Is mercury the lightest substance in between aluminium lead and copper?
At "normal" temperatures, Mercury is denser than any of those substances ... slightly more so than lead, somewhat more so than copper, and a lot more so than aluminium.
Why is bronze harder than pure copper?
Bronze is an alloy made of copper and tin, which forms a crystalline structure that makes it harder than pure copper. The presence of tin in the alloy strengthens the material and alters its properties, including increasing its hardness.
Why bronze is not as malleable as copper?
Bronze is not an element because it is made up of more than one type of atom. It is an alloy made up of different metallic elements, such as copper and tin (An alloy is made of a metal and a metal/non-metal). This means that Bronze cannot be considered an element because it is made up of different atoms.
Why can iron be used to extract copper?
Iron is a more reactive metal than copper, and so will replace it in a compound. The more reactive a metal is, the more stable it is in a compound, and the less stable it is in its elemental form. So relative to one another, iron is more stable in a compound while copper is more stable as apure element.
Why is one mole of aluminum larger than one mole of copper?
It isn't. The mass of one mole of aluminum is less than the mass of one mole of copper. The number of atoms in one mole of aluminum is the same as the number of atoms in one mole of copper, which is 6.022 x 1023, also known as Avogodro's number.
What is heavier 1kg of lead or 1kg of copper?
The lead and the copper will weigh the same. But there will be less lead than copper by volume if both materials are solids. And that's because lead is more dense than copper. A given volume of lead weighs more than that same volume of copper. It turns out that 1kg of something will weigh the same as 1kg of something else, though the two may have different volumes for that weight. A kg of lead takes up a lot less room (volume) than a kg of ping pong balls, even though they both weigh the same.
Which is have a greater volume 1 kilogram of copper and 1 kilogram of iron?
Oh, what a lovely question! You see, both 1 kilogram of copper and 1 kilogram of iron have the same weight because they both weigh 1 kilogram. However, copper is denser than iron, so a 1-kilogram block of copper will take up less space than a 1-kilogram block of iron. It's all about how tightly packed the atoms are in each material.
Why a bar of the brass is harder than a bar of copper?
Because brass is an alloy of copper & zinc - the zinc atoms change the geometry of the copper crystals - making it less flexible.
How many moles are present in 1 g?
It depends on the substance. Remember that moles are a unit of amount, and one mole is 6.02 × 1023 atoms. So if you have lead and hydrogen, they are obviously going to weigh differently. It would take far fewer atoms of lead to amount to 1 gram; therefore, less moles. However, one hydrogen atom has far less mass than one lead atom, and would need more atoms (and moles) to make one gram.
What is the product for the reaction between lead acetate and copper sulfate?
Lead is less reactive than copper, so the sulphate ion would stay bound to the copper, so the answer is the same compounds as you started with.
How does the mass of zinc penny compare to a copper penny?
Copper pennies (95% copper, 5% zinc) weigh 3.11 grams. Modern zinc pennies (97.5% zinc, 2.5% copper) weigh 2.5 grams.
Does a mole of neon atoms weigh the same as a mole of aluminum atoms?
No. Think of it this way - say you had 20 basketballs and 20 bowling balls. Will the basketballs weigh the same as the bowling balls? No, because an individual basketball weighs less than a bowling ball, so if you have equal numbers of them, they aren't going to weigh the same. Now take 6.02 × 1023 atoms (one mole) of neon and 6.02 × 1023 atoms of aluminum. One atom of neon is going to weigh less than one atom of aluminum, so equal numbers of them aren't going to weigh the same.
Do protons in a very large nucleus have a greater chance of flying apart?
Sort of... The general tendency is for a larger atom to be less stable. Above a certain point (after lead) no stable atoms are known to exist.Sort of...

Which is heavier lead or solder?
Lead. The densities of lead and tin are 11.34 g/cm^3 and ~7 g/cm^3, respectively. Lead solder is an alloy made of mostly lead and tin; a mixture of lead and tin will weigh less than 100% lead. Lead-free solders are made of tin, copper, silver, indium, bismuth, zinc, antimony, and other metals; none of these metals is heavier than lead. So, lead is the champion.
What percentage of silver is a 1964 quarter that appears to have a copper layer?
No 1964 silver quarter should have a copper layer and they all should be 90% silver, although it is possible that your quarter has tarnished or toned odd and just appeared to look non-silver. Both copper-nickel clad and silver quarters were produced in the mid-1960s with the clad ones being dated 1965 and later while the silver ones were dated 1964, so theoretically it could be struck on a copper-nickel planchet. I would weigh the coin, a silver one should weigh about 6.25 grams (naturally a worn quarter would weigh less) while a copper-nickel one should weigh much less, about 5.67 grams.
Explain Will kg of hydrogen contain more atoms than kg of lead?
Since,1 gram of hydrogen contains= 6.02*10 raise to power 23therefore, 1000 grams of hydrogen contains = 6.02*10raise to power 23 * 1000 i.e 6.02*10raise to power 26!!nd 207 grams of lead contains=6.02*10 raise to power 23therefore 1 gram of lead contains= 6.02*10 raise to power 23 / 207hence .. 1000 grams of lead contais= 6.02 * 10raise to power 23 * 1000 / 207= 29.08 * 10 raise to power 23Hence we can say tht hydogen contains more no. of atoms !!
Is lead pipes cheaper than copper pipes?
yes but lead contaminates water and lead is bendy so not very effectiveLead pipe is Amazing for long lasting drainage, especially on chemical and acid waste systemsPer pound copper cost more but tubing weights a lot less the lead "D" drainage. Therefore lead cost a lot more
