D) a highly spontaneous reaction always occurs rapidly. 9. for an unknown compound the enthalpy of vaporization is found to be 31.7 kj/mol and the entropy of vaporization is found to be 79.9 j/(k mol). calculate the normal boiling point of this compound on the celsius scale. (hint: the reaction is at equilibrium at its boiling point.) a) 124°c b) 3°c c) 48°c d) 0.4°c e) none of these is correct

Iwould say d. eye contact and body language because you aren’t using any spoken communication. hope this : )

In a right-angled triangle: 1- the hypotenuse is the longest side2- we can apply pythagorean rule which states that: (hypotenuse)^2 = (side1)^2 + (side2)^2for the given triangle,longest side is 15 cm  side1 = 9 cmside2 is 12 cm  to check whether the triangle is right-angled or not,compare (15)^2 to the summation of (9)^2 and (12)^in other words, compare 225 to the summation of 81 and 144if they are both equal, then the triangle is right-angles, otherwise, it is not.you haven't provided the diagram showing her work, so i cannot tell the choice. however, apply my explanation to the question you have.

Add the map and the options so i can further you, you so much. : )
