Answer:
Explanation:
Hello,
In this case, for the dissociation of the sodium hydroxide into sodium and hydroxyl ions we have:
Which is a 100% dissociation as sodium hydroxide is a strong base, therefore, the concentration of the hydroxyl ions are 1.0x10⁻⁹. For that reason, the pOH could be computed as:
Finally, from the definition of pH, we have:
Best regards.
Answer:
One way to predict the type of bond that forms between two elements is to compare the electronegativities of the elements. In general, large differences in electronegativity result in ionic bonds, while smaller differences result in covalent bonds. the bonding is covalent bcz its between the most electronegative atom nitrogen and carbon .

Answer:
1.5 moles of H₂SO₄ needs 3.0 moles pf KOH to be neutralized.
Explanation:
- KOH is dissociate according to the equation:
KOH → K⁺ + OH⁻.
- H₂SO₄ is dissociated according to the equation:
H₂SO₄ → 2H⁺ + SO₄²⁻.
<em>So, every 1.0 mole of KOH produces 1.0 mol of OH⁻.</em>
<em>While, every 1.0 mole of H₂SO₄ produces 1.0 mol of H⁺.</em>
<em />
Thus, every mol of H₂SO₄ needs 2.0 moles of KOH to be neutralized.
<em>So, 1.5 moles of H₂SO₄ needs (2 x 1.5 mol) = 3.0 moles pf KOH to be neutralized.</em>
Answer:
Charles's law states that the volume of a given amount of gas is directly proportional to its temperature on the kelvin scale when the pressure is held constant.
