On September 27, 2015, a rare total lunar eclipse of a supermoon occurred. A supermoon occurs when the entire lighted half of the Moon faces Earth (full Moon phase) and the Moon is at its closest point to Earth in its orbit.
Its a 3.0m solution so 1 litre of solution contains 3 moles of NaOH, 250ml of solution contains 0.25x39.9971 g/mol, so 250ml of this solution contains 0.75x39.9971=29.99g, or if you round it up 30.0g
If ion charges <u>decreases</u> then less attraction and energy <u>decreases</u>.
If radii <u>increases</u> then there is more distance , less attraction result of this energy <u>increases </u>
so energy increases as ion charges increases and radii decreases
Answer: 7.29 g of 
will be produced from the given masses of both reactants.
Explanation:
To calculate the moles :
According to stoichiometry :
1 mole of 
require = 8 moles of 
Thus 0.0267 moles of will require=
of
Thus is the limiting reagent as it limits the formation of product and is the excess reagent.
As 1 mole of give = 8 moles of
Thus 0.0267 moles of give = of
Mass of 
Thus 7.29 g of will be produced from the given masses of both reactants.
The solutions vapor pressure would be lower.
