A covalent bond is formed by D) Gaining or losing two or more electrons by an atom.
Hope this helps!
deposition- gas to solid
sublimation- solid to gas
Answer:
2.34g of NaCl
Explanation:
HCl(aq) + NaOH(aq) --------> NaCl(aq) + H2O(l)
Number of moles of HCl= 8 × 5/1000= 0.04 moles
Number of moles of NaOH= 2.4 × 20/1000= 0.048 moles
HCl is the limiting reactant
From the balanced reaction equation, 1 mole of HCl produced 58.5g of NaCl
0.04 moles of HCl will produce 0.04 × 58.5 = 2.34g of NaCl
Supersaturated solutions hold more of the solute at higher temperatures than they would at room temperature. Hence, the correct answer would be that the water would need to be heated to a higher temperature, which would give molecules and ions more kinetic energy, increasing solubility.
Generally, solubility increases with increase in temperature. At higher temperature, the kinetic energy of molecules in solution increase. Consequently, more of the molecules/ions of solutes collide more with each other and dissolve. At lower temperature, the molecules of the solutes crystalize out in solution.
