Which answer below correctly identifies the type of change and the explanation for the heating of copper sulfate pentahydrate?
Which answer below correctly identifies the type of change and the explanation for the heating of copper sulfate pentahydrate?
Which answer below correctly identifies the type of change for heating copper of sulfate pentahydrate? Chemical change because gas formation observe along with a color change, which indicated that the copper sulfate pentahydrate was transformed into a different substance.
Which answer below correctly identifies the type of change and the explanation for the change in calcium?
The type of change and the explanation for the change in calcium carbonate would be that it is a physical change because even though a particle size change was observed, the calcium carbonate retained its original properties and was not transformed into a new substance.
Which answer below correctly identifies the type of change and the explanation for the separation of the iron with sulfur physical change because even though a color change occured each solid maintained its original properties which could be seen as soon as the magnet was applied physical change because?
Explanation: Physical change because even though a color change occured, each solid maintained its original properties, which could be seen as soon as the magnet was applied. Speration of iron with sulfur will not change the properties of the metals, the magnet can be used to check.
What type of change is boiling?
Boiling waterBoiling water is an example of a physical change and not a chemical change because the water vapor still has the same molecular structure as liquid water (H2O). If the bubbles were caused by the decomposition of a molecule into a gas (such as H2O →H2 and O2), then boiling would be a chemical change.
Which states can flow?
Solids, liquids and gases are called the three states of matter….Liquids
- Liquids can flow or be poured easily.
- Liquids change their shape depending on the container they are in.
What can flow in all directions?
Answer. The particles in a gas move quickly in all directions, but they do not get far before they bump into each other or the walls of their container. If the temperature is increased, the particles in a gas move faster, so they hit the walls of the container more often. This causes the pressure to rise.
Can liquids flow in all directions?
A liquid is made up of tiny vibrating particles of matter, such as atoms, held together by intermolecular bonds. Like a gas, a liquid is able to flow and take the shape of a container. Unlike a gas, a liquid does not disperse to fill every space of a container, and maintains a fairly constant density.
Why do gases flow in all directions?
The attractive forces between the particles in a gas are very weak, so the particles are free to move in any direction.
Why gases can flow easily?
The atoms and molecules in gases are much more spread out than in solids or liquids. They vibrate and move freely at high speeds. A gas will fill any container, but if the container is not sealed, the gas will escape. Gas can be compressed much more easily than a liquid or solid.
What is a gas particle?
Gases consist of particles (molecules or atoms) that are in constant random motion. Gas particles are constantly colliding with each other and the walls of their container. These collisions are elastic; that is, there is no net loss of energy from the collisions.
What is the main difference between solid liquid and gas?
Solids have a definite shape and volume. Liquids have a definite volume, but take the shape of the container. Gases have no definite shape or volume.
Is air a gas?
Air is mostly gas It’s a mixture of different gases. The air in Earth’s atmosphere is made up of approximately 78 percent nitrogen and 21 percent oxygen. Air also has small amounts of lots of other gases, too, such as carbon dioxide, neon, and hydrogen.
