We define acceleration as the rate of change of the velocity
Thus, if you have positive velocity and positive acceleration, your <u>speed increases.</u>
If you have positive velocity and negative acceleration, your speed decreases.
Now you get the idea, we will see that the correct option is graph 1.
We know that the car moves towards the right (let's define this as "the car has positive velocity") and we also know that te car is slowing down constantly (thus the acceleration needs to be negative and constant).
By looking at the graphs, the only one with these properties is graph 1.

The similarity is that they both are types of bonds in molecules.
Ionic bonds are between a metal and a nonmetal.
Covalent bonds are between two nonmetals.

KE = 1/2(m)(v)^2
KE = 1/2(0.013)(8.5)^2
KE = 0.47 J
1. A) In chemical equilibrium
The sign between the reactants and products is used to represent a chemical equilibrium. In a chemical equilibrium, the rate at which product is being produced is the same as the rate at which the product is being consumed to form the reactant again.
2 B) More products form
This is in accordance to Le Chatelier's principle, which basically states that a reaction mixture at equilibrium will resist any change that is produced in it. Therefore, if the temperature is increased, the mixture will move towards the products side, which has a lower temperature due to it being an endothermic reaction.
3 A) Saturated
<span>When a solution is saturated, it is no longer able to dissolve any more solute within it. A crystal of solute sitting at the bottom is an indicator that no more solute can be dissolved, meaning the solution is saturated.</span>
