Remember that the formula to calculare KA is the following
<span>Ka = [H+ ion]*[conj. base] / [acid]
</span>Now that you have the data you can do as the following:
<span>Ka = [H+]*[base] / [acid] </span>
<span>Ka = [x]*[x] / [acid - x] </span>
<span>Ka = x^2 / [acid - x]
</span>then we go
<span>Ka = [.032]^2 / [.220 - .032]
</span>Ka = <span> 5.4 x 10^-3.
Or what is the same
Ka = </span><span>.0054

Answer:
The lithosphere is broken into separate sections called plates. The geological theory that states that pieces of Earth's lithosphere are in constant, slow motion, driven by convection currents in the mantle is plate tectonics.
<span>Molecules are having the same chemical formula same number of atom but different three dimensional shapes are called <u>isomer</u>. Cis trans isomers maintain the same covalent partnerships,but atom may arranged differently.There are two or more compounds arranged in same molecular formula but different arranged atoms are seen in this molecule with different structure of it.</span>
Answer:
Chemical equation:
HNO₃ + Al(OH)₃ → Al(NO₃)₃ + H₂O
Explanation:
Chemical equation:
HNO₃ + Al(OH)₃ → Al(NO₃)₃ + H₂O
Balanced chemical equation:
3HNO₃ + Al(OH)₃ → Al(NO₃)₃ + 3H₂O
Ionic equation:
3H⁺ + 3NO⁻₃(aq) + Al(OH)₃(s) → Al³⁺(aq) + 3NO₃⁻¹(aq) + 3H₂O(l)
Net ionic equation:
Al(OH)₃(s) + 3H⁺(aq) → Al³⁺(aq) + 3H₂O(l)
The NO⁻₃ are spectator ions that's why these are not written in net ionic equation. The water can not be splitted into ions because it is present in liquid form.
Spectator ions:
These ions are same in both side of chemical reaction. These ions are cancel out. Their presence can not effect the equilibrium of reaction that's why these ions are omitted in net ionic equation.
Answer:
42.9
∘
C
Explanation:
The idea here is that the problem is providing you with the amount of heat needed to raise the temperature of a given sample of water from an initial temperature to its boiling point, i.e. to 100
