The answer is <span>ionic aluminum fluoride (</span>AlF3). Note that boiling points of pure solvents are raised in the presence of solutes. The type of solute also affects the boiling point elevation of the solution. Ionic substances tend to raise it more than covalent ones, so sucrose is out of the picture. Next, consider the number of ions the ionic substance produces. The more ions, the greater the BPE. AlF3 dissociates into 4 ions.
Answer:
23.55 L
Explanation:
USe the following 'identity' of gs laws
P1 V 1 / T1 = P2 V2 / T2 ( T must be in Kelvin)
re arrange to
P1 V 1 T2 / (T1 P2) = V2 NOW SUB IN THE VALUES
752 * 34.2 * ( 34 + 273.15) / [( 229 + 273.15) * 668] = V2 = 23.55 L
Answer:
O2
Explanation:
A compound is made of two or more chemical elements. With that in mind, O2 is only one element: oxygen.
