Which element has the smallest atomic radius? calcium potassium scandium titanium
Alex787 [66]

 The element  that has the smallest  atomic radius is  <u>titanium</u>


          <em><u>explanation</u></em>

  • Calcium,potassium,  scandium and titanium are in  period  4 in the periodic table.
  • Generally  the atomic   radius    decreases  across the period (from the left to the right) .  This is because  across the period  there is increase  in nuclear charge  which  make electrons been strongly attracted to the nuclear.
  • Titanium is in atomic number 22 thus it has  more nuclear  charge  that  calcium,potassium and  scandium therefore  titanium has the  smallest atomic radius.

ammonium bromide reacts with copper(i) sulfate in aqueous solution to form a solid precipitate. what is the net ionic equation f
sukhopar [10]

Answer:

Br^-(aq)+Cu^+(aq)\rightarrow CuBr(s)

Explanation:

Hello,

In this case, the molecular chemical reaction is written as:

2NH_4Br(aq)+Cu_2S(aq)\rightarrow 2CuBr(s)+(NH_4)_2SO_4(aq)

In such a way, considering the net ionic notation and the solid yielded copper (I) bromide, we write:

2NH_4^+(aq)+Br^-(aq)+Cu^+(aq)+SO_4^{2-}(aq)\rightarrow CuBr(s)+NH_4^+(aq)+SO_4^{2-}(aq)

Whereas ammonium and sulfate ions are spectator ions, therefore the net ionic equation is:

Br^-(aq)+Cu^+(aq)\rightarrow CuBr(s)

Regards.

What mass of water must be used to make a 1.35 m solution that contains 8.20 mol NaOH?
Sergeeva-Olga [200]
Answer is: <span>mass of water is 6.07 kilograms.
</span>b(NaOH) = 1.35 m.
n(NaOH) = 8.20 mol.
b(NaOH) = n(NaOH) ÷ m(H₂O).
m(H₂O) = n(NaOH) ÷ b(NaOH).
m(H₂O) = 8.20 mol ÷ 1.35 mol/lg.
mm(H₂O) = 6.07 kg.
m - molality.
n - amount of substance.
