How much sodium chloride is produced from the synthesis of 100g of sodium and an excess of chlorine gas? 2Na + Cl2= 2NaCl

254.35 g of NaCl.

Explanation:

We'll begin by writing the balanced equation for the reaction between sodium (Na) and chlorine (Cl₂) to produce sodium chloride (NaCl). This is illustrated below:

2Na + Cl₂ —> 2NaCl

Next, we shall determine the mass of Na that reacted and the mass of NaCl produced from the balanced equation. This can be obtained as follow:

Molar mass of Na = 23 g/mol

Mass of Na from the balanced equation = 2 × 23 = 46 d

Molar mass of NaCl = 23 + 35.5

= 58.5 g/mol

Mass of NaCl from the balanced equation = 2 × 58.5 = 117 g

SUMMARY:

From the balanced equation above,

46 g of Na reacted to produce 117 g of NaCl.

Finally, we shall determine the mass of NaCl produced by the reaction of 100 g of Na. This can be obtained as follow:

From the balanced equation above,

46 g of Na reacted to produce 117 g of NaCl.

Therefore, 100 g of Na will react to produce = (100 × 117)/46 = 254.35 g of NaCl.

Thus, 254.35 g of NaCl were obtained from the reaction.

under a microscope, cancer cells may look very different from normal cells. they often have different sizes and some may be larger than normal while others are smaller. cancer cells are often abnormally shaped and the control centre of the cell (the nucleus) may have an abnormal appearance.
