Me if 3.00 g of ch3oh is reacted with excess sulfuric acid and the actual yield of (ch3)2so4 was 0.94 g, what was the percent yield of the reaction? 2 ch3oh + h2so4  → (ch3)2so4  + h2o

So yield = actual/predicted*100

You need to find the theoretical yield. CONVERT INTO MOLES. this is the 1st step you do in most calculation questions.

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.

the answer is c
