Answer:
17%
Explanation:
Given parameters:
Atomic mass of nickel isotope = 57.9g/mol
Experimental value of atomic mass = 59.6g/mol
Unknown:
Percentage error in the measurement.
Solution:
The percentage error shows how much uncertainty was introduced into a measurement. To calculate this, we simply use the expression below:
Percentage error =
Percentage error = x 100 = 17%
True. Water acts as a solvent as the solute dissolves into water.
Yes, if we're talking about intramolecular bonds

PLZ HELP ME. This is my second time posting my question because the first time a person put a random answer. If you do not know the question please do not answer it and leave it to someone else. Thank you, and my question is on the attached image below.
Radioactive always means first order reaction
the half life of a first order reaction is t(1/2)=ln(2)/k. addtional info is needed to complete the calculations but this will determine the rate constant k. then for a first order reaction: <span>ln[A] = ln[Ao] - kt where [A] is the final amount left after time t (3 weeks) and [Ao] is the inital amount. </span>
