Furkat [3]4 years ago
4 0

Answer:

Transition state Activation energy (30 - (-15) = 45 KJ E (KJ) AB Enthalpy change (20 - (-15) = 35 KJ A+B Progress of reaction

Transition state Activation energy (85 - 65) =20 KJ E (KJ) C +AB Enthalpy change (30-65) =-35 KJ CB + А Progress of reaction

Transition state Activation energy (75-10) = 65 KJ AD +BC Enthalpy change (60-10) =50 KJ AB + CD Progress of reaction

Diuris are common orchids found in Australia. The flowers of this species display a large number of variations in color and mark
Strike441 [17]

From what we know, we can confirm that the variations in colors are a mechanism intended to protect the plants from predators.

<h3>Why is color a protection mechanism?</h3>

This can be observed throughout nature. Many poisonous organisms have evolved bright colors intended to be noticed. Over time, this has resulted in many predators avoiding prey with bright colors, in order to avoid the possibility of being poisoned.

Therefore, we can confirm that the variations in colors are likely a mechanism intended to protect the plants from predators.

Between a water molecule and an anion, like Cl-, a _____A_____ occurs between a _____B_____ of the water molecule and the anion.
AVprozaik [17]

Between a water molecule and an anion, like Cl-, a hydrogen bon occurs between hydrogen atom of the water molecule and the anion.

<h3>What is hydrogen bond?</h3>

Hydrogen bond is a weak bond between two molecules resulting from an electrostatic attraction between a proton in one molecule and an electronegative atom in the other. Hydrogen atom in water molecule attract anion due to presence of hydrogen bond.

So we can conclude that hydrogen bond occurs between hydrogen atom of the water molecule and the anion.

How do you know sodium is highly reactive?
Stells [14]
<span>Na (sodium) is highly electropositive. Its has 1 electron in its outermost orbit which is transferred to an electronegative atom to form an ionic bond.

It only needs to get rid of one valence electron to take part in a reaction. That's how it's highly reactive.</span>
