1. The option a. 10 mL has the most uncertainty associated with it, because it has only 2 significative figures, while 10.0 mL has three significant figures and 10.00 has four significant figures.
2. The volume of solution that remains is 145.675 mL - 24.2 mL = 121.475 mL rounded to one decimal = 121.5 mL, given that the measure with the most uncerntainty has only one decimal.
Answer:
What will happen to Uk if you double the mass?
Explanation:
Uk = 0.5 * m * v²
You see that both m and v are variable, which means that both m and v can be any number. Regardless of the numbers you put in for m or v, the formula to calculate the kinetic energy (Uk) remains valid.
You could ask
1. What will happen to Uk if you double the mass?
2. What will happen to Uk if you double the velocity?
please see and understand(!) that the relationship between Uk an v² is indeed the velocity squared....
EXTRA
Uk = 0.5 * m * (v)²
Suppose the m = 3kg and velocity = 5 m/s
What is the Uk?
Well if you know the formula you can use your calculator to find out:
Uk = 0.5 * m * (v)²
Uk = 0.5 * 3 * (5)²
Uk = 0.5 * 3 * 25
Uk = 37.5 kgm/s²
Again you ask what will happen to Uk if you double the velocity?
At first it was 5 m/s and now it doubles, which means it now has that value *2
The new velocity is 5 *2 = 10 m/s
Uk = 0.5 * m * (v)²
Uk = 0.5 * 3 * (10)²
Uk = 0.5 * 3 * 100
Uk = 150 kgm/s²
150 = 4 * 37.5
So now you see that if you double your velocity, the Uk will be 2² = 4 times as big !
The strongest intermolecular bonding in ethanol is hydrogen bonding.
Intermolecular forces are the forces that hold two molecules of a substance together in a given state of matter. For ethanol, the strongest intermolecular force is hydrogen bonding.
Hydrogen bonding occurs when hydrogen is directly linked to a highly electronegative element such as oxygen, nitrogen, fluorine or sulfur. The existence of intermolecular hydrogen bonds accounts for unusual properties such as abnormally high melting and boiling points.

Answer:
Ethane can be converted into 1- butanol in 4 different steps and reactions.
Explanation:
Step 1 : Ethane follows Markovnikov's rule and reacts with a protic acid called Hydrogen chloride to form Chloroethane.
Step 2: Chloroethane undergoes Wurtz reaction where it reacts with sodium metal in the presence of dry ether to form an higher alkane called butane.
Step 3: Butane undergoes chlorination where it reacts with an halogen called chlorine to form 1-chlorobutane.
Step 4: 1-chlorobutane reacts strong aqueous Potassium hydroxide (KOH) to form 1-butanol.
Attached to this answer is the handwritten conversion of Ethane to 1-butanol showing all the reagents and molecules synthesized along the way.
When copper chloride is added to water, it dissolves into the water since it is fairly soluble in water. The resulting mixture would be a solution. A solution is an example of a homogeneous mixture where it consists of a solute and a solvent. A homogeneous mixture is a type of mixture where the composition is uniform all throughout the system resulting to uniform properties as well. The opposite case is called an heterogeneous mixture where it consists of several components that are not uniformly distributed. Any point in this mixture would have different composition resulting to different properties in the mixture.
