Which of the following is not an acid-base neutralization reaction?
Alexus [3.1K]
A neutralization process is a reaction between an acid and a base which yields a salt and water. From the choices, a neutralization reaction would be: 2 HBr + Ca(OH)2 yields CaBr2 + 2 H2O.  Moreover, <span>NH3 + HCl yields NH4Cl is also a neutralization reaction. The complete reaction is actually NH4OH + HCl --> NH4Cl + H2O. NH4OH is the aqueous solution of NH3. This reaction is still a neutralization reaction.

On the other hand, the reaction </span><span>HCl + HBr yields H2 + ClBr is not valid. There is no reaction between HCl and HBr because both are strong acids. They would just dissociate into ions like H+, Cl- and Br-.

The valid reaction that is clearly not a neutralization process is </span><span>H2 + Br2 yields 2 HBr. This is a combination reaction yielding a strong acid HBr.</span>

Cylinders of compressed gas are typically filled to a pressure of 200 bar. For oxygen, what would be the molar volume at this pr
mars1129 [50]

Answer:

a

 V  =   0.124 \ Liters

b

V  =  0.112 \  Liters

Explanation:

From the question we are told that

  The pressure of compressed gas is P  =  200 \  bar = \frac{200}{1.013}=  197.4 \ atm

  The  temperature is  T  =  25^oC =  25 + 273 = 298 \  K

Generally the perfect gas equation is mathematically represented as

     PV =  nRT

substituting 0.08206 L-atm/mol-K  for R and  1 mole for n

We have that

     V  =  \frac{1 *  0.08206 * 298 }{ 197.4}

       V  =   0.124 \ Liters

Generally the van der Waals equation is mathematically represented as

       nRT  =  [P + \frac{n^2 * a }{V^2 } ][V - nb]

=>1 *  0.08206 *298  =  [197.4 + \frac{1^2 *  1.364}{V^2 } ][V - 1 * 3.19 * 10^{-2}]

=>    V  =  0.112 \  Liters
