They time how long each can hold it up above their heads for, then compare the times. The longest time has the most endurance.
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.

Answer:
Erickson speaks of faith, will and intention as the values of multiple periods of life. He gave an eight-stage features of individual growth through infancy until death. He stated that a confrontation characterises each period of development and if this disagreement is settled effectively, the person will evolve as a virtuous person. The 'confidence vs. mistrust' is regarded as his first period in life.
The increasing person creates schemes about the capabilities he has after the effective accomplishment of each phase of life. If the substantial others take charge of the phases of life quite well, so the principles of that phase are established in him.
Did you mean mechanical ? If you do mean mechanical then here's the answer to your question:
Mechanical digestion is when the food is being broken down physically into smaller pieces from the mouth and chemical digestion is when the food is being broken down into substance particals starting from the saliva and proceeding through the small intestines.
