The percent error in the initial measurement would be 6.47%
<h3>Percent Error</h3>
Percent error in any measurement is mathematically given as:
absolute error/true measurement x 100%
In this case;
True measurement = 1.34 qt
Absolute Error = 1.34 - 1.25
= 0.09 qt
Percent error = 0.09/1.34 x 100%
= 6.47%

Answer:
The Himalayan mountain is formed at the convergent plate boundary.
Answer:
pH = 5.19
Explanation:
Mixture of acetic acid with sodium acetate produce a buffer (Buffer is defined as the mixture of a weak acid with its conjugate base and vice versa). The pH of the buffer can be determined using Henderson-Hasselbalch equation:
pH = pKa + log₁₀ [A⁻] / [HA]
<em>Where pKa is -log Ka = 4.75; [A⁻] is the concentration of conjugate base (Acetate ion) and [HA] is molar concentration of the weak acid.</em>
-You can use moles of the compounds rather than its concentrations, that is:
[HA] = 0.147 moles
[A⁻] = 0.405 moles
Replacing in H-H equation:
pH = 4.75 + log₁₀ [0.405] / [0.147]
<h3>pH = 5.19</h3>
Answer:
Correct option would be A. Mg(s) → Mg2+ + 2e-
Explanation:
Marked as correct answer on Quiz ;) (A P E X)
The theoretical yield is 0.0110 g H₂.
<em>Moles of H₂O</em> = 0.0987 g H₂O × (1 mol H₂O/18.02 g H₂O) = 0.005 477 mol H₂O
<em>Moles of H₂</em> = 0.005 477 mol H₂O × (2 mol H₂/2 mol H₂O) = 0.005 477 mol H₂
<em>Theoretical yield</em> of H₂ = 0.005 477 mol H₂ × (2.016 g H₂/1 mol H₂)
= 0.0110 g H₂
