Does copper particles contain kinetic energy?
the particles in copper only have kinetic energy once it has been heated as this causes the particles to move around (kinetic energy) knocking its neighbour causing heat
Why copper can conduct elevtricity when solid or liquid but copperII sulphate can only conduct electricity if molten or aqueous?
Copper atoms have mobile electrons that can flow freely to conduct electricity in solid or liquid form. In copper(II) sulfate, the copper atoms are already bonded to sulfate ions, limiting the movement of electrons. When the compound is melted or dissolved in water, the copper atoms can dissociate from the sulfate ions, allowing for the flow of charged particles and therefore conducting electricity.
Write a word equation to describe the decomposition of copper on heating?
CuCO3 ==> CO2 + CuO (heat is the catalyst, written above the arrow)
What word is used to describe a mixture that is 85 percent copper and 15 percent tin?
The word used to describe a mixture that is 85% copper and 15% tin is bronze. Bronze is an alloy made by mixing copper and tin in various proportions to achieve different properties like increased durability and strength.
Why does copper sulfate change mass when heated?
Solid copper appears to gain mass when heated in air, because the copper reacts with oxygen in the air to form copper oxide. However, the actual mass of the copper does not increase; the mass of the solid increases by a value equal to the mass of oxygen removed from the air.
Which single term is used to describe the mixing of copper sulphate and water kept in a beaker on its own?
The term used to describe the mixing of copper sulphate and water in a beaker is "dissolution." This process involves the copper sulphate particles dispersing and mixing with the water to form a homogeneous solution.
What happens to the particles when you mix copper sulphate and iron?
Diffusion occurs - The particles of copper sulphate move between the particles iron because the particles are tiny and discrete.
What process obtain tiny particles copper sulphate from copper?
Crystallization
How does changing the initial mass of the copper affect how much energy it has?
Changing the initial mass of the copper will affect the total amount of energy the copper has. More mass means more particles requiring energy for movement and vibration, resulting in a higher total energy. Conversely, less mass will result in lower total energy due to fewer particles needing energy for motion.
Briefly explain why is bronze much harder that either copper or tin?
nether.tin is a rock
What happens to the particles in copper when heated by a Bunsen burner?
When copper is heated by a Bunsen burner, the particles gain energy and vibrate more rapidly. As the temperature increases, the particles may eventually gain enough energy to overcome the forces holding them together, allowing the copper to melt and eventually evaporate into copper vapor.
Does copper particles contain kinetic energy?
the particles in copper only have kinetic energy once it has been heated as this causes the particles to move around (kinetic energy) knocking its neighbour causing heat
Is the attraction between steel particles stronger than the attraction between copper particles?
yes
Why are particles close together?
The particles in copper are close together because it is a type of solid. Solids have a definite shape and mass. Copper is a type of metal, which is a great conductor. Any item with hardness is a solid, for copper is a solid
Are Ions copper?
Yes, copper ions are ions of the element copper. They are positively charged particles formed when a neutral copper atom loses one or more electrons.
When a crystal copper sulphate is placed at the bottom of a beaker contaning water the colour of water slowly becomes blue?
The spreading of blue colour of coppersulphate crystals in water is due to movement of water paticles as well as coppersulphate particles.due to the movement of particles the coppersulphate crystals and water particles mix with each other this is called diffusion.diffusion takes place untill the whole water obtain blue colour.
How does the energy of the energy of the particles in a certain amount of liquid copper compare to the energy of the molecules in the same amount of liquid water why?
The energy of particles in liquid copper is generally higher than the energy of molecules in liquid water because the metallic bonding in copper leads to stronger forces between the particles. These stronger forces result in higher energy required to break the bonds between the particles in copper compared to the weaker intermolecular forces in water.
