They both weight a kilogram. Lead has a higher density.
lead has much higher density
They both weigh one kg, so they should have the same weight.
Please note that a kilogram is a unit of mass - NOT a unit of weight. And yes, a pencil has a mass that is considerably less than a kilogram. For comparison, a kilogram is the mass of a liter of water.
The density of a material is defined as its mass per unit volume. A given volume of lead has more mass than a given volume of feathers. In common usage mass often refers to weight, but that is not a very exact usage of it. For this question it may be useful however to think of a given weight of lead per volume and a given weight of feathers.If you have a kg of lead, that is a small piece, a kg of feathers is a large amount.So for a given volume, say a cubic centimeter, the weight of lead is much more than the weight of feathers.
Yes, a kilogram of hydrogen will contain more atoms than a kilogram of lead because hydrogen has a lower atomic weight (1 amu) compared to lead (207 amu). Therefore, a kilogram of hydrogen will have more moles, and hence more atoms, than a kilogram of lead due to the difference in their atomic masses.
Pencil "lead" is actually made of graphite, which is an inorganic mineral. Graphite is made up of carbon atoms and is not considered organic.
There are 6 atoms in dioxide lead because there 1 hydrogen atom and 5 nitrogen atoms
No. First, lead is not organic as in order to be organic a compound most contain carbon and hydrogen. Lead is an element that contains only itself. Second, since it is a metal lead exists as individual atoms, not molecules.
Tetraethyl lead (Pb(C2H5)4) contains 4 carbon atoms, 10 hydrogen atoms, and 1 lead atom. Therefore, the total number of atoms present in one molecule of tetraethyl lead is 15.
Lead has a much higher density than water, meaning a kilogram of lead occupies less volume compared to a kilogram of water. This is due to the arrangement of atoms and molecules in lead being more tightly packed together, resulting in a higher mass per unit volume.
tetra-ethyl lead means lead and ethyl taken four times in ethyl 7 atoms will be present there fore in tetra ethyl 28 atoms will be present.i9n tetra-ethyl lead 1 lead atom will be present so in total 28+1=29 atoms will be present in tetra-ethyl lead.
4.56 kg of what? 4.56 kg of hydrogen has a different volume than 4.56 kg of lead.
Lead (Pb)
This statement is incorrect. A kilogram of lead always weighs the same as a kilogram of air since they both have a mass of one kilogram. However, lead is denser than air, so a kilogram of lead will occupy less space compared to a kilogram of air.
They both weight a kilogram. Lead has a higher density.
A kilogram of water and a kilogram of lead have the same mass, but lead is denser than water. Lead has a higher density because it has more mass packed into a smaller volume compared to water.
