I believe the correct response is A.
Answer: In a half-cell is where occurs the either oxidation (loss of electrons) or reduction (gain of electrons) but not both.
Explanation:
1) In an electrolitic cell you can identify two half-cells.
2) In one half-cell occurs the oxidation
3) In the other half-cell occurs the reduction.
4) The half-cell where oxidation occurs is the anode.
In the anode the spieces increase its oxidation number, which is what oxidation means. Increasing the oxidation number means that the spieces is losing electrons.
5) The half-cell where reduction occurs is the cathode.
Reduction is the reduction of the oxidation number and this occurs due to the gain of electrons.
Answer:
By Newton's laws. we know that when we apply a force in an object, then we also are applying acceleration, given by the equation F =ma, where F is the applied force, m is the mass of the object and a is the acceleration.
Now in this problem, we only have that James want to move objects from point A to point B. If the problem says that James does it at the same time for each object, then we could assume that each object has the same acceleration A.
F = m*A
then if the mass of the o
object increases, the force needed to move it at the given acceleration will increase also, then the object that requires less force is the object with less mass, in this case, the toy car.
But in this problem never says that the objects are moved with the same acceleration (or in the same amount of time), then we could apply the same force in the four objects and eventually the four will get to the point b ( for example, the refrigerator would take a lot more of time than the toy car.

The answer is (3) HCl. The definition of electrolyte is a substance which forms ion in an aqueous solution. Usually it is an ionic compound. While CCl4, C2H6, and H2O are covalent compounds.
