Answer:
b. the layer of oxide formed on statues made of metal
Explanation:
Chemical weathering is a process whereby rocks are disintegrated or weathered causing a chemical reaction thereby leading to change in the parent rock constituents .
In chemical weathering a new substance is usually formed after the weathering takes place.
From the question the layer of statue made by metal will likely form oxides of those metals. Example Silver will react with oxygen to form an entirely new substance like silver(i)oxide.

Hi just a reminder don’t click the links, and 11.0 is correct
Answer:
Atomic #: 82
Mass #: 206
Charge: 4+
# of protons: 82
# of electrons: 78
# of neutrons: 124
Explanation:
Atomic #: look at the bottom left #, it's always the atomic #.
Mass #: look at the top left # it's always the mass #.
Charge: they give you the charge which is shown on the upper right of the element.
# of protons: is the atomic #
# of electrons: also the atomic # minus 4 bc the charge is a positive 4, indicating that some electrons 'left'.
# of neutrons: 206 (mass # is protons + neutrons) minus 82 (atomic#) which is 124.
Answer:
1.52M in NaCl
Explanation:
Molarity = moles solute / volume solution in Liters
=> molarity (M) = 3.8 moles / 2.5 Liters solution = 1.52 molar solution in NaCl
