Answer:
Cl is more likely to than Na
Explanation:
The question asks for the element more take up an electron from the other
The ability of an atom to take take or give electrons in a chemical reaction, depends on its electron affinity and ionization energy, respectively
Chlorine, Cl, has the highest electron affinity in the periodic table which makes it attract electrons more towards itself
Sodium, Na, has a low ionization energy (about 2/5 of that of chlorine) than chlorine, Cl, making sodium more readily able to give its valence electron in a reaction
Therefore, Cl is more likely to take up an outer electron from Na.
(2) CH3COOH
(3)KCl
(3)KOH
NaOH + CH3COOH yields Na CH3COO + H2O
2HNO3 + Ca(OH)2 yields Ca(NO3)2 + 2H2O
H2SO4 + 2NaCl yields 2HCl + Na2SO4
(2) grams of NaCl per liter of solution
(3) moles of NaCl per liter of water
(4) moles of NaCl per liter of solution
Answer:
The correct option is (4)
Explanation:
Molarity (M) is generally defined as the number of moles of a solute per liter of the solution.
The formula for molarity (from the definition above) is
M = number of moles (n) ÷ volume (in liters or dm³)
The unit for molarity is mol/L or mol/dm³
From the above, it can be deduced that the molarity of an aqueous solution of common salt (NaCl) is the number of moles of NaCl per liter of the salt solution.
