Limestone, which contains the mineral calcite that fizzes in weak acid, may change due to heat and pressure into the metamorphic rock marble. What characteristics
would you expect the marble to show?

A: it would show fossils.
B: It would not fizz in acid.
C: It would have stripes.
D: It would fizz in acid.

D: It would fizz in acid.

Explanation:

Marble is a limestone & will have an acid reaction that is similar to the limestone from which it was formed.

yup  

A: it would show fossils.

B: It would not fizz in acid.

C: It would have stripes.

D: It would fizz in acid.

Explanation:

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
