Reptile [31]

1.54 x 10⁶kW

Explanation:

The problem here is converting from megawatts into kilowatts.

  Given 1540megawatts.

The mega- and kilo- watts are prefixes that denotes multiples of units.

  1 megawatt = 10⁶watts

  1 kilowatt = 10³watts

Now given 1540megawatts power to Kilowatt power;

   We see that :

   1000kW = 1mW

 1540mW x \frac{1000kW}{1mW} = 1.54 x 10⁶kW

Question 10 (1 point)
levacccp [35]
The empirical formula gives the relative ratio of atoms in each element. Therefore, it simplifies the whole numbers. For example C2H6 can be reduced to CH3 because they share the greatest common factor (2). The answer to this question would be #1. C4H10 can be reduced to C2H5 because 4 and 10 are both divisible by 2. C2H5 can not be reduced any further. All of the other options do not have a greatest common factor making them a empirical formula.
