In the reaction a+b - c, doubling the concentration of a doubles the reaction rate and doubling the concentration of b doubles the reaction rate.
which statement best describes this reaction?
a.
it is a second-order reaction in a and a second-order reaction in b.
it is a first-order reaction in a and a second-order reaction in b.
it is a first-order reaction in a and a first-order reaction in b.
d.
it is a second-order reaction in a and a first-order reaction in b.
e.
it is a zero-order reaction with respect to both reactants.

yes

explanation:

search chemistry final b exam in google and a site called quizlet will pop up

tracks, burrows, eggshells, nests, tooth marks, or gastroliths

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.
