Write thermochemical equations for the formation of the following solutions, given their molar heats of solution.
1. solid sodium cyanide, AH. din = 1.21 kJ/mol
2. solid rubidium hydroxide, AH dn = -62.34 kJ/mol
Rb2O(S)+H20-2RbOH(aq)+
I
3. solid potassium bromide, AH..in = 19.87 kJ/mol
Exceeds
Use the thermochemical equations you constructed in the "Meets" section to calculate the

it have destructive character

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.

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.

i don't see a text, but i am gonna assume this *orbit* the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.
