Dissolving the sugar cube in water is a physical change. It doesn't alter the sugar's chemical structure like burning it or breaking it down with acid.
You don’t feel like you have to hide anything from your parents so you can share things with them easily.
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:
nutrient
Explanation:
In other words, nutrients provide our bodies with feedback for how to work, and diet can be used as a 'information' source for the organism. if the ingestion of nutrients is not regularly fulfilled to fulfill the cell function nutritional requirements, the metabolism processes slow down or even cease.'
