Which compound could serve as a reactant in a neutralization reaction? (1) nacl (3) ch3oh(2) koh (4) ch3cho

(2)

Explanation: When an acid reacts with the base then it undergoes neutralization to form a salt and water.

An acid is a substance that ionizes in the water to give hydrogen ion and have pH less than 7.

A base is a substance that ionizes in the water to give hydroxide ion and has pH more than 7.

Thus being a base can be a reactant in neutralization reaction.

being a salt can be a product in a neutralization reaction.

in the given question, the partial pressure is calculated by using the ideal gas equation, that is, pv = nrt

here, p is pressure, v is volume = 25 l, n is number of moles = 0.0104 moles, r is gas constant = -0.0821 l.atm / mol.k

t is temperature = 273 k

p = nrt / v

p = (0.0104 mol × 0.0821 l.atm / mol.k × 273 k) / 25 l

= 0.0093 atm
