Answer:

The answer is B to these options. (My question had an option of which one is more dense and it is medium B)

Explanation:

The more dense it will reflect and not able to go through so the angle is farther away. The less dense it will be able to slice through and be closer to normal.

Complete the following steps.
vovikov84 [41]

Answer:

See explanation

Explanation:

a) The balanced reaction equation is;

K2S + CO(NO3)2 ------> COS + 2 KNO3

b) When we include the states of matter, we have;

K2S(aq) + CO(NO3)2(aq) ----> COS(s) + 2 KNO3(aq)

c) The complete ionic equation is;

2K^+(aq) + S^2-(aq) + Co^2+(aq) + 2NO3^-(aq) ----> CoS(s) + 2K^+(aq) + 2NO3^-(aq)

Net ionic equation;

Co^2+(aq) + S^2-(aq) ----> CoS(s)

Mariulka [41]

Answer :

The name of NH_4Cl is ammonium chloride.

The name of Fe(NO_3)_3 is iron(III) nitrate.

The name of TiBr_3 is titanium(III) bromide.

The name of Cu_3P is copper(I) phosphide.

The name of SnSe_2 is tin(IV) selenide.

The name of GaAs is gallium arsenide.

The name of Pb(SO_4)_2 is lead(IV) sulfate.

The name of Be(HCO_3)_2 is beryllium hydrogen carbonate.

The name of Mn_2(SO_3)_3 is manganese(III) sulfite.

The name of Al(CN)_3 is aluminium cyanide.

Explanation :

Ionic compound : It is defined as the compound which is formed when electron gets transferred from one atom to another atom.

Ionic compound are usually formed when a metal reacts with a non-metal.

The nomenclature of ionic compounds is given by:

1. Positive is written first.

2. The negative ion is written next and a suffix is added at the end of the negative ion. The suffix written is '-ide'.

3. In case of transition metals, the oxidation state are written in roman numerals in bracket in-front of positive ions.

(a) NH_4Cl

It is an ionic compound because it is formed by the combination of one polyatomic cation (ammonium ion) and anion (chloride ion). The charge on ammonium ion is (+1) and the the charge on chloride ion is (-1).

Thus, the name of NH_4Cl is ammonium chloride.

(b) Fe(NO_3)_3

It is an ionic compound because it is formed by the combination of one polyatomic anion (nitrate ion) and cation (iron ion). The charge on iron ion is (+3) and the the charge on nitrate ion is (-1).

Thus, the name of Fe(NO_3)_3 is iron(III) nitrate.

(c) TiBr_3

It is an ionic compound because it is formed by the combination of titanium cation and bromide anion. The charge on titanium is (+3) and the the charge on bromide ion is (-1).

Thus, the name of TiBr_3 is titanium(III) bromide.

(d) Cu_3P

It is an ionic compound because it is formed by the combination of copper cation and phosphorous anion. The charge on copper is (+1) and the the charge on phosphorous ion is (-3).

Thus, the name of Cu_3P is copper(I) phosphide.

(e) SnSe_2

It is an ionic compound because it is formed by the combination of tin cation and selenium anion. The charge on tin is (+4) and the the charge on selenium ion is (-2).

Thus, the name of SnSe_2 is tin(IV) selenide.

(f) GaAs

It is an ionic compound because it is formed by the combination of gallium cation and arsenic anion. The charge on gallium is (+3) and the the charge on arsenic ion is (-3).

Thus, the name of GaAs is gallium arsenide.

(g) Pb(SO_4)_2

It is an ionic compound because it is formed by the combination of one polyatomic anion (sulfate ion) and cation (lead ion). The charge on lead ion is (+4) and the the charge on sulfate ion is (-2).

Thus, the name of Pb(SO_4)_2 is lead(IV) sulfate.

(h) Be(HCO_3)_2

It is an ionic compound because it is formed by the combination of one polyatomic anion (hydrogen carbonate ion) and cation (beryllium ion). The charge on beryllium ion is (+2) and the the charge on hydrogen carbonate ion is (-1).

Thus, the name of Be(HCO_3)_2 is beryllium hydrogen carbonate.

(i) Mn_2(SO_3)_3

It is an ionic compound because it is formed by the combination of one polyatomic anion (sulfite ion) and cation (manganese ion). The charge on manganese ion is (+3) and the the charge on sulfite ion is (-2).

Thus, the name of Mn_2(SO_3)_3 is manganese(III) sulfite.

(j) Al(CN)_3

It is an ionic compound because it is formed by the combination of one polyatomic anion (cyanide ion) and cation (aluminium ion). The charge on aluminium ion is (+3) and the the charge on cyanide ion is (-1).

Thus, the name of Al(CN)_3 is aluminium cyanide.
