The Weak Ionization constant (Ka) for HCOOH is equal to:<br><br><br> Please help me lol
iris [78.8K]

Answer:

Ka=\frac{[H^+][HCOO^-]}{[HCOOH]}

Explanation:

Hello,

In this case, the weak ionization reaction for formic acid is:

HCOOH(aq)\rightleftharpoons H^+(aq)+HCOO^-(aq)

In such a way, we simply recall the law of mass action in order to represent the weak ionization constant, Ka, for such process, by taking into account that the concentration of products is divided over the concentration of reactants as shown below:

Ka=\frac{[H^+][HCOO^-]}{[HCOOH]}

Best regards.

Which of the reactions are spontaneous (favorable)? DHAP − ⇀ ↽ − glyceraldehyde-3-phosphate Δ G = 3.8 kJ / mol DHAP↽−−⇀glycerald
Tpy6a [65]

Answer:

Explanation:

In spontaneous reaction , there is decrease in Gibb's free energy .( Δ G is negative ). Out of given reaction , following reactions have negative Δ G so they are spontaneous.

C ₂ H ₄ + H ₂ Rh ( I ) −−−→ C ₂ H ₆ ,  Δ G = − 150.97 kJ / mol

C ₆ H₁₃O₉ P + ATP ⟶ C ₆ H₁₄ O₁₂ P₂ + ADP ,  Δ G = − 14.2 kJ / mol

Hexane and hexene are hydrocarbon compounds from different homologous series. the combustion of these two compounds produce diff
AURORKA [14]

Answer:

Percentage of carbon of alkene is higher compared to the alkane that has the same number of carbon per molecule. Because of this, combustion of alkene will produce more sooty flame compared to their corresponding alkane and because Alkenes have a higher percentage of carbon compared to their corresponding alkane.

Explanation:

Relative atomic mass : C= 12 and H=1

Percentage of Carbon Hexane (C6H14)

Percentage of Carbon = 83.7 percent

6(12) x 6(12) +14(1) x 100 percent= 83.7 percent

Percentage of Carbon Hexene = 85.7 percent
