(4.5 x 50)/(n x 273) = (1 x 22.4)/(1 x 273)
n = (4.5 x 50)/(22.4) = 10.04 moles

This is not a common reaction at standard temperature and pressure.
Both ammonia and hydrochloric acid are colorless gases at standard temperature and pressure, but they are capable of reacting with each other to produce ammonium chloride, which is a white solid at standard temperature and pressure. Colorless gases are invisible to human eyes, but white solids are not. When the two gases diffuse toward one another, they form finely divided white solids that remain visible for a while as a white ring in the diffusion interface.
1 mole of sodium carbonate + 2 moles of Hydrochloric acid would produce 1 mole of Carbon Dioxide which would occupy 22.4 liters at standard temperature and pressure
You can use the pencil to stir the water and produce a whirlpool in the container
The pressure

Pressure and heat.
The air pressure over the continent may be heavy or less. The changes in temperature only produce pressure and the temperature change with seasons.
It depends of the volume of the container. When the container is the atmosphere there's no practical amount. In a confined volume of a single cubic meters at standard pressure a handfull of briquettes 2-3 I would think should suffice. Grade intermediate volumes accordingly.
Nothing, It will sink but it won't react with water at room temperature. You have to heat graphite to something like 800 degrees Celsius to react with water at that temperature it will react with steam to produce carbon monoxide and hydrogen gas.
Sodium reacts with water at room temperature (even at lower ) and produce hydrogen gas , 2Na + 2H2O = 2NaOH + H2
Apply the Ideal Gas Law :PV = nRTn = ( P ) ( V ) / ( R ) ( T )n = ( 407.1 mm Hg ) ( 50 L ) / ( 62.37 mm Hg - L / mol - K) ( 273.2 K )n = 1.195 mole

A tire pressure monitoring system may produce a warning if the tire pressure is too high or too low. High pressure may cause the tire to explode or fail in hot temperature. Low tire pressure causes the tire to break down more easily.
It depends on the pressure of the system that the water is in. In atmospheric pressure (ie at sea level and in the open) water turns into steam at 100 degrees Celsius. At higher pressures this temperature decreases.
