The balanced molecular equation for the reaction between solid sodium bicarbonate and hydrochloric acid to produce carbon dioxide gas, water and aqueous solution of sodium chloride is
<h3>NaHCO₃(s) + HCl(aq) —> CO₂(g) + H₂O(l) + NaCl(aq) </h3>
The balanced equation can be written as follow:
Sodium bicarbonate => NaHCO₃
Hydrochloric acid => HCl
Carbon dioxide => CO₂
Water => H₂O
Sodium chloride => NaCl
Sodium bicarbonate + Hydrochloric acid —> Carbon dioxide + Water + Sodium chloride
<h3>NaHCO₃(s) + HCl(aq) —> CO₂(g) + H₂O(l) + NaCl(aq) </h3>
The equation above is balanced since the number of the different atoms of the elements present on both sides are equal.

Answer:1
Explanation:i hope u have a wonderful night and stay safe
PV=nRT
p = 1,5atm = 1,5*101325 = 151987,5 Pa
V = 11,9l = 0,0119m3
n = ?
R = 8,314 J/mol*K
T = 20°C = 20+273 = 293K
pV=nRT
151987,5*0,0119 = n*8,314*293
1808,6513=n*2436,002 ||:2436,002
0,7425 = n >>> moles of CO2
1 mole of CO2 = 44g
1 mole of CO2--------------44g
0,7425 moles of CO2----------x
<u>x = 32,67g of CO2</u>
Answer:
Explanation:PRESSURE: atmospheres or mm Hg; 1 atm = 760 mm Hg
TEMPERATURE: Kelvin, K, which is o
C + 273
STP: Standard Temperature and Pressure: 273 K and 1 atm (or 760 mm Hg)
BOYLE'S LAW (temperature is constant): PV = constant
This is an inverse relationship: if one variable increases the other must
decrease.
CHARLES' LAW (pressure is constant): V = constant x T
This is a direct relationship: if one variable increases so does the other.
GAY-LUSSAC'S LAW (volume is constant): P = constant x T
This is a direct relationship: if one variable increases so does the other.
<h2>Every one of this with the constant</h2>
