CaCO₃ + 2HCl  → CaCl₂ + H₂CO₃

While,

A + B → AB

Synthesis reaction:

It is synthesis reaction. The reaction in which two or more simple substance react to give one or more complex product.

AB → A + B

Decomposition:

polet [3.4K]

Answer:

Explanation:

Using Dalton's law of partial pressure

P total pressure = Pressure of helium + Pressure of neon + Vapor pressure of water

P = 28.3 mmHg, Pressure of helium = 381 mmHg, Vapor pressure of water at 28°C

791 mmHg - 381 mmHg - 28.3 mmHg = Pressure of neon

Pressure of neon = 381.7 mmHg
