You can infer that the size of sugar particles that are dissolved in a mixture of sugar and water are very small since you cannot see the sugar particles. Sugar is an organic compound which is held by covalent bonding. When we dissolve sugar in water, it does not ionizes or dissociates rather it stays as a sugar molecule dissolved in the solvent which is water. These particles are very which is impossible to be seen by the naked eye. Dissolution involves the solute particles and solvent particles interacting and attracting each other forming a solution. Sugar molecules are attracted to water since it is a polar molecule.
Answer:
78.14 % B; 21.86 % H
Step-by-step explanation:
The formula of diborane is B₂H₆.
The masses of each element are:
2B = 2 × 10.81 = 21.62 u
6H = 6 × 1.008 = <u> 6.048 u
</u>
TOTAL = 27.67 u
% B = 21.62/27.67 × 100
= 78.14 %
% H = 6.048/ 27.67
= 21.86 %
Acids are substances capable of donating hydrogen ion H⁺. On left h2po4- is acid, because that ion donate one hydogen ion to haso42-, and on the right h2aso4- is acid, because donate one H⁺ to hpo42- (when hpo42- accept one hydrogen ion, he transorms in h2po4-).
