Is quartz harder than copper?
Based on Moh's Scale of Hardness that identifies minerals, it is. Moh's Scale of HardnessTalcGypsumCalciteFluoriteApatiteOrthoclaseQuartzTopazCorundumDiamondIn this scale, 10 minerals are used as reference. These minerals are arranged from the softest (1) to the hardest (10). thxs
What happens if you put copper into silver sulfate?
Silver has a higher reduction potential than copper (ie silver "wants" to be in reduced form - metalic form - "more" than copper does). If silver METAL (Ag0) is added to a solution of CuSO4, nothing happens since silver is already reduced and it wants to stay that way.
What material is softer lead or copper?
lead, copper is a metal therefore it is harder
Is silver more reactive than copper?
Suspend a copper wire in a solution of silver nitrate. Over the course of a few hours the silver nitrate will convert to copper II nitrate, turning the solution blue. Elemental silver will precipitate.
Which is heavier by volume silver or copper?
Gold has a specific gravity of 19.29, silver has a specific gravity of 10.46. Gold is heavier.
What element is harder than gold but softer than copper?
Silver is harder than gold but softer than copper.
Why is gold more valuable than copper or silver?
It si much rarer and harder to extract
Is silver harder than 9 carat gold?
Silver is softer than 9 carat gold. Gold alloys like 9 carat gold are typically harder due to the addition of other metals like copper and zinc, making them more durable for everyday wear compared to pure silver.
Is bronze as a metal harder than sterling silver?
Bronze is typically harder than sterling silver. This is because bronze is an alloy made from copper and tin, which makes it stronger and more durable compared to sterling silver, which is a softer metal due to its composition of 92.5% silver and 7.5% other metals.
Why is copper-nickel alloy used for 'silver' coins instead of silver?
There are a number of reasons:Copper-nickel alloy is much cheaper than silverIt is harder, so lasts longerIt tarnishes less readily than silver
Why were the tools for the bronze age stronger than those of earlier times?
Answer: The new smelting processes made them stronger -Apex
Is copper denser than silver?
Yes, silver is more dense than copper. Ag is 10.5 g/ml and Cu is 8.96 g/ml.
Is brass harder than silver?
Yes, brass is generally harder than silver. Brass is an alloy made of copper and zinc, which gives it increased hardness compared to pure silver. Silver is a soft metal that is more malleable and ductile than brass.
Is silver heavier then copper?
Silver is almost twice as heavy as copper.
What element does brass mimic?
Typically copper, but it is much harder than copper.
Is aluminum harder than lead or copper?
It depends on the alloy and temper of each material. Beryllium copper alloys are harder than the softest aluminum alloys, and high-strength aluminum alloys are harder than pure copper (which is quite soft). And almost every metal is harder than lead, except a few such as gold.
If copper displaces silver from silver nitrate will silver displace copper ll nitrate?
No, copper will not displace silver from silver nitrate and silver will not displace copper from copper nitrate. This is because the reactivity series dictates that silver is below copper, so copper can displace silver but not vice versa.
