K = 39 g/mol
KNO3 = 101 g/mol
2 KNO3 + 10 K = 6 K2O + N2
2 x 101 g KNO3 ---------- 10 x 39 g K
122 g KNO3 -------------- ??
122 x 10 x 39 / 2 x 101 =
47580 / 202 => 235.54 g of K
( KNO3 is Excess reagent )
2 x 101 g KNO3 ---------- 10 x 39 g K
?? --------------------------- 155 g K
155 x 2 x 101 / 10 x 39 =
31310 / 390 => 80.28 g of KNO3 ( K is <span>limiting reagent )

hope this helps!

Chemical reaction: NaHCO₃ + HCl → NaCl + CO₂ + HCl.
Reaction occurs between sodium bicarbonate (sodium hydrogen carbonate) and hydrochloric acid. For example, hydrogen carbonate<span> mixed with water is used like </span>antacid (neutralizes <span>stomach acidity), contverts </span>stomach acid (hydrochloric acid) to carbon dioxide.
