The reaction that describe an acid an acid- base neutralization reaction is
Be(OH)2 + H2SO4 = BeSO4 +2 H2O
Neutralization reaction involve an acid and a base reaction whereby the acid neutralization the base. for the reaction above Be(OH)2 is the base while H2SO4 is the acid thus H2SO4 neutralizes Be(OH)2 to form BeSO4 and H2O
Answer:
Explanation: Does any of this look right? To be honest I just looked it up.
Answer to question 5 is whatever expertnent you did in class.
Answer: B. It is an ether because it is unable to to form a hydrogen bond, so it is less soluble than water
Explanation: Alcohols
are more soluble in water as they can form hydrogen bonding with water whereas ethers
are less soluble as they do not form hydrogen bonds with water.
For formation of hydrogen bond, the electronegative atom (F, Oand N) must be attached to hydrogen and in ethers (ROR), there is no hydrogen directly attached to electronegative oxygen atom, thus are less soluble in water.
To know the answer, we determine the polarities of the solvent we have. Water is polar and gasoline is nonpolar. We remember that like dissolves like. Therefore, the answers are:
<span>table sugar = water
motor oil = gasoline
rubber from tire marks = gasoline
adhesive residue from a packing tape = gasoline</span>
