Answer:
Explanation:
Molar mass of KF= 39 + 19= 58g/mol
Mass of KF = 109g
Amount = mass/molar mass
Amount = 109/58
Amount = 1.9moles
Answer:
[OH-] for this solution is 4.255*10^-12
Explanation:
We are given
[H+] = 2.35 × 10-3 M
we need to find the concentration of [OH-]
we know from Equilibrium
[H+][OH-] = 10^-14
[OH-] = 10^14/2.35*10^10^-3
[OH-] = 0.4255*10^-11
[OH] = 4.255*10^-12
Therefore the Concentration of [OH-] for this solution is 4.255*10^-12
Answer:
<em><u>Isozymes</u></em>
Explanation:
Isozymes are enzymes that differ in amino acid sequence but catalyze the same chemical reaction. These enzymes usually display different kinetic parameters, or different regulatory properties.
The compound HF is an acid. This is because it dissociates in water to give hydrogen ions (H⁺) as the only positively charged ions.
The others dissociate as follows: NH₃ reacts with water to form an alkaline solution NH₄OH.
LiF dissolves to form an ionic solution
KOH dissociates in water to form an alkaline solution.
