Is filling a balloon with hot air a chemical or physical change?
Filling a balloon with hot air is a physical change because the hot air is simply expanding and occupying more space within the balloon, without any change in its chemical composition.
What happen when iron filling is heated with sulfur powder?
Heating iron filings with sulfur powder will result in a chemical reaction known as a thermite reaction. This reaction produces iron sulfide and a significant amount of heat and light. The iron sulfide formed is a black compound.
How can you tell if there is iron in a compound?
One way to determine if iron is present in a compound is through chemical tests such as the Prussian blue test, which forms a blue color in the presence of iron. Another method is using spectroscopic techniques like UV-Vis or X-ray fluorescence to detect the characteristic absorption/emission lines of iron atoms in the compound. Analysis using techniques such as atomic absorption spectroscopy or inductively coupled plasma mass spectrometry can also provide quantitative information about the iron content in a compound.
How can space filling molecular models be utilized in the study of chemical structures and interactions?
Space filling molecular models are used in the study of chemical structures and interactions to provide a visual representation of how atoms are arranged in a molecule and how they interact with each other. These models help scientists understand the spatial relationships between atoms, the overall shape of the molecule, and how different molecules can interact with each other based on their shapes and sizes. By using space filling models, researchers can better predict and analyze the behavior of molecules in various chemical reactions and processes.
How many covalent bonds normally associated with a single carbon atom in a compound?
A single carbon atom in a compound typically forms four covalent bonds. This allows carbon to achieve a stable electron configuration by filling its valence shell with a total of eight electrons.
Is filling a balloon with hot air a chemical or physical change?
Filling a balloon with hot air is a physical change because the hot air is simply expanding and occupying more space within the balloon, without any change in its chemical composition.
What is joint compound related to emulsion paint?
There is no relationship. -Joint compound is a plaster derivative for filling holes and emulsion (or latex) paint is only for painting and has no void filling function.
What is the pie filling in a pie a mixture or compound?
the inside of a pie, be it fruit, meat, or something else
Is balloons filled with helium a chemical change?
A balloon is filled with helium. Athough, it can be a chemical and physical change. For example you can take the helium out of the balloon, but you cant put it back in it now that its already in the air.
What is the best method for filling in a hole in drywall?
The best method for filling in a hole in drywall is to use spackling compound or joint compound to fill the hole, smooth it out with a putty knife, let it dry, sand it down, and then paint over it to match the surrounding wall.
Can i skim plywood with cement as a filling compound?
There are cements for this purpose specifically. Contact a flooring supply store.
What happens when you heat iron filling and sulfur was new substance formed?
Forms the compound, iron sulfide.
What is the difference between solid fuels and liquid fuels with suitable examples?
The difference will be in their physical state i.e., solid and liquid state and in their chemical composition. Solid fuels that are used are the filling inside bombs i.e,. gun powder. Liquid fuels used are RDX etc.
What is the best drywall gap filler to use for filling gaps between drywall sheets?
The best drywall gap filler to use for filling gaps between drywall sheets is joint compound.
When you are filling your gas tank and some spills out but soon dsapears physical or chemical change?
Physical
How do you compound feed for broilers and layers?
Compound feed is food for domestic animals that is made from a variety of sources and contains other additives. It can be fed to animals using either a broiler or a layer feeder, by filling the feeder up with the compound feed.
A man filling his car with gas is expecting what kind of energy conservation to happen?
Chemical potential energy
