Answer : The chain of many building blocks can be called as polymers in general.
Explanation : Polymers are large units of molecules in structure which are combined by the smaller repeating units called as monomers. Every macromolecule can be defined differently, like proteins are polymers made up of amino acids. Cellulose is a polymer made up of glucose monomers. The building blocks of nucleic acids are called as nucleotides.
Answer:
Given the following list of densities, which materials would float in a molten vat of lead provided that they do not themselves melt?
Densities (g/mL): lead = 11.4, glass = 2.6, gold = 19.3, charcoal = 0.57, platinum = 21.4.
glass and charcoal
Explanation:
The density of molten lead is about 10.65Kg/m^3
By Archimedes principles, the buoyancy of an object in a fluid is proportional to the mass of fluid displaced
which in turn is proportional to the object's density
Generally an object well float when placed on a denser medium
glass =2.6, and charcoal =0.57 are both less dense so they will float on Lead
E. decomposition
hope this helps!
Answer:
Increasing the concentration of a substance will increase the rate of reaction because in a conc substance the particles are more clustered together and this causes more effective collisions thus increasing the rate of reaction and when the substance isn't concentrated the particles aren't really close and this reduces the rate of reaction because alot of collisions can't be made compared to that of the concentrated substance
