Answer:
The value of Kc is 660 (Option E) is correct
Explanation:
Step 1: Data given
Kp = 27
Temperature = 25.0 °C
Step 2: The balanced equation
2 NO(g) + Br2(g) ⇄ 2 NOBr(g)
Step 3: Calculate Kc
Kp = Kc * (RT)^Δn
⇒ with Kp = 27
⇒ with Kc = TO BE DETERMINED
⇒ with R = the gas constant = 0.08206 L*atm/mol*K
⇒ with T = The temperature = 25 °C = 298 K
⇒ Δn = the difference in moles = -1
27 = Kc * (0.08206*298)^-1
Kc = 660
The value of Kc is 660 (Option E) is correct

Answer:
NaHCO3 + HCl --> NaCl + CO2 + H2O
Explanation:
NaHCO3 which is an acidic salt because of the replaceable H+ (Bronste lowry acid), by definition acid dissociates in water to release a proton.
NaHCO3 dissociates in water to give Na+, H3O+ and HCO3-
Stomach acid which is HCl also dissociates in water to give H3O+ and Cl-
The H3O+ and HCO3- combines briefly to form a weak carbonic acid almost immediately, which then further dissociates to form H2O and CO2. CO2 is burped out from the mouth.
Na+ and Cl- combines to form NaCl in water which is a table salt solution.
