Answer : The correct options are :

2) car A and car B are moving in opposite direction.

3) car A is moving faster than the car B.

Explanation :

From the given position-time graph, we conclude that the car A shows positive slope and the car B shows negative slope. That means the object which has positive slope will move faster as compared to the object with negative slope.

In case of Car A, it is moving towards the positive direction of the position axis whereas Car B is moving towards the negative direction of the position axis which means that both cars are moving in opposite direction.

So, the car A is moving faster than the car B and both cars are moving in opposite direction.

Consider the reaction hc2h3o2(aq) h2o(l) → h3o (aq) c2h3o2–(aq). Which species is the conjugate acid?a. C2h3o2-(aq)b. H2o(l)c. H
saul85 [17]

The species that is the conjugate acid is HC₂H₃O₂(aq). The correct option is d.

<h3>What are conjugate acid?</h3>

Conjugates acids are those acids which are made when an acid donates a proton to a base according to Bronsted Lowry theory.

In other words, we can say that it is an acid with hydrogen ion. An example is  water (base) reacting with an acid to form the hydronium ion (conjugate acid).

Thus, the correct option is d, HC₂H₃O₂(aq).
