1.9 mol hcl and 3.9 mol naoh react according to the equation hcl + naoh −→ nacl + h2o . if the limiting reactant is hcl, calculate the amount of nacl formed.

According to the molar ratio in the equation, for every 1 mole of HCl, 1 mole of NaCl is formed.

Thus, if 1.9 mol of HCl is used up in the reaction, 1.9 mol of NaCl is formed.

So the answer is 1.9 mol of NaCl.

answer:

technetium is the most reactive. this is followed by silver. the least reactive out of these three elements is strontium.
