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.

True. because you can set realistic goals based on what you can do.
Explanation:
False
Prostate cancer does not usually display symptoms within its early stages of development- in early stages it's deemed as asymptomatic. This type of cancer grows very slowly and is usually limited to the region of the prostate gland=and some cancer types require no or minimal treatment while others grow and spread aggressively.
In later stages prostate cancer symptoms include bone pain, erectile dysfunction, pelvic discomfort, trouble with urination and blood found in the semen. men are at higher risk for prostate cancer development as they age, if they have a family history of prostate cancer or if they are obese.
