Identity the place which has the highest boiling of water Death valley, 282 feet

Question

Identity the place which has the highest boiling of water Death valley, 282 feet below sea level Mt. Everest, 29, 035 feet New Orleans, sea level A pressurized passenger jet, 35,000 feet Denver, Colorado, 5280 feet Give the net ionic e for the reaction (if any) that occurs when aqueous solutions of Na_2CO_3 and HCl are mixed. 2H^+(aq) + CO_3^2-(aq) rightarrow H_2CO_3(s) 2 Na^+ (aq) + cO_3^2-(aq) + 2 H^+ (aq) + 2 Cl^-(aq) rightarrow H_2CO_3(s) + 2 NaCl(aq) 2 H^+ (aq) + CO_3^2- rightarrow H_2O(l) + CO_2(g) 2Na^+(aq) + CO_3^2-(aq) + 2H^+ 2 Cl^-(aq) rightarrow H_2CO_3(s) + 2 Na^+ (aq) + 2 Cl^-(aq) No reaction occurs. Determine the oxidizing agent in the following reaction. 2 Li(s) + Fe(C_2H_3O_2)_2(aq) rightarrow 2 LiC_2H_3O_2(aq) + Fe(s)

Explanation / Answer

As pressure is increased, the boiling point drops and liquid boils at lower temperature than atmoshperic pressure (at seal level). As we go down below the sea level, the pressure increases ans this also leads to an increase in boiling point of water. So accordingly, death valley will have more boiling point of water ( A is correct)

2.

The reaction Na2CO3(aq)+2HCl(aq)------>2NaCl(aq)+ H2O(l) +CO2(g) ( molecular reaction)

2Na++2CO3- + 2H+ +2Cl- --->2Na++2Cl- + H2O(l)+CO2(g) ( ionic reaction)

2H++2CO3- ------>H2O(l)+CO2(g) ( net ionic equation). C is correct.
