Find the mass in grams of 2.00 x 10^23 molecules of C10H15O

119.13 g C10H15O

Explanation:

First you have to convert the molecules to moles-

2.00×10^23 molecules ( 1 mole/ 6.02×10^23 molecules)

Then convert the moles to grams (you will need a periodic table)

Looking at the periodic table, we see that C=12, H=1, and O=16

so if we add 15 O's, 10 C's and 1 H, we get 361 g.

0.33 moles ( 361 g/1 mole )= 119.13 g

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.

hope this .
