Achemical reaction is taking place in a beaker. the side of the beaker feels cold to the touch. which type of reaction is taking place? a. exothermic, because energy is released to the surrounding b. endothermic, because energy is released to the surrounding c. endothermic, becaue energy is absorbed from the surrounding d. exothermic, because energy is absorbed from the surrounding

C. ENDOTHERMIC, because energy is ABSORBED from the surrounding

Explanation:

A process in which energy is absorbed from the surroundings and stored the new bonds being made is known as endothermic reaction. Since energy is absorbed from the surroundings, the temperature decreases.

A process in which energy is released when bonds are broken to form new ones is known as exothermic reaction. The temperature increases.

In the given situation, the beaker feels cold when touched while a chemical reaction is going on inside it. It means energy is being absorbed from the surroundings thus temperature is dropping and the beaker feels cold. The chemical reaction must be endothermic reaction.

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
