What are the chemical composition for gold dust and chemical formula?
Assuming your gold is pure : Chemical composition = Au Chemical formula = Au
Is making chalk dust a chemical change?
No, it is a physical, not chemical change.
Are filtering air to remove dust and pollen a physical and chemical change?
Filtering air to remove dust and pollen is a physical change. This is because the process does not alter the chemical composition of the air or the dust/pollen particles. Instead, it simply separates the particles based on their physical properties.
What is formula of dust particle?
The formula of a dust particle can vary depending on its composition. Common components of dust particles include silicates, metals, and organic matter. However, there isn't a specific chemical formula for dust particles as they are typically a mixture of various substances.
The dust particles have exactly the same chemical composition as the gases of the interstellar medium?
Dust particles in the interstellar medium are made up of a variety of elements such as carbon, oxygen, silicon, and iron, similar to the composition of the gas. However, the dust particles can also contain complex molecules and compounds that are not present in the gas phase. Additionally, the physical and chemical properties of the dust particles can vary depending on their size, shape, and location within the interstellar medium.
Is filtering air to remove dust and pollen a physical or chemical change?
Filtering air to remove dust and pollen is a physical change because the process does not alter the chemical composition of the dust and pollen particles. It simply separates them from the air through physical means, such as using a filter.
Is a mud dries and change to dust a physical or chemical?
Physical.
What is the composition of a comet?
The composition of a comet is frozen gases, dust, and rocks.
Was there ever a problem with chemical dust in Milwaukee, WI?
Chemical Reactions in Metabolic Processes and were ever-present as household dust which was the problem with chemical dust
Is coal dust chemical or a physical toxicant?
Coal dust is considered a physical toxicant because it can cause harm through its physical properties, such as being inhaled and causing respiratory issues or skin irritation. Chemical toxicants, on the other hand, refer to substances that cause harm due to their chemical properties or composition.
When water evaporates its chemical composition?
The chemical composition remain unchanged.
How many m3 of flue gases?
The volume of flue gases can vary depending on the source and composition of the gases. However, to calculate the volume in cubic meters (m3), you would need to know the temperature, pressure, and composition of the flue gases, as well as the flow rate in cubic meters per second (m3/s). This information is typically provided in engineering specifications or can be measured using appropriate instruments.
