How many seconds are there in one century? use “e” for scientific notation

The answer is 3.154e+9

If you follow the formula below you will arrive at about the same answer depending on the decimal places you want to include:

(100 years/1 century) x (365 days/1 year) x (24 hours/1 day) x (60 minutes/1 hour) x (60 seconds/1 minute)

Through the process of cancellation, you will eventually arrive at the number of seconds there are in a century because those will be the only units left in the formula.

Answerδh > 0explanationc₆h₆  (s)  → c₆h₆ (l)if you are changing it from a solid to a liquid, you are pretty much melting the solid. this requires heat energy. therefore, the reaction is endothermic (takes in energy); the system enthalpy increases as the reaction proceeds: δh > 0.
