Answer:
Yes
Step-by-step explanation:
s<30
Put in 28 for s
28<30
Twenty eight is less than 30 so it is a solution
Given that I no not see any explanation in the previos answer, I think you can benefit of this.
Exothermic refers only to the fact that the reaction releases energy in the form of heat when occurs. So, the enthalpy is higher at start and lower and the end.
Seen in this way, you can deduct that the change in enthalpy is negative, which is what the third option says.

Answer: 105 meters
Step-by-step explanation:
Ostrich's running rate is 63 meters/3 seconds. This can be reduced to 21 meters/second (21 m/s).
(21 m/s)*(5 sec) = 105 meters
