What is the balanced chemical equation for aqueous strontium sulfide and aqueous copper(ii) nitrate?

Aqueous strontium sulfide reacts with aqueous copper(II) nitrate to form aqueous strontium nitrate and a black precipitate of copper sulfide.

SrS (aq) + Cu(NO₃)₂ (aq) --> Sr(NO₃)₂ (aq)  + CuS (s)

The chemical equation is balanced. Both the reactant and product side of the equation have one Sr²⁺ ion, one Cu²⁺ ion, one S²⁻ ion and one NO₃⁻ ion.

in the given question, the partial pressure is calculated by using the ideal gas equation, that is, pv = nrt

here, p is pressure, v is volume = 25 l, n is number of moles = 0.0104 moles, r is gas constant = -0.0821 l.atm / mol.k

t is temperature = 273 k

p = nrt / v

p = (0.0104 mol × 0.0821 l.atm / mol.k × 273 k) / 25 l

= 0.0093 atm

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).
