The Errors for the setup or preparation of ammonia gas includes:
- inadequate temperature use
- absence of a catalyst
- inadequate pressure during preparation of the ammonia gas.
Ammonia gas is the hydride of nitrogen. In nature, this gas is produced when nitrogenous matter decays in the absence of air.
In the industrial preparation of ammonia gas, it is manufactured from nitrogen and hydrogen by the Haber process.
Since the direct combination between nitrogen and hydrogen is reversible, special conditions of reaction are necessary for the optimum yield of ammonia. These include:
- Catalyst: The presence of finely divided iron as a catalyst is necessary for the optimum yield of ammonia gas.
- Temperature: the Haber process requires the temperature of about 450°C for the optimum yield of ammonia gas
- Pressure: A pressure of about 200 atmospheres is required.

During the contraction of the left ventricle, the systemic arterial pressure reaches its maximum, which is called systolic pressure.
<h3>Generation of Blood pressure</h3>
The heart is the hollow muscular organ that is made up of four chambers which include:
As the heart contracts to pump blood to the entire circulation, it generates both the systolic and diastolic pressures.
The peak arterial pressure during the contraction of the left ventricle is called the systolic pressure. This leads to the pumping of blood to the general systemic circulation.
