Answer:
To be enantiomers, a molecule must have at least three different atoms or groups connected to a central carbon.
Explanation:
To be structural isomers, the molecules must have the same formula and different structure, it means, the same number of each element. CH3CH2COOH and C3H6O2 have 3C, 6H, and 2O, so they can be structural isomers.
Cis-trans isomers occur in molecules with a double bond between carbons, and each carbon has to have 2 different atoms or groups connected to it.
Enantiomers are optic isomers, and to occur, the molecule has to have a chiral carbon (an asymmetric carbon), which is a central carbon connected to four different atoms or groups. So the third affirmative is false because it says that is necessary only three different atoms or groups connected to a central carbon.
This is based on your personal opinion lol but ig you can say public speaking
Kc at 457 K is 4.88 × 10⁵.
<h3>
</h3><h3>What is Kc?</h3>
The ratio of the equilibrium concentrations of the products over the equilibrium concentrations of the reactants, each raised to the power of their respective stoichiometric coefficients, is known as the equilibrium constant, or Kc.
Kp = Kc(RT)∧Δn
Kp = 1.3 ˣ 10⁴
Δn = -1
Kc = 4.88 × 10⁵.

The effect that the following changes have on the rate of
the reaction between the gases A
and B in a container when the temperature is decreased at a constant volume
will decrease because the molecules of A and B are ineracting very slowly due
to the decrease in temperature which results to the decrease in kinetic energy.
