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?
When copper is put into silver sulfate, a displacement reaction occurs where the copper displaces the silver in the compound forming copper sulfate and silver metal. This is because copper is more reactive than silver and will replace it in the compound.
What material is softer lead or copper?
Lead is softer than copper. Lead is a relatively soft and malleable metal, while copper is harder and more durable.
Is silver more reactive than copper?
No, copper is more reactive than silver. Copper is more likely to undergo redox reactions and form compounds with other elements compared to silver. Silver is relatively unreactive and does not readily react with most substances.
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 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 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 silver heavier then copper?
Yes, silver is heavier than copper. Silver has a density of 10.49 g/cm³ while copper has a density of 8.96 g/cm³. This means that silver is denser and heavier than copper for the same volume.
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.
What element does brass mimic?
Typically copper, but it is much harder than copper.
Which is harder-------------- copper or diamond?
Diamond is harder than copper. Diamond is the hardest naturally occurring material with a rating of 10 on the Mohs scale, while copper has a much lower rating of 3.
