If you place a piece of magnesium ribbon into some dilute acid, it fizzes and gives off hydrogen gas.
a State which one of these would not change the rate of reaction:
• increasing the surface area of the magnesium
• adding more acid
• cooling the acid down
• reducing the concentration of the acid.

answer: h+ its less than oh

explanation:

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).

the formula mass of a molecule or a compound is the sum of the atomic weights of the atoms in its empirical formula

(that's what i know about formula mass)
