Answer:
<h2>If we mix equal amounts of an acid and a base then two chemicals essentially cancel out each other and produce </h2><h2>salt and water. Mixing equal amounts of a strong acid with strong base results in a neutral solution whose pH value remains 7 and this type of reactions are known as neutralization reactions.</h2>

Answer:
303.4 millimeters
Explanation:
Just multiply 1.64 by 0.185. then convert that answer to millimeters
Answer:
14 % (to the nearest percentage)
Explanation:
We must first obtain the molar mass of diethyl ether rom its molecular formula, C4H10O.
relative atomic mass of carbon =12, hydrogen =1 oxygen -16
Hence we have;
(4*12) + (10*1) +16 = 48 + 10 + 16 = 74g/mol
mass percent = total mass of hydrogen/ molar mass of compound * 100
% by mass of hydrogen = 10/74 * 100 = 14 % (to the nearest percentage)
