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.
Answer:
Explanation:
Hello,
In this case, the molecular chemical reaction is written as:
In such a way, considering the net ionic notation and the solid yielded copper (I) bromide, we write:
Whereas ammonium and sulfate ions are spectator ions, therefore the net ionic equation is:
Regards.
Answer: both numbers are 2
Explanation:
Two electrons is your answer glad to help!
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.
