Balance the Following Equations: Instruction: While balancing equation write the physical state of

reactants and products as well as any reaction conditions.

1) CuSO4 + KI →Cu2I2 + K2SO4 + I2

2) NH3 + O2 →NO + H2O

3)Fe2O3 + CO → Fe + CO2

4) Cu + AgNO3 → Cu(NO3)2 + Ag

5) Pb(NO3)2 + H2SO4 → PbSO4 + HNO3

6) CaCO3 + HCl → CaCl2 + H2O(l) + CO2

7)MnO2 + HCl → MnCl2 + H2O + Cl2

I will report any comments that are not appropriate for the question asked or simply typed something for the points. only answer if u know​

1. for the first question, we must find the mass of the anhydrous salt, mgso₄. the molar mass for mgso₄·7h₂o is 246.47 g/mol, while that of mgso₄ is 120.37 g/mol.7.834 g mgso₄·7h₂o * 1 mol mgso₄·7h₂o/246.47 g * 1 mol mgso₄/1 mol mgso₄·7h₂o * 20.37 g mgso₄/mol = 0.647 g mgso₄

2. mass of water = mass of sample - mass of anhydrous salemass of water = 7.834 - 0.647 = 7.19 gpercent water in hydrate = 7.19/7.834 * 100 = 91.74%

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).

it's c (engineer's do their work with mechanical stuff not on any living being)
