Question- What do the monomers of all biological macromolecules have in common that allows them to assemble into large polymers? (it's not attraction forces)
I want to know how this is done please show all steps in detail
Explain why the colour of the light emitted by an element in the gaseous state is characteristic of the element & explain with a sketch diagram how a hydrogen atom, which has only one electron, has so many spectral lines.
Why is it impossible to know both the position and velocity of an atom (i.e. electron). It states this in the Heisenberg uncertainty principle...but why
To obtain a 18.0% (w/v) solution of copper sulfate (CuSO4), M.W.=160 when only the crystalline salt is available (CuSO4 5H2O, M.W.=250), what should the crystalline salt be weighed to prepare 450.0mL of solution
Suppose Milk of Magnesia is a suspension of magnesium hydroxide in water. A common medicine, it is frequently used as an antacid for the reason that it neutralizes hydrochloric acid in the stomach
Write the neutralization reaction, balance it, name the products THEN Solve the problem above.
The first order decomposition of N2O5 at 328 K has a rate constant of 1.70 × 1083 s81. If the initial concentration of N2O5 is 2.88 M, what is the concentration of N2O5 after 12.5 minutes
Problem- For the diprotic weak acid H2A, Ka1 = 2.0 × 10-5 and Ka2 = 5.0 × 10-7. Part 1) What is the pH of a 0.0750 M solution of H2A
Calculate the work(in kilojoules) done during a synthesis of ammonia(see reaction below) in which the volume contracts from 8.6L to 4.3L at a constant external pressure of 44atm.
In the left compartment there is nitrogen at 1.0 atm and 25°C; in the right compartment there is oxygen at the same temperature and pressure. Calculate the entropy and Gibbs energy of mixing when the partition is removed. Assume that the gases are..
