Explanation:
to find POH u need PH first
so ph=-log(h3o)
so
MgCl2 is a ionic compound because it is formed by a metal (Mg) and a non-metal (Cl)
Answer:
Element Lithium
Explanation:
The element with the highest second ionization energy is lithium. It belongs to the alkaline metal group I.e group one metals
It has the highest second ionization energy because it is very difficult to remove the electron from the 1s orbital.
Its atomic number is 3. The electronic configuration is 1s2 2S1
The new concentration of sodium phosphate is 0.315 mol·L⁻¹.
We can use the dilution formula
:
<em>c</em>₁<em>V</em>₁ = <em>c</em>₂<em>V</em>₂
We can rearrange the formula to get
<em>c</em>₂= <em>c</em>₁ × (<em>V</em>₁/<em>V</em>₂)
∴ <em>c</em>₂ = 1.50 mol·L⁻¹ × (21.00 mL)/(100.0 mL)] = 1.50 mol·L⁻¹ × 0.2100
= 0.315 mol·L⁻¹
