Answer:

The ice record shows a period in Earth's history when there was an ice age and the global average temperature was

much colder. During this time, the ice record shows the amount of carbon dioxide in the atmosphere decreased, but the

amount of energy from the sun did not change. How did the the total amount of energy in the Earth system change, how

did this change happen, and how did it contribute to the ice age?

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 $HSO_{4(aq)}^{-} - SO_{4(aq)}^{2-}$ .

Question:

finlep [7]

Answer:

Cyclohexene doesn't exhibit this type of Isomerism. Cyclohexene is a tiny ring to exhibit the trans isomer. The Structural formula and component bonding characteristic within it limits it to show this phenomenon. Trying to force it to be trans would place a massive amount of ring strain on the molecule.

This characterises major rings within Alkene group up to cyclooctene.
