Igive 15 points +++ ! three types of chemical reactions are synthesis, decomposition, and replacement. in a synthesis reaction, two or more elements or compounds combine to form a more complex substance. a decomposition reaction occurs when compounds break down into simpler products. in a replacement reaction, one element replaces another element in a compound (single replacement) or two elements in different compounds trade places (double replacement). compare and contrast what is the difference between a synthesis and a decomposition reaction?

The two basic reaction types are synthesis and decomposition. Synthesis reactions are reactions that assemble substances together into larger molecules and/or compounds. Decomposition reactions are the opposite of synthesis reactions because they take apart larger molecules and/or compounds.

petroleum? coal maybe?

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.
