Consider the following energy diagram. how much is the activation energy? 2.4 kcal/mole 14.4 kcal/mole 43.8 kcal/mole

43.8 kcal/mole

Explanation:

Activation energy is the minimum energy required by the reactants to form the activated complex, the activated complex then gets converted to products. According to the given graph the reactants required 43.8 kcal of energy to form the activated complex.The lower the activation energy the faster the reactants will get converted to products and vice versa.  

is it a purebred? it looks more like a red nose, but it doesn't have the red could it be a staffordshire bull terrior? unsure if that's the right name for it sorry

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
