It is:
Iron (III) Oxide

As a transition metal iron can have two oxidation states <span>F<span>e+</span>2</span> ferrous or <span>F<span>e+</span>3</span>ferric.

Oxygen has an oxidation state of <span>O<span>−2</span></span>.

In the case of <span>F<span>e2</span><span>O3</span></span> the oxidation states are balanced when 2 <span>F<span>e<span>+3</span></span></span> ions pair with 3 <span>O<span>−2</span></span>.

<span>F<span>e2</span><span>O3</span></span> is Iron (III) oxide where the roman numeral informs us that the charge on the iron is +3, the common name would be ferric oxide.

If the iron was <span>F<span>e<span>+2</span></span></span> and the oxygen <span>O<span>−2</span></span>, the formula would be FeO Iron (II) oxide or ferrous oxide.

Given that cao(s) + h2o(l) → ca(oh)2(s), δh°rxn = –64.8 kj/mol, how many grams of cao must react in order to liberate 525 kj of
USPshnik [31]

Answer:

454.3 g.

Explanation:

  • From the given data:

1.0 mol of CaO liberates → – 64.8 kJ.

??? mol of CaO liberates → - 525  kJ.

∴ The no. of moles needed = (1.0 mol)(- 525 kJ)/(- 64.8 kJ) = 8.1 mol.

<em>∴ The no. of grams of CaO needed = no. of moles x molar mass</em> = (8.1 mol)(56.077 g/mol) = <em>454.3 g.</em>

Because of its high reactivity which element is normally obtained by the electrolysis
katrin [286]

<span>Lithium has a property of high reactivity and to obtain lithium is through electrolysis of its fused salts. Because lithium is very reactive, it is not found free so electrolysis is use to split it apart to get it.  Moreover, Lithium is an alkali metal with single valence electron that is easily given up to form cation, which make it a good conductor of heat and electricity.</span>
