Answer:
a i think hope that helps
From the periodic table:
molar mass of barium = 137.2 grams
molar mass of oxygen = 16 grams
molar mass of hydrogen = 1 gram
molar mass of Ba(OH)2 = 137.2 + 2(16) + 2(1) = 171.2 grams
molar mass of 4H2O = 4 [2(1) + 16] = 72 grams
molar mass of Ba(OH)2.4H2O = 171.2 + 72 = 243.2 grams
Therefore, each 243.2 grams of <span>barium hydroxide tetrahydrate contains 72 grams of water, thus, 92.8 grams will contain:
mass of water in 92.8 grams = (92.8 x 72) / 243.2 = 27.474 grams
Based on this, when </span>a 92.8 gram sample of Ba(OH)2•4H2O (barium hydroxide tetrahydrate) is heated until water is released, 27.474 grams of water will be released.
<span>mainly the interaction of analyse and the base comes in mind and that way how solvable it is. if you but ethanol in water there is a change that it's blocking the space between the base and water and so on also let's other substances be carried away. so basically it would give lower distance for more polar and vice versa. also what kind of base are you using if it's selective for some substances </span>
Answer:
Ohm's law states that the electrical current (I) flowing in an circuit is proportional to the voltage (V) and inversely proportional to the resistance (R). ... Similarly, increasing the resistance of the circuit will lower the current flow if the voltage is not changed.
