Answer:
The answer is 1. A type of acid that completely reacts with water.
Explanation:
A strong acid dissociates completely in water to release hydrogen ions as the only positive ions.
This is the simple definition of Arrhenius acid.
Answer:
B.) an intensive property
Explanation:
Bc it is a Characteristic Property that won't change no matter what size of sample is tested
Mole is a unit that has become the way of scientist and those who are interested in the filed to count the number of substances or atoms. Thus, the answer is letter B. It will be very impractical for them to count the atoms using the natural numbers are they are very small and very numerous.
Explanation :
Actually bromine have 35 electrons when it is neutral, and if the number of electrons is increased by 1 it gains a relative negative charge of 1.
Also written as : -1
Answer:
Option c → Tert-butanol
Explanation:
To solve this, you have to apply the concept of colligative property. In this case, freezing point depression.
The formula is:
ΔT = Kf . m . i
When we add particles of a certain solute, temperature of freezing of a solution will be lower thant the pure solvent.
i = Van't Hoff factor (ions particles that are dissolved in the solution)
At this case, the solute is nonvolatile, so i values 1.
ΔT = Difference between fussion T° of pure solvent - fussion T° of solution.
T° fussion paradichlorobenzene = 56 °C
T° fussion water = 0°
T° fussion tert-butanol = 25°
Water has the lowest fussion temperature and the paradichlorobenzene has the highest Kf. But the the terbutanol, has the highest Kf so this solvent will have the largest change in freezing point, when all the molalities are the same.
