When copper powder and zinc powder are ground together...is the result a solution or a heterogeneous mixture?

oh and i know brass is an alloy (a solid solution) of copper and zinc


can you please explain why its a solution or a heterogeneous mixture in simple terms? thanks!When copper powder and zinc powder are ground together...is the result a solution or a heterogeneous mixture?
It would be a mixture just like mixing salt and pepper, unless you heated them and blended into an alloy. Copper and zinc won't react with each other, unless there is a lot of heat or some solvent involved to form a chemical bond.When copper powder and zinc powder are ground together...is the result a solution or a heterogeneous mixture?
When you grind the solids together, the result is a heterogeneous mixture. The components are mixed, but the individual particles still retain their own identity. This mixture will have the properties of both copper and zinc, because both individual metals are present.





In a solution, the components are completely mixed with each other, and they take on a new identity. The properties change as well. Brass has different properties than copper or zinc does, because they have interacted.





Hope that helps a bit.
It is a heterogenous mixture because the small peices are still uniquely copper and zinc.

When a penny is placed in zinc powder and 6.0 molar sodium hydroxide it gets a silvery appearance?

after it becomes silver and placed in a flame why does it get a gold appearance?!When a penny is placed in zinc powder and 6.0 molar sodium hydroxide it gets a silvery appearance?
it becomes silver then gold then sh*t

Can i make rocket propellent using zinc sulphate powder instead of zinc powder?

Very simply - no. Zinc is a reducing agent. Zinc sulphate is not.

How to obtain sodium sulphate from mixture of sodium sulphate contaminated with zinc powder?

i want to get pure and dry crystals from the experiment,please list down steps thanksHow to obtain sodium sulphate from mixture of sodium sulphate contaminated with zinc powder?
Sodium sulfate is water soluble, zinc is not. Add distilled or deionized water to the mixture to dissolve the sodium sulfate. Filter the mixture to remove the zinc. Evaporate the water from the sodium sulfate.

Why does zinc powder and 6.0 molar sodium hydroxide cause a penny to have a silvery appearance?

i need to write a hypothesis about it!Why does zinc powder and 6.0 molar sodium hydroxide cause a penny to have a silvery appearance?
My best guess is that you have created an electrolytic solution and plated zinc onto the surface of the penny.

What gas is released when lemon juice reacts with zinc powder?

Is it nitrogen gas or oxygen gas?What gas is released when lemon juice reacts with zinc powder?
Its not nitrogen, oxygen or CO2.





The gas released is Hydrogen.





Metal + acid -%26gt; salt + hydrogen








CO2 is released when:


metal carbonate + acid -%26gt; salt + CO2 + H2OWhat gas is released when lemon juice reacts with zinc powder?
Carbon dioxide.

Now you dont have to get off the couch when your Gf or wife wants you to do laundry.I invented a gun that propels powdered detergent up to 250 feet away?
If you skip doing laundry until your clothes are so in need of a cleaning that you can't even come near them without passing out from the odor, then you clearly need a way to apply detergent to them from 250 feet away.

Help them, soap those fountains and free some of that water to float back into the air in bubbles.
