Explanation:
Because the solution only contains Na+ and Cl− ions, and water, and not the metal Na(s) . You cannot evaporate the water from the solution and hope to obtain anything but NaCl(s) .
.
Na(s) has an electron configuration of 1s^2 2s^2 2p^6 3s^1 , but Na+(aq) has an electron configuration of 1s^2 2s^2 2p^6 . That means they are not the same element, and thus, there is no straightforward way of extracting Na(s) from a NaCl (aq) solution
Answer:
6moles of water
Explanation:
Given parameters:
Number of moles of oxygen = 3moles
Reaction equation:
2H₂ + O₂ → 2H₂O
Unknown:
Number of moles of water formed = ?
Solution:
To solve this problem;
compare the number of moles in the reaction.
1 mole of oxygen gas will produce 2 mole of water
3 moles of oxygen gas will produce 3 x 2 = 6moles of water.
Explanation:
divide the objects weight by the acceleration of gravity to find the mass
Answer : 17.12 g
Explanation:
= elevation in boiling point
= boiling point elevation constant
m= molality

given 
Molar mass of solute = 46.0 
Weight of the solvent = 150.0 g = 0.15 kg
Putting in the values


x = 17.12 g
