answer:
Reactive and lose 1 electron
Explanation:
Depends if the reaction is endo or exo thermic
Endothermic reaction
Increasing the temperature will shift the equilibrium to the right-hand side of the equilibrium. to oppose the change in temperature.
Exothermic reaction
Increasing the temperature will shift the equilibrium to the left-hand side of the equilibrium. to oppose the change in temperature.
Hope that helps
Here we have to get the amount of heat will generate by 510.0 kg of sodium sulfate decahydrate at night assuming complete reaction and 100% efficiency of heat transfer.
510.0 kg of sodium sulfate decahydrate will produce 5.603 × 10⁵ kJ of heat energy.
The molecular weight of sodium sulfate decahydrate (H₂₀Na₂O₁₄S) 322.186 g/mol.
Thus 510.0 kg of H₂₀Na₂O₁₄S is equivalent to = 1582.936 mol of H₂₀Na₂O₁₄S.
Now per mole of H₂₀Na₂O₁₄S will transfer 354 kJ heat.
Thus 1582.936 mol will transfer 1582.936 × 354 kJ = 5.603×10⁵ kJ of heat.
Henceforth, 510.0 kg of sodium sulfate decahydrate will produce 5.603 × 10⁵ kJ of heat energy.
