Explanation:
two compounds because element is the very smallest part of any mixture
I Believe A is correct is correct because atoms are basically the building blocks of all type of matter, without atoms, there is no matter
B is correct as well because the amount protons of in an atom do define the element. E.g. There is 8 protons in an oxygen atom. oxygen is the 8th element on the periodic table.
C is incorrect because the atomic number is always different
D is incorrect as we already determined that Protons define the element
So A and B should be your answers
Answer:
The average atomic mass of an element is the sum of the masses of its isotopes, each multiplied by its natural abundance (the decimal associated with percent of atoms of that element that are of a given isotopе). An element does not have an absolute atomic mass.

Answer:
The value of the activation energy is 240.96 kJ/mol.
Explanation:
According to the Arrhenius equation,
The graph between log(k) and (1/T) will give straight line with negative slope along with the intercept corresponding to the value of A.
Slope f the line =
The slope of the line :
The value of the activation energy is 240.96 kJ/mol.
Well scientific laws are really laws! You can't change a scientific law and laws can be facts as well. Hope this helps!
