The Law of Conservation of Mass states "Mass cannot be created or destroyed, only transformed."
Considering the Law of Conservation of Mass, 4 grams of Sodium (Na) will need to combine with how many grams of Cl (Chlorine) to produce 10 grams of Sodium Chloride?

To determine the answer, we need to calculate the mass of chlorine (Cl) required to form 10 grams of sodium chloride (NaCl) using the Law of Conservation of Mass.
Sodium chloride (NaCl) is formed by the combination of one sodium atom (Na) with one chlorine atom (Cl). The atomic masses of Sodium and Chlorine are approximately 23 grams/mol and 35.5 grams/mol, respectively.
For 10 grams of sodium chloride, we need to determine the number of moles of NaCl and then multiply it by the molar ratio of NaCl to Cl.
Molar mass of NaCl = 23g/mol (Na) + 35.5g/mol (Cl) = 58.5g/mol (NaCl)
Number of moles of NaCl = mass/molar mass = 10g / 58.5g/mol = 0.17 mol
From the balanced equation, we know that for every 1 mole of NaCl formed, we need 1 mole of Cl. Therefore, the number of moles of Cl needed is the same as the number of moles of NaCl.
Moles of Cl = 0.17 mol
Now, we can calculate the mass of chlorine needed to form 10 grams of sodium chloride.
Mass of Cl = moles of Cl x molar mass of Cl = 0.17 mol x 35.5g/mol = 6.0 grams
Therefore, the answer is 6 grams.
