<span>The zigzag line in the periodic table separates the metals from the nonmetals.</span>
Answer:
FALSE
Explanation:
Sedimentary rocks are defined as those rocks that are formed due to the combined effect of compaction and cementation process. In order to form sedimentary rocks, at first, the sediments that are transported from other places must be deposited. This deposited sediments over a due course of time, are subjected to high compaction due to the weight of the overlying weight. This results in the transformation of loose sediments into hard rocks. This how sedimentary rocks are formed which are comprised of sand-size particles. For example, Shale, Sandstone, and Mudstone.
Thus, both the compaction and cementation processes are important for the formation of sedimentary rocks.
Hence, the above-given statement is False.
<span>Because copper (II) cations have a charge of +2 and phosphate anions have a charge of -3, the formula of anhydrous* copper (II) phosphate is
Cu3(PO4)2
This shows that each formula unit contains 2 atoms of phosphorus. Therefore, the atoms of phosphorus in 4.8 formula units is
4.8 x Avogadro's Number (</span><span>6.022x10*23)</span>, or about 2.9 X 10*24 atoms

Explanation:
From the analysis we have in the question, we must look towards a first row transition metal ion having a d^6 configuration because it yields a paramagnetic complex having four unpaired electrons and a diamagnetic complex having no unpaired electrons.
We have two possible candidates in mind, Fe^2+ and Co^3+. However, Fe^2+ does not form as many coloured complexes as stated in the question so we have to eliminate that option.
We are now left with only Co^3+. Various ligands are going to cause these various colours of Co^3+ to appear in solution.
Hence, we can deduce from all these that the nature of ligands determines the colour of the complex . Don't forget that the colour of a complex arises from crystal field splitting.
