Two descriptions about physical quantities are given below: Quantity A: It remains constant.
Quantity B: It depends on gravitational pull.
What quantities are these most likely describing?
a Both Quantity A and Quantity B are mass.

b Both Quantity A and Quantity B are weight.

c Quantity A is weight and Quantity B is mass.

d Quantity A is mass and Quantity B is weight.

quantity A is mass and quantity B is wieght

why do the isotopes of a particular element behave differently in nuclear reactions but the same in chemical reactions? chemical reactions involve changes to electrons in an atom; isotopes do not differ in electrons, and so they react the same way during chemical changes.

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
