Hydrogen sulfate reacts with water to produce sulfate ions and hydronium ions: hso4−+h2o⇌so42−+h3o+ identify the conjugate acid-

Angelina_Jolie [31]

The generic equation for a reaction between an acid and water is

$HX_{(aq)} + H_{2}O_{(aq)} --> X_{(aq)}^{-} + H_{3}O_{(aq)}^+$

When an acid "reacts" with water, water acts as the base that accepts the proton (H+) from the acid. The remaining ion that is formed after the acid has donated its proton is called the conjugate base ( $X^-$ ), and the conjugate acid-base pair is $HX$ - $X^-$ .

Hydrogen sulfate ( $HSO_{4}^-$ ) is an ion from sulfuric acid. It is still an acid in itself and can "react" with water (( $H_{2}O$ ) to form the sulfate ( $SO_{4}^2-$ ) and hydronium ( $H_{3}O^+$ )ions.

$HSO_{4(aq)}^{-} + H_{2}O_{(aq)} --> SO_{4(aq)}^{2-} + H_{3}O_{(aq)}^+$

Based on the previous discussion, $SO_{4(aq)}^2-$ is identified to be the conjugate of the acid $HSO_{4(aq)}^-$ . Thus, the conjugate acid-base pair is $HSO_{4(aq)}^{-} - SO_{4(aq)}^{2-}$ .

Chlorine gas can be prepared in the laboratory by the reaction of hydrochloric acid with manganese(IV) oxide:You add 40.7 g of M

Alex787 [66]

:<span> </span><span>4 HCl + MnO2 → MnCl2 + 2 H2O + Cl2

(33.7 g MnO2) / (86.93691 g MnO2/mol) = 0.38764 mol MnO2
(45.3 g HCl) / (36.4611 g HCl/mol) = 1.2424 mol HCl

(a)
1.2424 moles of HCl would react completely with 1.2424 x (1/4) = 0.3106 mole of MnO2, but there is more MnO2 present than that, so MnO2 is in excess and HCl is the limiting reactant.

(b)
(1.2424 mol HCl) x (1 mol Cl2 / 4 mol HCl) x (70.9064 g Cl2/mol) = 22.0 g Cl2

(c)
(77.7% of 22.0 g Cl2) = 17.1 g Cl2</span>

On what carbon atoms does the 14CO2 used to synthesize malonyl-COA from acetyl-coa appear in palmitate?

zvonat [6]

14 carbon atoms do the 14CO2 used to synthesize malonyl-COA from acetyl-CoA appear in palmitate.

Acetyl-CoA is carboxylated into malonyl-CoA by the acetyl-CoA carboxylase enzyme. The joining of one acetyl-CoA molecule and one bicarbonate molecule requires energy from ATP.

Malonyl coenzyme A: acyl carrier protein transacylase is an enzyme that uses malonyl-CoA in the production of fatty acids (MCAT).

The highly controlled acetyl-CoA carboxylase (ACC) in the cytoplasm produces malonyl-CoA by carboxylation acetyl-CoA in biotin and ATP-dependent manner. Acetyl-CoA carboxylase is an enzyme that changes acetyl-CoA into malonyl-CoA. Malonyl-ACP is created when the malonyl group is added to an acyl carrier protein.

A condensation reaction between malonyl-ACP and acetyl-CoA results in acyl-ACP and the simultaneous release of CO2.
