Balance the following skeleton equation as illustrated below. h2(g) + cl2(g) + hcl (g)

H2(g) + Cl2(g) → 2HCl(g)

Explanation:

The equation should be

H2(g) + Cl2(g) → HCl(g)

All the constituents involve in the reaction are in it gaseous state(as indicated with this (g) symbol ). To balance the equation, the number of atom of elements on the reactant sides(left side) must be equal to that on the product(right side).

From the equation above the reactant side has 2 atom of hydrogen(H2) and 2 atom of chlorine(Cl2) but the number of hydrogen and chlorine atom found on the product side is 1 atom each(HCl) . so we need to balance the equation.

The balanced equation is as follow

H2(g) + Cl2(g) → 2HCl(g)

the answer is b & c i believe : )

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).
