If u put in the values of x U will see that it equals the corresponding y value.
Answer:
He spent on 16 minutes
Step-by-step explanation:
Given
per minute
Required
Determine the number of minutes
Let the number of minutes be n
<em>If 1 minute costs $0.5</em>
<em>n minutes would cost $0.5n</em>
The relationship between the given parameters is
Substitute values for each of the above
Solve for 0.5n
Solve for n
<em>He spent on 16 minutes</em>
Answer:
you gayyyyyyy
Step-by-step explanation:
Answer:
The correct statements are :
1. The enthalpy of the reaction is -184.6 kJ, and the reaction is exothermic.
2. The enthalpy of the reaction is 184.6 kJ and the reaction is endothermic.
Step-by-step explanation:
Enthalpy of reaction is amount of heat absorbed or released during the reaction.
If energy is required, enthalpy of reaction is positive and if energy is released the enthalpy of reaction is negative.
Exothermic reaction: The chemical change is accompanied by the release of heat energy
Endothermic reaction: The chemical change is accompanied by the absorption of heat energy.
So, from the above definitions, it is clear that the enthalpy of reaction of a exothermic reaction is negative and that of a endothermic reaction is positive.
Ummm I don’t know sorry I’ll come back to help you answer it
