Write the formulae and names of compounds formed by combination of
(i) fe3+ and so4 2- ii) nh4+ and co3 2-

(i) Formula = Fe₂(SO₄)₃

   Name = Iron (III) Sulfate or ferric sulfate

(ii) Formula (NH₄)₂CO₃

    Name = Ammonium Carbonate

Explanation:

Data given:

(i) Fe³⁺ and SO₄²⁻

ii) NH₄⁺ and CO₃²⁻

Formula and named of the compound =?

Solution:

(i) compound from Fe³⁺ and SO₄²⁻ and its name

writing a formula in combined form

compound formula form from Fe³⁺ and SO₄²⁻ = Fe₂(SO₄)₃

Name of the compound = Iron (III) Sulfate or ferric sulfate

(ii) compound from NH₄⁺ and CO₃²⁻ and its name

writing a formula in combined form

compound formula form from NH₄⁺ and  CO₃²⁻ = (NH₄)₂CO₃

Name of the compound = Ammonium Carbonate

mechanics (greek   is that area of science concerned with the behaviour of physical bodies when subjected to forces or displacements, and the subsequent effects of the bodies on their environment. the scientific discipline has its origins in ancient greece with the writings of aristotle and archimedes[1][2][3] (see history of classical mechanics and timeline of classical mechanics). during the early modern period, scientists such as galileo, kepler, and newton laid the foundation for what is now known as classical mechanics. it is a branch of classical physics that deals with particles that are either at rest or are moving with velocities significantly less than the speed of light. it can also be defined as a branch of science which deals with the motion of and forces on objects. the field is yet less widely understood in terms of quantum theory.

so what is the problem with your lab report and whats the subject of the lab report? i will you
