Answer: a) 2H2 + O2 --> 2H2O
Explanation: 2 compounds are combining to form a new compound. The others have 2 substances as the end result and synthesis only produces one result (2H2O in this case)
Answer:
Explanation:
This question is asking to convert a measurement in kilometers to meters
Answer : Option C) An induced dipole will be produced in the molecule on the right.
Explanation : As per the given information there is a polar molecule which is placed on the left side which has partial positive charge at one end and on other end has partial negative charge which shows that it has a dipole in it. It tries to induce the non-polar molecule which is at right side. So, there will be an induce dipole interaction between both when they are placed closer to each other.
Answer:
Positive: a and b
Negative: c
Explanation:
The entropy (S) is the measure of the randomness of the system, and it intends to increase. The randomness can be determined by the energy of the molecules, their velocity and how distance they are between the other molecules.
When the entropy increases, ΔS is positive, when the entropy decreases, ΔS is negative. So, when gasoline mix with air in a car engine, the process intends to continue, the randomness increases and ΔS is positive. When hot air expands, the distance between the molecules increases, so ΔS is positive.
But, when humidity condenses, the molecules stay closer, so there's a decrease in the randomness, then ΔS is negative.
